USING C PROGRAMMING

***CODE MUST BE MODULARIZED**

Instructions: Create a program that will collect multiple receipts from multiple classrooms to accumulate total cookie sales.   Once all receipts have been processed, the program must show what classroom is won and the total amount of cookies they sold.

The classrooms that are participating are from the:

                2^nd Floor: 201, 202, 203, 204, 205, 206, 207, 208

                3^rd Floor: 301,302, 303, 304, 305, 306, 307, 308, 309

                4^th Floor: 401, 402, 403, 404, 408, 409, 410

In total 24 classrooms.

Instructions for writing the program:

1. The program requires parallel arrays to complete.
2. You can populate the array either by allowing the user to enter the classroom numbers or by hard coding the classroom numbers in your array.
3. The program will then take in each receipt that was submitted by each classroom. Each classroom can have 1 or more receipt. Each receipt represent a cookie sale. For example, in classroom 401 a student sold 10 boxes of cookies.    The program should ask for the classroom and then the cookie sold.  
4. The cookies sold for each entry must be accumulated per classroom.
5. Once all receipts have been processed, the winning classroom and total must be displayed.
6. The program must be written in C….and it must be modularized.

Answer 1

C code:

#include <stdio.h>

#define SIZE 24

// Function to return index of maximum value in the array
int findMaxIndex(int arr[], int n) {
    int idx = 0;
    for (int i = 0; i < n; i++) {
        if (arr[idx] < arr[i]) {
            idx = i;
        }
    }
    return idx;
}

// Function to return index of given classroom
int findClassroomIndex(int arr[], int n, int classroom) {
    for (int i = 0; i < n; i++) {
        if (arr[i] == classroom) {
            return i;
        }
    }
    return -1;  // Classroom not found
}

int main() {
    // Hard coded parallel arrays
    int classrooms[SIZE] = {201, 202, 203, 204, 205, 206, 207, 208, 301, 302, 303, 304, 305, 306, 307, 308, 309, 401, 402, 403, 404, 408, 409, 410};
    int cookiesSold[SIZE] = {0};
    int classroom, classroomIdx, cookies;
    // Get the classroom number
    printf("Enter a classroom number or -1 to exit: ");
    scanf("%d", &classroom);
    // Keep asking for classroom number till user enters -1
    while (classroom != -1) {
        // Find the index of classroom number
        classroomIdx = findClassroomIndex(classrooms, SIZE, classroom);
        // Get the number of cookies sold
        printf("Enter the number of cookies sold: ");
        scanf("%d", &cookies);
        // Add cookies sold to the corresponding classroom
        cookiesSold[classroomIdx] += cookies;
        // Get the classroom number
        printf("Enter a classroom number or -1 to exit: ");
        scanf("%d", &classroom);
    }
    // Find the index of classroom that sold the maximum cookies
    int maxIdx = findMaxIndex(cookiesSold, SIZE);
    int winningClassroom = classrooms[maxIdx];
    int totalCookies = cookiesSold[maxIdx];
    // Display the winning classroom
    printf("Class number %d won and sold a total of %d cookies\n", winningClassroom, totalCookies);
    return 0;
}
