C program to enter student marks and find percentage and grade using conditional operator



#include <stdio.h>

int main()
{
    int phy, chem, bio, math, comp;
    float per;

    printf("Enter phy subjects marks: ");
    scanf("%d", &phy);
    printf("Enter chem subjects marks: ");
    scanf("%d", &chem);
    printf("Enter bio subjects marks: ");
    scanf("%d", &bio);
    printf("Enter math subjects marks: ");
    scanf("%d", &math);
    printf("Enter comp subjects marks: ");
    scanf("%d", &comp);

    per = (phy + chem + bio + math + comp) / 5.0;

    printf("Percentage of marks = %.2f\n", per);

    (per >= 90)?
        printf("Grade A"):
    (per >= 80)?
        printf("Grade B"):
    (per >= 70)?
        printf("Grade C"):
    (per >= 60)?
        printf("Grade D"):
    (per >= 40)?
        printf("Grade E"):
        printf("Grade F");


    return 0;
}


Output:
Enter phy subjects marks: 89
Enter chem subjects marks: 96
Enter bio subjects marks: 57
Enter math subjects marks: 48
Enter comp subjects marks: 75

Percentage of marks = 73.00
