Is there a C equivalent to substr in perl or PHP? Something that might work 
like this: 

oldstring="Tony missed the clue bus.";
/* start at position 0, give me the next 4 chars as my string */
newstring=substr(oldstring, 0, 4); 

newstring would then contain the value "Tony". 

I tried writing my own, but am not succeeding. Attached is a simple program 
written for the purpose of writing my own substr function.

>From googling a bit, it appears C++ has such a function, but I'm trying to 
stick to C with this one. Am I missing the obvious?
