i am using code::blocks with gcc compiler for windows. when i using your second program it gives me an error called "C:\\program is not recognized ......" . what is the reason?
There is No (.exe file) when i compile the program.
so for creating that (.exe) file what should i do. . ;
It is automatically created. Nothing to do. There must be one .exe (application) file in the compiled location
