Given Input:

Enter marks obtained in subject 1: 50
Enter marks obtained in subject 2: 60
Enter marks obtained in subject 3: 70
Enter marks obtained in subject 4: 80
Enter marks obtained in subject 5: 90

Expected Output:

Total marks obtained: 350.00
Percentage marks obtained: 70.00

Program:

#include <stdio.h>

int main()
{
    int marks1, marks2, marks3, marks4, marks5;
    float total, percentage;

    printf("Enter marks obtained in subject 1: ");
    scanf("%d", &marks1);

    printf("Enter marks obtained in subject 2: ");
    scanf("%d", &marks2);

    printf("Enter marks obtained in subject 3: ");
    scanf("%d", &marks3);

    printf("Enter marks obtained in subject 4: ");
    scanf("%d", &marks4);

    printf("Enter marks obtained in subject 5: ");
    scanf("%d", &marks5);

    total = marks1 + marks2 + marks3 + marks4 + marks5;
    percentage = (total/500) * 100;

    printf("Total marks obtained: %.2f\n", total);
    printf("Percentage marks obtained: %.2f\n", percentage);

    return 0;
}

Output:

Enter marks obtained in subject 1: 50
Enter marks obtained in subject 2: 60
Enter marks obtained in subject 3: 70
Enter marks obtained in subject 4: 80
Enter marks obtained in subject 5: 90
Total marks obtained: 350.00
