**Pictorial Presentation:**

**Sample Solution:**

**C Code:**

```
#include<stdio.h>
#define N 10
// Function prototype declaration
int abs_val(int);
int main() {
int x, result;
// Prompt for user input
printf("Input a value (negative): \n");
scanf("%d", &x);
printf("Original value = %d", x);
// Call the abs_val function and store the result
result = abs_val(x);
// Output the result
printf("\nAbsolute value = %d", result);
return 0;
}
// Function to calculate the absolute value
int abs_val(int y) {
if(y < 0)
return(y * -1);
else
return(y);
}
```
