atoi
Syntax: #include <stdlib.h> int atoi( const char *str ); 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. For example, i = atoi( "512.035" ); would result in i being set to 512. You can use (Standard C I/O) sprintf() to convert a number into a string. Related topics:
