C/C++ :: Create Billing System Without Using Pointers - Array Calculations
Feb 17, 2014
I am trying to create an billing system "without using pointers". This is my class assignment. In this,
1) User inputs the name
2) The system asks how many items he has purchased
3) Displays a bill number [just a random number]
4) System asks for the item names the user purchased and stores them in an array (of max 10 (ten) inputs (or items))
5) After each item the user inputs, the system asks for the price of the item (stored in an array of numbers)
6) The total bill is calculated, by adding the sum of all prices in the array
I am having terrible difficulties in coding #4 and #5. Somehow, they aren't going well together. Here's what I have:
#include<stdio.h>
#include <stdlib.h>
int main() {
char item[10][10], answer = 'y', name;
int price[10], total_item, total_price = 0, i, j, a, total_bill = 0, max_items = 10, max_char = 10;
I have programmed a program for billing system. I have used parameters and arrays. All the functions are working except a one function. (Regular package function).
#include <iostream> #include <fstream> #include <string> #include <ctime> using namespace std; void main(int &minutes, int &minutesd,int &minutesn) {
The assignment is to create a program that displays the median of an array using pointers. Assume the array is already in ascending or descending order.I'm getting errors currently on the bottom two "return median;" statements.The code that I have so far is as follows...
#include <iostream> using namespace std; char again; int getMedian(int*, int); const int constant = 100;
int main() { int x = 1; char *y = (char *) &x; printf("%d ", *y); }
The output will be either "0" or "1" depending on the architecture of the system.When I executed on my system I got output as "1", now what is the architecture of my system is it 32 bit or 64 bit?
I know that the issue is around the array distance being of type double in the function get distance of type double. My question is how do i get around using the values from the distance array in the function to be used for calculations.
#include <stdio.h>/* initialization of preprocessor directives*/ #include <stdlib.h> #include <math.h> /*preprocessor directive in order to use sqrt function*/ int calcSecondsvar(int,int,int ,double); double getdistance(double,double,int,int,int);
[Code] ....
I forgot to mention that it keeps giving me the error cannot convert from 'double[8] to 'double' ....
I have an assignment to create a grading system using multimap. It's not completed yet at the moment but whenever i try to compile it tells me "no match for 'operator[]' in lines 56,57,etc. I
#include <iostream> #include <string> #include <map> using namespace std; class Student { public: //--- Constructor Student (int id = 0, double gpa = 0);
Create a payroll program to store and calculate the payroll for a small company with a maximum of 20 employees.
Program parameters are as follows:
1. Create a menu with the following options (use a do-while loop): A or a to add employee info D or d to display employee info T or t to display total payroll S or s to display the info of all employees Z or z to exit program
The information for each employee is: employee number, hours worked, pay rate per hour, tax deduction.
2. Use an array of doubles to store employee information.
3. Menu option A or a: ask the user for the employee information one value at . a time and store it in the array.
Please enter employee number: 2190 Please enter hours worked: 32.50 Please enter pay rate: 9.25 Please enter tax rate deduction: 5.50
4. Option D or d: ask the user for an employee number as integer and display . the information for the corresponding employee (cast the employee number
. in the array to integer and then compare). If employee number does not . match, output a msg. indicating "no such employee". If the employee number . is a match, output all the employee information stored in addition to the . calculated deduction and salary.
Output sample: Info for employee number: 2190 Hours worked: 32.50 Pay rate: $ 9.25 Tax deduction: 5.50 % Total pay: $ 284.89
5. Option T or t: calculate and output the sum of the total pay of all . employees.
6. Option S or s: display the information for all employees in the same . format as in option B.
7. Option Z or z: exit the program.
#include <stdio.h> #define MAX [20] int main(void) { int i; for (i=0;i<=20;i++) { char MenuOption=0; int EmployeeNumber;
So, the point of this program is to make simple billing program for a bakery. The program starts by having the cashier enter in the prices for single muffin, a half-dozen, and a dozen muffins. Then, the cashier enters in the amount that the customer wants. Based on the amount entered, the program will return the best offer. (For example, if the customer wants 11 muffins, but the price of 11 individual muffins is greater than the price of a dozen muffins, the program will recommend the customer by a dozen muffins). I'm having trouble getting my program to do the calculations correctly. I think my algorithm is correct, but it's not displaying properly.
