char to int

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.

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;
