After coming back to C++ after awhile, and clicked on codeblocks. I noticed something odd hapenning. When I click on main.cpp to start coding, it says that it could not open main.cpp and that it does not exist. Even making a new hello world program, it continues the same problem?
I din't understand your problem clearly.I think mingw c++ compiler may not linked with codeblocks.Check the size of installation file of codeblocks ,if size is more than 70mb than mingw is already linked otherthan not.
