Why if I write this code :

Question

#include <iostream>
using namespace std;

int main() {
int a;
cin>>a;
if (a='Hi'){
cout<<"Hi";
}
else {
cout<<"Norm";
}

return 0;
}

Answer 1

Use == instead of = in the if condition. = is used for assignment of variables while == to compare values.

Answer 2

If parameter should contains Boolean expression
As told by TurtleShell , you have to use == instead of =
a=="Hi" is a Boolean expression
a="Hi" is not

Answer 3

Why error?
