C++ :: Calculate Area For 500 Different Measurements For Playground Company In Region
Feb 13, 2014
You are writing a program to calculate the area for 500 different measurements for a playground company in the region. The company must calculate square footage of each prospective playground, as well as the total cost to mulch each area. The cost of mulch changes frequently, so the company would like to be able to input the current cost per square foot of mulch each time they run the program. Since the quantity of data is large, the input should come from a file called “measurements.txt”. You can assume the file includes the length of each prospective playground, followed by the width. The file will be in the following format.
450300
120210
.
.
.
Ask the user the name of the file they would like to write to, as well as the current price of mulch per square foot. Output the area of each playground, along with the total price of mulch to the file that the user specifies. The playground company would like each column of output to be 20 characters in width. Each column should have an appropriate heading in the output file. You should format your output data appropriately. For example, for the input data displayed above, along with a $2.00 per square foot mulch price, the output would be:
Area Total Mulch Price
135000 $270000.00
25200 $50400.00

I have created a program to calculate different measurements for a cylinder. Anyways, the end user has to input 3 variables.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
The numbers are what "End User" would input. But I need to make it look like this when said "End User inputs the numbers.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
Here is what I have for it, but I don't know what to put where.
printf("
Enter the lower radius: ");
scanf("%f", &lower_rad);
printf("Enter the upper radius: ");
scanf("%f", &upper_rad);
printf("Enter slant height: ");
scanf("%f", &slant_h);

This program in not completed. I am creating a large program in order to calculate a company's weekly payroll. For now I am filling in the separate functions piece by piece before the rest of the program is completed.
Right now I am trying to use separate functions to call other functions. I need to ask the user for the file name and then open the file. I am no longer getting any compiler errors however when I run the program all it displays is "Welcome."
So it's not actually calling the NameTheFile function and the OpenTheFile function. It just says "Welcome" and then closes down. Why is it doing this?
/*Program to determine company's weekly payroll*/
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
void NametheFile() {
ifstream inputFile;

You work for a painting company. Your job is to calculate the amount of paint needed for every contract assigned to the company. This time, you need to paint an outside wall. The dimensions of the wall are 5 X 7m. The window is a circle with the radius of 1m. Write a program that would calculate the following:
The amount of paint needed knowing that you need 1 gallon per 10 square meters. The amount of time to complete the job knowing that it takes 1 hour per 10 square meters to prepare the surface, 5 minute per square meter to pant it and 5 minute per square meter to clean up the area.

I was given an assignment for class to calculate the area of a circle using only the radius as a user input and not using Pi in the code. I need to do this by calculating the areas of a series of rectangles under the curve and adding them together. Using nested loops to continuously reduce the size of these rectangles until the approximated area value is within a margin of error less than 0.1%.
Code:
#include<iostream>
#include<cmath>
using namespace std;
int main ()

#include <iostream>
#include <cmath>
using namespace std;
//prototypes for all separate functions
int chooseFunc(int);
int chooseMethod(int);
int numRect(int);
[Code] .....
It seems that my program will ask the user for the number of rectangles and trapezoids but will fail to compute the area under the curve from the user input. Therefore, I believe I have a logical error somewhere or I'm forgetting to call something somewhere.

Write a program that prompts the user to input the length of a rectangle and the width of a rectangle and then displays the rectangle's area and perimeter. The program should be broken down in 3 parts:
1. Input the length and the width (two input statements)
2. Calculate the area & perimeter (results should be saved in variables
3. print results.
Format the output so the user can easily read the results. Use the tab escape so its easy to read.
---------------------------------------------------------------
So here's what I have so far. I have been stuck for two days
#include iostream
using namespace std;
int main () {
int double length;
int width;
int area;
int perimeter;
[Code] ....
I dont want to get a zero for not turning this in...

