PARAMETERS const char *str The function receives one parameter, a string. Note that the string is received as a constant - the function atoi will never alter a received string; only return its converted integer value. The atoi () function converts a character string to an integer value. The input string is a sequence of characters that can be interpreted as a numeric value of the specified return type. The function stops reading the input string at the first character that it cannot recognize as part of a number. This character can be the null character that atoi in c is a function that converts the given string to an integer.

Discards any whitespace characters until the first non-whitespace character is found, then takes as many characters as possible to form a valid integer number representation and converts them to an integer value. The valid integer value consists of the following atoi () will (should) not cause a stack overflow if the string contains characters other than digits. It will simply convert to an int any digit it finds from the beginning of the string until there is no more. int x = atoi ("12monkeys"); // x is 12 int y = atoi ("monkeys12"); // y is 0. You may check that there is no integer overflow (number atoi() Function to Convert a String to an Integer in C The atoi() function converts a string into an integer in the C programming language. 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.
