How can I delete all data from string (char array) in C lang? The typical way to do this is to set every character of the string to zero. The easiest way to do this is to use memset, assuming you know how much much valid memory the string has.
In C, the atoi() function converts a string to an integer.
input = Regex.Replace(input, "[^0-9]+", string.Empty);