#include <iostream> #include <iomanip> #include <cstring> using namespace std; class Bakery {
Community Hospital needs a program to compute and print a billing statement for each patient. Charges for each day are as follows:
a. room charges: private (P) room = $125.00; semi-private (S) room = $95.00; or ward (W) = $75.00 b. telephone charge = $1.75 c. television charge = $3.50
Write a program to get data from the keyboard, compute the patient’s bill, and print an appropriate statement. Typical input (nut yours do not have to be identical to this) is the following:
How many days was the room occupied? 5 What type of room? P Telephone used during the stay? N Television used during the stay? Y
Keep in mind that the user needs to know that the input can be any integer number of days for the length of stay, either (P, S, or W) for the room type, and either (Y or N) for both telephone and television options.
A statement (which yours MUST be identical to) for the data given follows:
Community Hospital Patient Billing Statement
Number of days in hospital: 5 Type of room: Private Room charge:$ 625.00 Telephone charge:$ 0.00 Television charge:$ 17.50
I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.
Code:
* Struct */ typedef struct {int *pArray; //the dynamic array int length; //the size of the dynamic array}Array; /* Function to create a dynamic array */ Array *initializeArray (int length) {int i; }
You are required develop a computerized GPA evaluation system of your class using array. The basic idea is to calculate the GPA (Grade Point Average) of each subject and then calculate the GPA of whole semester of all the students of the class and on the basis of that GPA calculate the grade and remarks of each student of the class. Suppose that the total students of the class are 50. Your system must also provide the facility of the following:
1.Searching a student result according to his/her roll number. 2.Updating the obtained marks of the students in case of any mistake in entering marks. 3.Display the result of student who is the topper of the class 4.Display the result of the student who got minimum CGPA out of the class. 5.Display how many number of students got greater than or equal to 3.0 CGPA. 6.Display how many number of students got greater than or equal to 2.00CGPA and less than 3.00. 7.Display the total number of students who got A grade in the semester. 8.Display the total number of students who got B grade in the semester. 9.Display the total number of students who got C grade in the semester. 10.Display the total number of students who got F grade in the semester.
Detailed Description: You are required to take the student’s marks for four subjects (Programming fundamentals, Calculus, English and Computing) as input from the user at runtime. After that calculate the GPA of each subject and the whole semester. Assume that total marks of a subject are 100 and each subject is of 3 credit hours except programming fundamentals. Programming fundamentals subject has 4 credit hours.
Complete Assessment system is given below in the table:
S.#Percentage (%)GradeGPARemarks 185-100A4Excellent 280-84A-3.75Very Good 375-79B+3.50Good 470-74B3.0Satisfactory 565-69C+2.50Above Average 660-64C2.0Average 755-59D+1.50Pass 850-54D1.0Just Pass 9Below 50F0Fail
Table: Assessment Scheme •Percentage of a subject = (obtained marks / total marks) * 100. Percentage works to find the grade of the student. •GPA of whole semester = multiply GPA of each subject according to the percentage of obtained marks by the number of credit hours for that course, sum up the GPA of all the subjects, and then divide this sum by the total number of credit hours taken in semester.
For example suppose the GPA in subject X is 2.5, in subject Y 2.6, and in subject Z is 3. Assuming that each subject is of 3 credit hours then GPA of whole semester will be calculated as: GPA= (3 * (2.5 + 2.6 + 3)) / 9 GPA= 2.7
On the basis of Semester GPA, you have to give grade and remarks to the student. You have to study the above table for other types of remarks according to grade.
