# Grade Calculator Using Switch

> Print a grade for a given mark using a switch statement.

## Problem Statement

Write a C program that takes marks as input and prints the corresponding grade using a switch statement.

| Marks    | Grade |
| -------- | ----- |
| 90–100   | A     |
| 80–89    | B     |
| 70–79    | C     |
| Below 70 | F     |

## Solution

```c theme={null}
#include <stdio.h>

int main() {
    int marks;
    scanf("%d", &marks);
    switch (marks / 10) {
        case 10:
        case 9:
            printf("Grade: A\n");
            break;
        case 8:
            printf("Grade: B\n");
            break;
        case 7:
            printf("Grade: C\n");
            break;
        default:
            printf("Grade: F\n");
    }
    return 0;
}
```
