c++ - Call a function before main -


possible duplicate:
is main() start of c++ program?

is possible call function before program's startup? how can work in c++ or c?

you can have global variable or static class member.

1) static class member

//beforemain.h class beforemain {     static bool foo; };  //beforemain.cpp #include "beforemain.h" bool beforemain::foo = foo();

2) global variable

bool b = foo(); int main() { }
