Answer 1

You need a to be of type char because you are reading a symbol.

Further, to compare, you need two equal signs (==), otherwise it is an assignment. And compare against a char symbol by putting the symbol in single quotes. Below you see an example. Try to extend it to the other operations as well.

char a;
cout << "answer \n";
cin >> a;
cin >> x;
cin >> y;
if ( a == '*' ){
z = x * y;
}