I am writing a program to calculate a rectangle's area.
Eg.
Enter top left point: 1 1 (User input)
Enter bottom right point: 2 -1 (User input)
Top Left x = 1.000000 y: 1.000000
Bottom Right x = 2.000000 y: -1.000000
Area = 2.000000 (Program output)
It keeps on prompting me my variable r is being used without being initialized, when I think I already did so.
Code:
typedef struct {
double x;
double y;
} Point;

So for my assignment, I have to write code to calculate the surface area and volume for a rectangular prism that involves the use of functions. I made the program without functions and it works perfectly but as I'm putting in the required functions, it conversely made it non-functional, ironically. How to call functions correctly and the online book we're using now is confusing me even more.
Code:
#include <stdio.h>
#include <math.h>
int main(void) {
double x1, x2, x3, x4, x5, x6, x7, x8 = 0;
double y1, y2, y3, y4, y5, y6, y7, y8 = 0;
double z1, z2, z3, z4, z5, z6, z7, z8 = 0;
double length, width, height=0;
[Code]....
And here is the version I'm using to test it (without the need to input the individual coordinates).
Code:
#include <stdio.h>
#include <math.h>
int main(void) {
double x1, x2, x3, x4, x5, x6, x7, x8 = 0;
double y1, y2, y3, y4, y5, y6, y7, y8 = 0;
double z1, z2, z3, z4, z5, z6, z7, z8 = 0;
double volumePrism, surfaceArea =0;
[Code]...

How would this look like in C? Develop an application to calculate the area and perimeter of geometric shapes. First the user is asked to enter a letter representing the shape. We use C for circle, R for rectangle and S for square. After the user chooses the shape, the program prompts for the appropriate dimensions of the shape accordingly.
For instance, if the user has chosen a square, the program will ask for a side. If it's a circle, the program will ask for radius. If it's a rectangle, it will ask for length and width. Upon receiving the appropriate dimensions, the program will calculate the area and the perimeter of the requested shape and print it on the screen. And again, the code will ask for another letter. If the user enters 'Q' the program terminates.
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >S
Please enter the side of the square > 8
The area is 64 and the perimeter is 32
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >R
Please enter the width of the rectangle > 5
Please enter the length of the rectangle > 7
The area is 35 and the perimeter is 24
Please Enter Shape (C: Circle, S: Square, R: Rectangle Q:quit) >Q

I'm trying to use semaphores on three different processes so that each process won't enter the critical region at the same time and also go in the order: process 1 -> process 2 -> process 3. However, everytime i run the code the process 3 keeps going before process 2.
Here's my code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/ipc.h>
[Code].....
the processes should print out like this:
process 1: 100000
process 2: 300000
process 3: 600000

The first two numbers are the Particle ID and its Energy, the rest of numbers are the loss of energy(different in number for every particle).
I have to elaborate 1000 events like this and to create a function able to read every line and to count the number of the loss energy measurement.
I use ifstream to read a file text, but my problem is: my program how to understand that it's passing to the new line? I have to divided every events in Arrays of different length, so i have to count each data for every particle and then create the array.
The instruction EOF it's not good...

Assignment: Design a class to store measurements. The class should have two data items, feet and inches, both integers. The class must make sure that the number of inches never gets below zero or above 11. If inches is outside that range, adjust feet accordingly. (Yes this means feet might be a negative number.)
Create a default constructor and one which receives one integer, a number of inches.
Overload the following operators: addition, subtraction, equality, inequality, incrementation (both pre and post) (should add one to inches), and output (in the form of: F’I”)
Code:
#include <iostream>
using namespace std;
class measurements {
private:
int inches;
double feet;
[Code] ....
I am getting a LNK2019 error and an LNK1120 errors:

Make a c++ program of the payroll of a company
input values :
a. Name of Employee
b. Position in the company
c. No. of hours worked
d. No. of overtime hours
e. rate per hour
formula:
basic pay = number of hours worked x rate per hour
ot pay = overtime hours x 150% of rate per hour
gross pay = basic pay + ot pay
tot deduc = tax + sss + med
tax can be computed based on the following table:
basic pay tax
10000 or less 1% of basic pay
10001-15000 2% of basic pay
15001-20000 3% of basic pay
20001-30000 4% of basic pay
30001 or more 5% of basic pay
sss = 10% of basic pay
med = 6% of basic pay
net pay= gross pay - total ded
*The payroll should have at least 5 employees in it.*

I'm trying to get this program to return total taxi cab fair an infinite number of times, however, when I use the while statement after for and try to run the program, it just keeps displaying the first total fair rapidly.
specifications:A cab company needs a program to calculate the cost of a cab ride.
The driver will enter the length of the trip in miles.
The miles entered must be greater than 0.
Create a function to calculate the charge. The function should receive one argument, the length of the trip, and should return the total fare for the ride.
The taxi charges a fixed charge of $2.50, plus an additional charge of $1.85 per mile.
Allow the user to calculate any number of trips.
At the end display the total of all the fares.

My colleague and I have been given a task to create a list with the employes of a company using binary trees. Each employee/node has to contain the following information:
- Employe name
- Rank
- ID Number
- monthly Salary
We have to write a C program (using Codeblocks) which builds the company tree with the information above and afterwards lists all the employes who have a salary bigger then a number specified by the user.
So far so good. We've had a look on the examples on the internet and after finding one which looked friendly enough we started working on that one to suit our needs. Credits for the original source code to: C Program to Implement Binary Search Tree Traversal - Basic C Programs | C Programming Examples
We've reached the point where we're able to insert the required information but being able to list all the employes who's salary is bigger then the number given by the user seems to be rather difficult to achieve. I'll include the code next. We have left almost the entire pieces of the original code and we are aware that the are still things which are not required for our assignment, which only requires to enter the 4 information above and afterwards display the employes with the before mentioned condition concerning their salary.
Code:
# include <stdio.h>
# include <conio.h>
# include <stdlib.h>

• Car Registration Number
• Car Make or Brand
• Car Model
• Car Colour (eg. Silver, Black , Red)
• Year of manufacturing (The year the car was manufacture)
• Engine Capacity (in cc)
• Transmission (manual or automatic)
• Cost of the car (SGD)
The Car Registration Number is in the format of AAA1234 or AA1234A or A1234A which is accordance to the Malaysia car registration format. The A alphabet is in accordance to the registration number for respective in Singapore. (eg. AEW9829 or W1212Y or MCD1177). Note the A and the 1234 total count in the registration number can be less than 3 like AT9829 or BHY280. The Car Make is for the identifying the manufacturer of the car like Honda, Toyota, Proton..etc. The Car Model is to represent the Manufacturers’ respective model like Honda City, Honda Civic, Honda Accord, Toyota Vios, Toyota Camry … etc.

Summary: 6 companies have a product in 5 different warehouses. Each company is identified by a positive ID number and each warehouse is identified by a number (1 for the first, 2 for the second,…)
Object: the object of this assignment is to write a C++ program which asks the user to enter a company ID number, and the number of products in each of the warehouses. It then computes and prints the total number of products for that company
If the total number of product is less than 100, it prints the message “place a new order”
Input: for each company, its ID, and the number of products in each warehouse with appropriate prompt messages.
Example: Enter company ID number: 101
Enter number of products in warehouse #1:30
Enter number of products in warehouse #2:60
Enter number of products in warehouse #3:0
Enter number of products in warehouse #4:5
Enter number of products in warehouse #5:27
The total for company 101 is:122
Output: for each company, the total number of product, and the message “place a new order” if the total number of product is less than 100.
Method:
1. Define global variable, int total_prod to hold the total number of products for a company
2. define the function void compute_total() that uses a loop to read the number of the products in all warehouses for one company, computer the total number of products and store it into the global variable total_prod.
3. Define the function void new_order() that determines if a new order need to be placed as follows: if the total number of products (in the global variable total_prod) is less than 100, it prints the message “place a new order”
4. Your function main does the following in a loop:
- read a company ID number
- call function compute_total() to read the number of the product in all warehouses for that company, and to compute their sum
- print the total number of the product for that company with an appropriate message
- call the function new_order() to determine if a new order need to be placed.
