# WAP in C to Read Marks of a student in five subjects of a college and calculate his total of marks and also calculate percentage!

The Program in C to read marks of a student in five subjects of a college and calculate his total of marks and also calculate percentage is given below:

``````#include <stdio.h>

int main() {
int sub1, sub2, sub3, sub4, sub5, total;
float percentage;
printf("Enter marks of first subject: ");
scanf("%d", &sub1);
printf("Enter marks of second subject: ");
scanf("%d", &sub2);
printf("Enter marks of third subject: ");
scanf("%d", &sub3);
printf("Enter marks of fourth subject: ");
scanf("%d", &sub4);
printf("Enter marks of fifth subject: ");
scanf("%d", &sub5);
total = sub1 + sub2 + sub3 + sub4 + sub5;
percentage = (total / 500.0) * 100;
printf("Total marks: %d\n", total);
printf("Percentage: %.2f%%\n", percentage);
return 0;
}
``````

## Output:

Enter marks of first subject: 89
Enter marks of second subject: 88
Enter marks of third subject: 78
Enter marks of fourth subject: 56
Enter marks of fifth subject: 99
Total marks: 410
Percentage: 82.00%

## Pro-Tips💡

This program prompts the user to enter the marks of five subjects using scanf() function,

it then calculates the total of marks using the formula total = sub1 + sub2 + sub3 + sub4 + sub5 and calculates the percentage using the formula (total / 500.0) * 100, assuming full marks of each subject is 100.

Finally, it prints the total of marks and percentage using printf() function, where I have used %.2f to show the decimal point until 2 decimal places.

You can try different values of marks to see if it works fine.

Please note that this program does not check for the validity of the input, you may want to add some validation on the input to make sure that the input is a valid number.
