C program for " If the marks obtained by a student in five different subject are input through the keyboard, find out the aggregate marks and percentage obtained by the student. Assume that the maximum that can be obtained by a student in each subject is 100."

Problem: C program for " If the marks obtained by a student in five different subject are input through the keyboard, find out the aggregate marks and percentage obtained by the student. Assume that the maximum that can be obtained by a student in each subject is 100."

Formulae used: 

Aggregate marks = sub1 + sub2 + sub3 + sub4 + sub5

Average marks = aggregate marks / 5

Percentage = ( aggregate marks x 100 ) / 500

C program:

// Program by shyam kanth

#include<stdio.h>

int main(){

    int sub1, sub2, sub3, sub4, sub5, sum;

    float avg, per;

    printf("Enter the marks of five subjects : ");

    scanf(" %d %d %d %d %d",&sub1,&sub2,&sub3,&sub4,&sub5);

    sum=sub1+sub2+sub3+sub4+sub5;

    avg=sum/5;

    per = (sum*100)/500;

    printf("Total marks obtained : %d\n",sum);

    printf("Averge marks : %.2f\n",avg);

    printf("Percentage scored : %.2f\n",per);

    return 0;

}
