Here, we will write a C program to find the grade of a student using switch case statements. The below table shows the grading system.
Score in subject | Grade |
>=90 | A |
80-89 | B |
70-79 | C |
60-69 | D |
50-59 | E |
<50 | F |
Prerequisites for finding grade of a student using switch case statements:-
C program to find grade of a student using switch case statement
#include<stdio.h>
int main()
{
int score;
printf("Enter score( 0-100 ): ");
scanf("%d", &score);
switch( score / 10 )
{
case 10:
case 9:
printf("Grade: A");
break;
case 8:
printf("Grade: B");
break;
case 7:
printf("Grade: C");
break;
case 6:
printf("Grade: D");
break;
case 5:
printf("Grade: E");
break;
default:
printf("Grade: F");
break;
}
return 0;
}
Output for the test-case-1:-
Enter score( 0-100 ): 100
Grade: A
Output for the test-case-2:-
Enter score( 0-100 ): 95
Grade: A
Output for the test-case-3:-
Enter score( 0-100 ): 80
Grade: B
Enter score( 0-100 ): 50
Grade: E
Output for the test-case-5:-
Enter score( 0-100 ): 49
Grade: F
Enter score( 0-100 ): 30
Grade: F
The condition of the switch case is score/10, so, the score every is divided by 10 and the matched label will be executed. For score 90-100 is A, so for labels 9 and 10, the grade will be A. Similarly, for other ranges. If the score is below 50 then score/10 gives below 5 and it doesn’t match with any condition hence, the default statement will be executed.
Using nested if-else statement
The same program also can be written using nested if-else statements. Here in every condition, the score will be compared.
#include<stdio.h>
int main()
{
int score;
printf("Enter score( 0-100 ): ");
scanf("%d",&score);
if(score>=90 && score<=100)
printf("Grade: A");
else if(score>=80)
printf("Grade: B");
else if(score>=70)
printf("Grade: C");
else if(score>=60)
printf("Grade: D");
else if(score>=50)
printf("Grade: E");
else
printf("Grade: F");
return 0;
}

Similar C programming examples on if-else and switch-case statements
Switch case…When I input 101-109, it becomes A. Likewise, when I input negative numbers, it becomes F instead of the default Error message. This is my grading scale:
A = 90 -100, B = 80-89, C = 70 -79, D = 60 – 69, and F = 0 -59.
Please do help I’m a beginner. Appreciate it!
In that case, you need to handle the case when the input value is greater than 100 and less than 0. If the input value is greater than 100 or negative then we should display “invalid input”. See the below program:-
Please can there be multiple switches in the C program? I have been trying to add another switch operation, but the program keeps returning to zero after the first switch statement is executed.
Yes, there can be multiple switches in a C program or we can use the switch inside the switch statement.
Nice
