C++ :: Create A Program That Reads Numbers And Calculate Them On A Separated Subroutine
Nov 15, 2013
I need to create a program that reads some numbers, and calculate them on a separated subroutine, and the return of this subroutine must be the sum of all the numbers. I'm getting an error but I can't figure out why =/
#include <iostream>
using namespace std;
int calc(int val, int qtd){
int sum=0;
for (int cont=0; cont<qtd; cont++)
sum=sum+val;
return sum;
[Code]...
The error that I'm getting is on the line 22.
The error message: "invalid conversion from 'int*' to 'int' [fpermissive]

Write a program that reads in ten whole numbers and that output the sum of all the numbers greater than zero, the sum of all the numbers less than zero (which will be a negative number or zero), and the sum of all the numbers, whether positive, negative, or zero. The user enters the ten numbers just once each and the user can enter them in any order.
Your program should not ask the user to enter the positive numbers and the negative numbers separately. Assume the user will type integer numbers.
this is what i got but it wont run saying there is an error
#include<iostream>;
using namespace std;
int main() {
int count=0;
int num;
int positive=0;
int negative=0;

Here is my code and basically these are the steps. I feel like we have something good to work on but we keep getting errors.
a. Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file.
b. Save the output of the program in a file.
c. Modify the function getNumber so that it reads a number from the input file (opened in the function main), outputs the number to the output file (opened in the function main), and sends
the number read to the function main. Print only 10 numbers per line.
d. Have the program find the sum and average of the numbers.
e. Modify the function printResult so that it outputs the final results to the output file (opened in the function main). Other than outputting the appropriate counts, this new definition of the function printResult should also output the sum and average of the numbers.

Can we use more than one 'if' subroutine in one program. I am trying to implement this but if I run the two subroutines at the same time the lower subroutine directly shows "invalid grade". But if I run one at a time then they work perfectly fine.
Why is this happening? Does the compiler think that its the same "if" routine. If so how do I segregate it???
Code:
printf("Enter a score:");
scanf("%d",&gr);
if(gr>=80 && gr<=100)
printf("A Grade
");
if (gr>=60 && gr<80)
printf("B Grade

So im trying to create a program that will calculate a shipping cost. I'm stuck on trying to calculate the actual milage and cost. Example being 1400 miles for a 2lb package would be $2 for every 500miles. so it would cost $6. But Im having trouble getting the program to round up the 1400 to 1500 so it charges the correct amount.
I know there would have to be a way to do this without programming all the conditions.
Also the course has not reached loops yet.
Code:
// This program will calculate the shipping charges.// The shipping rates are based on per 500 miles shipped.
// They are not pro-rated, i.e., 600 miles is the same rate as 900 miles or 1000 miles.

#include <stdlib.h>

I am using codeblocks for school and I am trying to create a program to calculate a percentage for commission and a bonus. I have tried using a decimal for percentage, int and floats with casting. Every time it I try it displays 0 or just the bonus. I even took and did a test page. My head is about to pop.
Write an algorithm that can be used to calculate the commission earned in a real estate transaction. The chart below describes the formulas used to calculate the commission.
Sales Price Commission
Less than $100,000 5% of Sales Price
$100,000 to $300,000 $5,000 + 10% of Sales Price over $100,000
More than $300,000 $25,000 + 15% of Sales Price over $300,000
// Commission and Bonuses.

I'm trying to create a program to calculate the flight time and fuel burn of an airplane. However when I repeated the whole calculation, it did not show any data or result like the previous calculation. In addition, the "If" statement that I used to test the "fuelRemain" doesn't work properly. I can't figure out why.
Here are the outputs [URL]

I have been working on a program to calculate the factorial of numbers. Part of my code is copied and modified from the FAQ about validating numbers in user input.
I have encountered a problem with the for loop that I am using near the end of my code. No matter what I do, it seems that my loop only does the multiplication of b = a*(a-1) and then prints. For example, inputting 5 will result in a print of 20, but the factorial is 120.
Code:
int main(void) {
char buf[BUFSIZ];
char *p;
long int a;
long int b;
long int i;
printf ("Enter a number to be factorialized: ");

I just wrote a code that reads in a text file called "policies.txt" which looks like this:
Pol1 M N 20 100000 1 .04 99
Pol2 F S 30 100000 1 .05 99
Pol3 M S 72 750000 1 .03 99
Pol4 F N 45 1000000 1 .05 99
This works perfectly fine, but what if I want each element of the table to be separated by commas. For example:
Pol1,M,N,20,100000,1,.04,99
Pol2,F,S,30,100000,1,.05,99
Pol3,M,S,72,750000,1,.03,99
Pol4,F,N,45,1000000,1,.05,99
or better yet, what if I want it to not matter whether the columns are separated by commas or spaces? is there any way to do this? If there is no way to read in both comma-separated and space-separated elements simultaneously then I would prefer just comma, rather than the space separated which my code is able to read now. What modifications would I have to make to my code to make this work? This is my code to reference.
double ratesmn[86] = {
#include "MaleNonSmoker.txt"
- 1
};
double ratesms[86] = {
#include "MaleSmoker.txt"

Write a program that prompts the user to enter three integer values, and then outputs the values in numerical sequence separated by commas.
So, if the user enters the values 10 4 6, the output should be 4, 6, 10.
If two values are the same, they should just be ordered together.
So, the input 4 5 4 should give 4, 4, 5.
Code:
#include "std_lib_facilities.h"
int main()
{
cout << "Enter three integers, separated by space: ";
int a, b, c, temp1 = 0, temp2 = 0;
cin >> a >> b >> c;
[Code] ....
My first solution has a bug, so here's the corrected solution, written using only features I have learned in the first three chapters:
Code:
#include "std_lib_facilities.h"
int main()
{
cout << "Enter three words, separated by space: ";
string a, b, c, temp;
cin >> a >> b >> c;

I am attempting to read in a file that has 4128 sets of 21 numbers separated by commas and write it into an array. I now know that in order to use fseek, I have to make my array a character array, but I need my function to read in decimals (ex: 0.172635). I'm reading in
0.102598,0.000000,0.000000,0.000000,0.000000,0.307 793,0.000000,0.410391,0.102598,0.000000,0.102598,0 .102598,0.000000,0.000000,0.102598,0.102598,0.8207 83,0.000000,0.000000,0.000000,0.000000
and keep getting numbers like 48 49 50.
Code:
void CSread(char filename[100], char array[22], char array2[22], unsigned int arraysize)
{
char genename[32];
double temp = 0;
FILE *CSfile;
CSfile = fopen(filename, "r");
");

Write a program that calculates the average of a stream of positive numbers. The user can enter as many positive numbers as they want, and they will indicate that they are finished by entering a negative number. For this program, treat zero as a positive number, i.e., zero counts as a number that goes into the average. Of course, the negative number should not be part of the average. You must use a function to read in the numbers, keep track of the running sum and count, compute the average, and return the average to the main() function. Note that you must use a loop to do this, as you don't know how many numbers the user will enter ahead of time. I am having problem writing a loop program for it..

Question is : Write a program that opens a file and counts the whitespace-separated words in that file.?
my answer is :
#include <iostream>
using namespace std;
#include <iostream>
#include <string>
#include <fstream>
int main() {
string filename = "Question 1.cpp"; // File name goes in here
[Code] ....
Now I am not sure if im suppose to get a msg saying : The file "Question 1.cpp" has 0 words.
im wondering is the question that im being asked, asking me to input a string of words and then the compiler when it builds and runs the program counts the word spaces.?

Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.
For example, if the number is 2339 the program should print
9 *********
3 ***
3 ***
2 **
So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!
My code so far:
int main() {
int n;
printf("number? ");
scanf("%d", &n);
while (n > 0) {
printf("
%d

I started to write a program that repeatedly reads in values for a,b and c and find the root of the polynomial
ax^2 + bx + c = 0
The program should print out for example:
two complex roots: root1 = -1.00000 + i*1.41421
root2 = -1.00000 - i*1.41421
My code:
#include <stdio.h>
#include <math.h>
int main(void){
int a,b,c;
printf("Choose the values of a, b and c for the equation ax^2 + bx + c");
scanf("%d%d%d
",a,b,c);

I've been working on a program that displays the number of digits in each line of a file, but I feel stuck. Take for example a file that contains these characters:
6347aaa9
54j
811111
6a
709
And I'm trying to display a result like this
1 //that's the number of the line 5 //the number of digits
2 2
3 6
4 1
5 3
Here's what I've written so far:
Code:
#include<stdio.h>
int main() {
char a=0;
int number_of_digits=0, linescount=0, num, number_of_digits_per_line=0;
FILE *inputFile;
if(!(inputFile=fopen("C:TestTest.txt","r")))
[Code]..
I also thought of using fgets and strlen but I am not very good with them and couldn't get the program to work correctly. It did work but it displayed all characters, letters included, not only digits.

Write a program that reads data from a file (use the attached data file). These data are a student name and 3 test scores. The program should calculate the average of the 3 test scores, and display the name, 3 test scores, and the average to the monitor.
Useful tips:
a) Include the following header files: iostream, fstream, iomanip, and string
b) The name of the data file is “datafile.txt”, you need to save the file in the same folder of the source file.
c) use the manipulators (setw, setprecision, setfill, showpoint, fixed) to format the average with 1 digits after decimal point as following.
d) Use character ‘ ’ for tab.

c++ program that reads in a sequence of binary digits (values 0 and 1) and stores them into a STL container. The input should terminate on any input that is not a 0 or 1. After finishing the read-process, apply a "bit-stuffing" algorithm to the container. In this case the bit stuffing should occur after four consecutive bits of the same value.i,e. four 0's or four 1's.. Also write the de-stuffing code to process the stuffed data to recreate the original data and verify that the original data is recovered correctly.

Write a test program that reads a 3-by-4 matrix and displays the sum of each column. here is a sample run:
Enter a 3-by-4 matrix row by row:
1.5 2 3 4
5.5 6 7 8
9.5 1 3 1
