4. A1) No, it counts only white spaces in the beginning of line (white spaces in standard isspace () implementation are ' ', '\t', '\n', '\v', '\f', '\r'; i.e. space, tabs, newline, feed and carriage return). A2) Yes, it determines sign of value. A3) If value is "234" it will not increment i. But if value is "+234" or "-234" we need to.

The atoi () function converts a string into an integer in the C programming language. atoi () stands for ASCII to Integer. The atoi () function neglects all white spaces at the beginning of the string, converts the characters after the white spaces, and then stops when it reaches the first non-number character.

C programming string to int C Program to Convert String to Integer

The atoi () function converts an integer value from a string of characters. The input string is a character string that may be turned into a return type numeric value. The function stops reading the input string when it encounters the first character that it does not consider part of a number. It may be the null character at the string ends.
