Well, your example is neither valid C-code, nor valid C++-code: - iostream belongs to C++, and not c - printf is declared in stdio.h, for C - you should use #include <iostream> instead of "iostream". With "", gcc searches only in the current directory (and in all directories given given as include directories on command line) - the filename should end on ".c" instead of ".cpp". ".cpp" is understood as C++-code by gcc - If you see nothing in the output: add a newlin "\n" to the printf-command - If you compile using "gcc", the compiler does not link to the C++-libraries. use "g++" instead. If you use (C-version, ola.c) #include <stdio.h> int main(){ printf("olare\n"); return 0; } it should work with gcc ola.c -o ola.exe. This also works with g++ ola.c -o ola.exe or as gc ola.cpp -o ola.exe if you want
As C++ version, I would propose (in ola.cpp): #include <iostream> int main(){ std::cout << "olare" << std::endl; } with g++ ola.cpp -o ola.exe The "best" programming environment depends on what you like - I'm using vim HTH, Axel
