Pictorial Presentation:
Sample Solution:
C Code:
#include<stdio.h>
#define N 10
int main()
{
int uabs(int), x, result;
printf("Input a value (negative): \n");
scanf("%d", &x);
printf("Original value = %d", x);
result= abs_val(x);
printf("\nAbsolute value = %d", result);
return 0;
}
abs_val(int y)
{
if(y<0)
return(y*-1);
else
return(y);
}
Sample Output:
Input a value (negative): Original value = -253 Absolute value = 253

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
