Write a C program to get the marks of 5 subjects and find the total and average

Description: Take the marks of 5 subjects as input. Print the total and the average.

Hint:

• Average is total / 5. Use float so the decimal part is not lost.

C program to find total and average marks

#include <stdio.h>

int main(void) {
    int m1, m2, m3, m4, m5, total;
    float average;

    printf("Enter marks of 5 subjects: ");
    scanf("%d %d %d %d %d", &m1, &m2, &m3, &m4, &m5);

    total = m1 + m2 + m3 + m4 + m5;
    average = total / 5.0f;

    printf("Total = %d\n", total);
    printf("Average = %.2f\n", average);
    return 0;
}

Output:

How it works

• The 5 values are read with one scanf().
• We divide by 5.0f (a float), so the result keeps its decimal part. With 5 the division would be an integer division.
