SYNOPSIS
#include <stdlib.h>
arith_type _max(
arith_type expr1,
arith_type expr2);
PARAMETERS
arith_type Specifies the type of expr1, expr2, and the return value. Any arithmetic type can

#include <stdlibh>
.
#include <stdioh>
.
int main(void)
{
double r, x, y;
x = 5.0;
y = 7.0;
r = _max(x, y);
printf("The maximum number is %f.", r);
}
