|Information for free function indexOf()|
|Function||indexOf(string str, string find, int offset)|
|API||Attacking, Banking, FTP, Watch, HTTP, Challenges, Hacktendo|
|Description||Returns the position of 'find' in the 'str' string, starting from the nth character which is also know as the offset.|
If 'find' is not found in 'str' indexOf() returns -1.
The third parameter and the returned value start counting with 0 as the the first character of a string.
The following Challenge example will return the index of the comma in "Hello, world". Although the comma is the sixth character indexOf() returns 5 because it starts counting with 0.
string lineStr = "Hello, world."; int linePos = indexOf(lineStr, ",", 0); setOutputInt(linePos);
