while ( 1 ) { cin>>num; if ( num == correct_num ) break; } here correct_num is variable on which the correct value is assigned already

It is wrong. the cin>>num; needs to be in the do while loop.

#include <iostream> using namespace std; int main() { int num; cin>>num; do { cout<<"enter again"; } while(num != num); return 0; } correct me if this is wrong. thanks

And the num != num is wrong too. the second num needs to be an other variabele or a value.
