C and C++ programming languages provide string or character to integer conversion with the atoi () function. atoi simply the short form of chArTOInteger where the uppercase letters stand side by side. The function is provided by the standard library which means we do not need to install an extra library or package. atoi () Function Syntax The function atoi is a C standard library function that converts strings to numbers (more specifically, integers). Each function returns the int value produced by interpreting the input characters as a number. The return value is 0 for atoi and _wtoi, if the input cannot be converted to a value of that type. In the case of overflow with large negative integral values, LONG_MIN is returned.

If no valid conversion exist for that string then it returns zero.

이 함수는 C 형식 문자열에서 비-공백 문자가 나오기 전 까지 최대한 많은 공백 문자 (' ', '\t', ') 들을 무시한다. 그 다음에 첫 번째 비-공백 문자부터 최대한 많은 숫자들을 C言語のatoi関数の使い方を解説しています。 atoi関数はstdlib.hをインクルードして使います。引数に数字の書かれた文字列を渡すとint型の整数にすることができます。 Note: atoi() function behaviour is undefined if converted integer underflows or overflows integer range. Use more robust and reliable strtol() function to convert string to integer. Example program to use atoi() function /** * C program to convert string to integer using atoi() library function. The atoi function converts string into an integer value. The input string must be a sequence of characters that can be interpreted as an integer. This function stops processing characters from string at the first one it cannot recognize as part of the number.
