Write a C program to calculate Grades.
int main() {
int marks[5], average, total = 0, grade, i;
/* input marks from the user */
printf("Enter your five subject marks:\n");
for (i = 0; i < 5; i++) {
printf("Enter Mark for Subject %d: ", i + 1);
scanf("%d", &marks[i]);
}
/* find the total marks */
for (i = 0; i < 5; i++) {
total = total + marks[i];
}
/* calculate the average */
average = total / 5;
/* find the grade */
if (average > 95) {
grade = 'S';
} else if (average > 90) {
grade = 'A';
} else if (average > 80) {
grade = 'B';
} else if (average > 70) {
grade = 'C';
} else {
grade = 'D';
}
/* print the outputs */
printf("Total Marks: %d\n", total);
printf("Average : %d\n", average);
printf("Grade : %c\n", grade);
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
