 # C Program to Calculate Total, Average, and Percentage of Five Subjects

C program to calculate total marks and percentage of five subjects; Through this tutorial, we will learn how to calculate total marks, average and percent of five subjects in c.

## Algorithm to Calculate Total, Average, and Percentage of Five Subjects Marks

Use the following algorithm to calculate write a program to calculate total marks and percentage of three subjects; as follows:

1. Read five subject marks and store them into variables.
2. Calculate sum of all subjects and store in `total = eng + phy + chem + math + comp`.
3. Divide sum of all subjects by total number of subject to find average i.e. `average = total / 5`.
4. Calculate percentage using `percentage = (total / 500) * 100`.
5. Finally, print resultant values totalaverage and percentage.

## C Program to Calculate Total, Average, and Percentage of Five Subjects

```/**
* C program to calculate total, average and percentage of five subjects
*/

#include <stdio.h>

int main()
{
float eng, phy, chem, math, comp;
float total, average, percentage;

/* Input marks of all five subjects */
printf("Enter marks of five subjects: :- ");
scanf("%f%f%f%f%f", &eng, &phy, &chem, &math, &comp);

/* Calculate total, average and percentage */
total = eng + phy + chem + math + comp;
average = total / 5.0;
percentage = (total / 500.0) * 100;

/* Print all results */
printf("Total marks = %.2f\n", total);
printf("Average marks = %.2f\n", average);
printf("Percentage = %.2f", percentage);

return 0;
}
```

The Output of the above c program; as follow:

```Enter marks of five subjects: :- 56 96 45 78 88
Total marks = 363.00
Average marks = 72.60
Percentage = 72.60```
