Compilation and linking

The translation process from C++ code to executable is called building, carried out in two stages:

1. compilation: production of an intermediate object file (.o) with unresolved external symbols
2. linking: resolve external symbols by reading code from standard and user-defined libraries

int getReturnValue(void);
int main() {
int ret = 0;
ret = getReturnValue();
return ret;
}

main: 0010 1101 ... getReturnValue
