whats wrong with this code!

Question

just started learning if statements and decided to test it. I made a simple 2 question quiz. but no matter what the answer is it always says correct. thanks in advance!

#include <iostream>
using namespace std;

int main()
{
cout<<"Welcome to history pop quiz"<<"\n first question"<<"\n when did world war 1 happen?\n";
int q1,q2,a,b;
cin>>q1;
if (q1=1914){
cout<<"correct!";
a=1;
}
else{
cout<<"wrong!";
a=0;
}
cout<<"next question"<<"\n when did world war 2 happen? \n";
cin>>q2;

if (q2=1939){
cout<<"correct! \n";
b=a+1;
}
else{
cout<<"wrong! \n";
b=a+0;
}
cout<<"you scored "<<b;

}

Answer 1

if (q1 == 1914)
if (q2 == 1939)
= is assignment like i assign variable age as 13 so age = 13 but to compare u use == is age equal to 13?

Answer 2

thanks. don't know how i missed that!
