help with a function

[massimo84]

Is there a command which it finds the maximum of numbers? like MAX(A,B) in fortran

No, but you would write one pretty easily. See here: http://cboard.cprogramming.com/showthread.php?t=96236

Actually, I'm pretty sure there is a macro somewhere in a standard header that does MAX(a, b) of integer/float vaues.

You can do this as a macro or as a function. There are downsides to both. The macro will evaluate its arguments multiple times. The function has call overhead. Two versions

#define MY_MAX(a, b) ((a)>=(b)?(a):(b))

int my_max(int a, int b)
{
    return a>=b?a:b;
}

The best of both worlds is an inline function, if your compiler supports it. It is usually a bad idea to name a macro "MAX" or "MIN", since many system headers on various platforms define these macros themselves.
