I'm guessing you want to convert a string representation of a number into its equivalent form in which case atoi () is the recognized function to convert a character representation of a number into its integer equivalent.

The C language was developed specifically for use with unix. You will need to install gcc compiler if you don't already have it.

Yeah, it'll work under Unix. Try `man atoi` at your shell. Also, your title said to convert a char* to an int, which is what atoi() does. But your post said to convert a char, which is different. To convert a single char like '7', do this: int x = (int)ch - (int)'0';

Of course. Though, you will want to start a new thread with an appropriate subject line...