•If a student has less than 50 marks in a subject, a message should display that “you have to repeat this subject “.
I have to develop a program that will analyse these time-sampled voltage and current measurements over 24 hours and find the total energy used, mean and peak power consumption and Energy used over each hour of the 24 hour period.
How do I go about doing this? I also have to use at least one integration method. The file data contains over 50 thousand lines in the format mentioned above.
I'm trying extremely hard to understand pointers and I have the basic concept down.. I feel as though my knowledge of dynamically allocated pointers and pointers in general is not enough to understand the logic behind what I'm trying to do. The problem is that the donations array must be able to accept any number of donations. I've made it do just that, but there is also an array of pointers which must each point to the same element in the donations array. The program works if I assign int *arrPtr[100] for example, but it does not work if I try to dynamically allocate it to accept the same number of elements for donations entered by the user. Here it's the snippet
#include <iostream> using namespace std; //Function Prototypes

I have to enhance my BMI program to tell whether the person is at optimal weight, under weight, or overweight and I cannot find the correct calculation. Here is the code I have so far that works for calculating the BMI.
namespace Body_Mass_Index { public partial class BMI_HW : Form { public BMI_HW() { InitializeComponent();
When you execute my code you'll notice the regular pay for the first example will calculate to $500 when it is only supposed to calculate to $400. I'm also having a problem adding up the totals of the regular pay and overtime pay to get a total payroll which is displayed in one cout statement. 95% of my code is correct, I'm just having these two issues. To make it more clear hear is my assignment:
The regular working hour for an employee is 40 hours a week. Sometimes employees work over time. When the employee works 40 or less hours, the regular pay is calculated as number of hours worked times the hourly rate. When the employee works over time i.e. beyond 40 hours then the employee's pay has two components a) regular pay (40 hours X hourly rate), and 2) overtime pay (the overtime hours beyond 40 X time and half of the hourly rate).
void compute(incomeInfo *ptrI, int count) { for (int i = 0; i<count; i++) if (ptrI->hours <= 40) { ptrI->regPay = ptrI->hours * ptrI->hRate; ptrI++;
My game runs in a while loop, as you can see in the code below. I need a timer, which won't stop this loop or freeze it, but it will wait, until timer is over and executes code without interfering with the while or for loop.
My plan is to make this a menu driven program, I have already got the program to give the answers but now I want it to give the user choices as well. The first step in this project is to add a menu to the program. The first menu the user sees should ask the user if the program will be taking input from a file or from the user directly via the keyboard. Regardless of option chosen, the user should then be prompted to specify whether a multiplication,subtraction or addition operation should be performed.
If the user originally chose the file input method then the program should proceed to display to the screen the results of those operations on each pair of data elements in the file and terminate. If the user chose to input via the keyboard then the user should be prompted to input the two numbers, perform the operation on those two numbers and display the results to the screen and ask the user which mathematical operation they would like to do next and continue in this manner until the user chooses to exit the program via a menu option. Fortunately the only file that needs to be edited are in.dat and complxcalc.cpp files.
I am trying to initialize an array of pointers to an array of characters, I can do it in 3 lines but I really want to do it in one line at the same time keeping the #define.
I need to create a program that continuously records data until the user enters '0'
The data that I read in is the student's last name, the year of the student (1-4), the major, the gpa, and the advisors name. I then need to print out how many students are in each year (1-4), the number of students each advisor has, the average gpa for each major, and so on. This is what I have, but I am stuck and think that I might be headed the wrong direction because the only thing working is the loop (not my gpa test calc).
//This program displays information pertaining to students #include <iostream> #include <string> using namespace std; int main () { int studYear; double average, studGpa; string studName, studMajor, studAdvisor, complete;
I have a 125X125 array, each element is 55 bits. The cache line for the CPU ( Cortex A9) is 32 bits. Is there anyway to do optimizations, like loop tiling that would make multiplication and calculations faster?
