Question

int (*ptFunction) (float,char,char);

char func(float,char,char);

If we use different return types as we did in above two function declaration, will the following assignment work correctly or will give compilation error??

ptFunction = &func;

Answer 1

The following code raise an error (in g++):

int (*pFun)(float, char, char);

char fun1(float, char, char) {}

int main() {

  pFun = &fun1; // error: invalid conversion from char (*)(float, char, char) to int (*)(float, char, char)

  return 0;
}
