How do I cast a 5 character string in JavaScript?

First: char s; does not have enough space for a 5-character string; you need to account for the '\0' terminator. You can cast as you show (if compiled correctly) but you will be converting the address of the string to an int, not the value of the textual number in the string. There are various methods to do that, for example sscanf() and atoi().

Which data type is used to convert a string into an int?
