atoi

[Lee125]

So...I know that the atoi function in the C++ standard library is supposed to convert a string into an integer...how does it work?...(I'm trying to learn stuff and I was just wondering)...if you could show me the code from it or make your own that would do the same task it'd be greatly appreciated...thanks in advance..

Even first link will show you basic atoi-like function http://www.geeksforgeeks.org/write-your-own-atoi/

Edit: implementation in libc:
