What OS are you using? While there are many ways to do this using C++, the ubiquitous command line tool "grep" is literally made for this.

[rubberman]

What Moschops said. Here is pseudo-code that you can use with C++ (or other programming language) to do this as well.

1. Open file
2. while not at end-of-file
3. read line
4. search for string (use strstr() in C/C++ for this).
5. if found in #4, increment counter.
6. goto #2.

Anyway, if you post some code we can help you sort it out.
