Question

I need a C++ command that reads in a single integer from cin. If the number is 7 , outpur "Lucky" if not output nothing.

Not even sure what he's asking me to do?
HELP?!

Answer 1

You need to use the conditional operator in C++.
cin >> a; // a is the integer you get from input
(a == 7)?cout<<"lucky" : cout<<"";

Answer 2

#include <iostream>

using namespace std;

int main()
{
int number;
cout <<"Enter a number "<<endl;
cin>> number ;

if (number==7){

cout<< "Lucky" <<endl;
}


return 0;
}
