C program to find the total and average mark of a student using arrays

Write a C program to find the total and average mark of a student using arrays.

  #include <stdio.h>
  #define MAXLIMIT 256

  int main() {
        int mark[MAXLIMIT], i, n, total = 0;
        float average;

        /* get the number of subjects from the user */
        printf("Enter the number of subjects:");
        scanf("%d", &n);


        /* get the marks for each subject from user */
        printf("Enter your marks:\n");
        for (i = 0; i < n; i++) {
                printf("Subject[%d]: ", i);
                scanf("%d", &mark[i]);
        }

        /* calculate the total */
        for (i = 0; i < n; i++) {
                total = total + mark[i];
        }

        /* find the average */
        average = (1.0 * total) / n;

        /* print the total and average */
        printf("Total: %d\n", total);
        printf("Average: %.3f\n", average);

        return 0;
}

  Output:
