Compiler Warning (level 1) C4551

function call missing argument list

A function call must include the open and close parentheses after the function name even if the function takes no parameters.

The following sample generates C4551:

// C4551.cpp
// compile with: /W1
void function1() {
}

int main() {
   function1;   // C4551
   function1();   // OK
}
