Question

compilation error

#include <iostream>

int main() {

int a;
int b;
cin>> a >>endl;
cin>> b >>endl;
cout<<a<<endl;
cout<<b;

return 0;
}

Answer 1

Don't use "endl" with cin, doesn't work. And write it like this: cin>>a>>b;

Answer 2

No problem

Answer 3

Thx that was the problem 😘

Answer 4

endl is a defined value. But not variable.
it shouldn't be placed at cin <<

when you enter an integer into console. And press the "Enter" key. The buffer will be flushed to cin. endl is not necessary.
