Dynamic source code in C++ [closed]

Answer 1

The real answer to your question is this:

extern "C" {
void function1 ();
void function2 ();
void function3 ();
}


 int main (int argv, char * argv [])
 {
     char * myString = new char [100];
     ...
     myString = "function1"; //user input     

     void (*f)() = dlsym(RTLD_NEXT, myString);
     f();
 }

You can obtain the function defined in your binary (by its name, if it was declared with extern "C"), and call it.

On windows, it becomes uglier, but still possible - read on GetProcAddress
