how can I convert a string into a int?

[hoggle]

I want to turn my string into an int.
also the string will always contain a valid integer.

thanks

use the [tt]atoi()[/tt] and [tt]atol()[/tt] functions:

[tt]
char str[100] = "12345";

int i = atoi(str);

// i now equals 12345
[/tt]

if you are using the String class (not a character array) you need to use the following:

String str = "12345";
int i = atoi(str.c_str());
