The only reason I see for using a pointer, is if you intend to use a buffer to store all the factorials found. The rest of this section is written with that in mind. The error is extremely obvious - to any slightly trained eye. long *result; // Points where? *result = 1; // Writes to arbitrary, uncontrolled location. The best that can happen is a crash.

Argh... I intended to add a new reply to my old one, but ended up editing it instead, so it made little sense. Stand by.

When your main() calls setvalue(5); that's totally unrelated to the code you wrote above it. You need to create a classname object to run it on. Btw, dev-cpp uses an ancient compiler that you really shouldn't be using, at least as a beginner.

See http://www.cppreference.com/wiki/st.../random_shuf fle For example, if you have them in a vector<int> v; then the line random_shuffle(v.begin(),v.end()); will do that.
