Copying char array to integer

Question:
I have a char array, for example: char orig_amt [20]. I need to convert this to an int orig_amt so I can do some calculation. Is there a command to change a char array to int?

Answer:
The standard C library provides the atoi function, which converts an ASCII string to an integer.

nOrig_amt = atoi(szOrig_amt);
