Answer:

Source: CoolInterview.com

atoi() This converts strings, like "23" or even "29dhjds" into integers (returning 23 and 29 respectively in this case).

atoi requires one char * argument and returns an int (not a float!).

If the string is empty, or first character isn't a number or a minus sign, then atoi returns 0.

If atoi encounters a non-number character, it returns the number formed up until that point. Source: CoolInterview.com

We use atoi() function to convert the charater into integer.
itoa() is used to convert integer to charecter.
