How can you combine different c++ programs into one full software.

I am using the Code::blocks IDE

For — "combine different C++ programs" can mean two different things: create a single executable that contains all functionality, or ship a product that runs several independent executables together. and pointed toward those two directions; below are concrete, practical ways to implement each and common pitfalls to avoid.

If you want one executable: refactor reusable code into explicit modules and expose a stable API. Create a library project for shared logic, keep a single main() in the final launcher, and convert other program entry points into callable functions. Use namespaces and header-only or compiled libraries to avoid duplicate definitions. When providing runtime-loadable modules, use a small C-style entry point to avoid C++ name-mangling, for example:

extern "C" IModule* create_module();

If you want multiple executables to cooperate at runtime: build a controller/launcher that starts the programs, captures stdout/stderr, and provides a single UI or API surface. Choose a communication mechanism (local sockets, pipes, or a small REST/JSON protocol) and a serialization format. Add health checks and restart policies so child processes can be monitored and recovered.

Code::Blocks workflow tips: organize a project group (one project per library or executable), set project dependencies so libraries are built before the launcher, and keep consistent compiler/linker settings across projects. For larger codebases consider a meta-build like CMake and import the generated projects into Code::Blocks.

Watchouts: mixing debug/release runtimes, global/static initialization order, unresolved symbol collisions, and inconsistent compiler flags cause the most trouble. Add unit and integration tests, automated builds, and simple packaging to ensure the combined product is robust and maintainable.

If you want different programmes to communicate with each other when they're running at the same time, you need interprocess communication.

http://en.wikipedia.org/wiki/Interprocess_communication

If you actually mean different cpp files into one programme, you need to compile each cpp file into an object file and then link them together with the linker. If you're using Code::Blocks, you don't need to worry about that so long as you put all the cpp files into the same project.

Well you could create a process launcher.

If you include windows and shellapi you can ShellExecuteEx(SHELLEXECUTEINFO); More information about that is on the MSDN.

For seamless integration, you're going to find it extremely difficult unless they expose some kind of COM interop or have some API you can use.
