Hi everyone.

Can someone give me an idea as how to insert text into the middle of a string in C or C++?

I want to implement a simple find and replace function, that searches a string for a specified substring, and replaces it with another which could be of a different length.

Im really scratching my head on this one

The string.h library has quite a few functions for dealing with strings - you can search strings for specific characters or even substrings, replace chars or substrings etc...
A description of all these functions is here.

The Standard Template Library is also a good source for such things... no need to reinvent the wheel.

Yeah man, just go with STL... that is what it is there for... you could spend at least a good week writing a good string class and functions that even come close to doing what STL's string class can.

OK thanks guys I'll have a look at STL.

check this link out, i believe this is what you are looking for
String Members

basically, it's a list of all the member functions and what they do for the string class. check out the "Insert" member.
