    Hi,
    Can any one please tell me what is the best way to convert a char to an int. I can not seem to find any build in function to do the job. Thanks in advance.

    char to int

    Use atoi() from <stdlib.h>.

    char Words[]="123";
    int Number;
    Number = atoi(Words);

    atoi() will return 0 if any character is not a digit

    for a single char you can do it like this:

    char letter = 'a';
    int number = (int)letter;
