C Programming (Turbo C++ Compiler) - Simple Student Grading Logic

---

I have given here a simple student grading by using if conditions and pointer assignment.

Source Code

---

#include <stdio.h>

 

int main()

{

    int i, arrMark[10];

    char *grade = 0;

 

    for(i = 0; i < 10; i++)

    {

        printf("Enter %d Student Mark: ", i  + 1);

        scanf("%d", &arrMark[i]);

    }

 

    printf("\n\nNo\tMark\tGrade\n");

    for(i = 0; i < 10; i++)

    {

        if(arrMark[i] > 100)

            grade = "Error";

        else if(arrMark[i] > 90)

            grade = "A+";

        else if(arrMark[i] > 70)

            grade = "B+";

        else if(arrMark[i] > 50)

            grade = "C+";

        else if(arrMark[i] > 30)

            grade = "C";

        else

            grade = "F";

        printf("%d\t%d\t%s\n", i + 1, arrMark[i], grade);

    }

    return 0;

}
