atoi()
Syntax:
#include <stdlib.h>
int atoi( const char *str );
Description:
The atoi() function converts str into an integer, and returns that integer. str should start with some sort of number, and atoi() will stop reading from str as soon as a non-numerical character has been read.
Example:
i = atoi( "512.035" );
RESULT: i set to 512.
