Return Value:
Remarks:
Example:
#include <stdio.h>
#include <stdlib.h> /* for getenv
int main(void)
{
}
Output:
Cannot find environment variable INCLUDE
Calculates the absolute value of a long integer.
<stdlib.h>
long labs(long i);
i
Returns the absolute value of i.
A negative number is returned as positive; a positive number is
unchanged.
#include <stdio.h>
#include <stdlib.h> /* for labs
int main(void)
{
}
Output:
The absolute value of
The absolute value of -246834 is 246834
