Kто нибудь понимает как это работает ?

Question

#include <iostream>
#include <cmath>
using namespace std;

struct S
{
S(){print('s');}
void print(char c){
cout<<c;
}
}A;
int main()
{
S a;
a.print('I'); //Output ssI
}

Answer 1

The struct variable A.
Prints the first 's''

S a; prints the second 's'
a.print. prints the I

Actually when having a struct variable like 'A' you do not need to declare the struct.

A.print('B');

Will print sB

Having a struct variable is optional.
