Empty function in c++

Question

can anybody explain me that how empty function works in c++ with suitable example ?

Answer 1

The empty method in that code belongs to string class, the method returns a boolean; true when the string is of zero length (no content), and false otherwise. For better explanation of the empty method and string class see the reference:

What do you mean by "empty function"?
Functions with void type?

#include <iostream>

void foo(){
std::cout<<"test";
}

int main() {
foo();
return 0;
}
