Sorry, this is correct code.

using namespace std;
cout <> nX;
cout << “You entered ” << nX << endl;

using namespace std;
cout <> nY;
cout << “You entered ” << nY < nY)
cout << nX << ” is greater than ” << nY << endl;
else if (nX < nY)
cout << nX << ” is less than ” << nY << endl;
else if (nX = nY)
cout << nX << ” is equal to ” << nY << endl;

I’m trying to write a code, in which the user will enter a number, enter another number than write whether the 1st number was greater than, less than, or equal to, the 2nd number number. All numbers work, except when the 1st and 2nd numbers are both 0. In that case, it says nothing. My code is below; can you see the problem?

using namespace std;
cout <> nX;
cout << “You entered ” << nX << endl;

First off, = is for assignment, not comparison. You would normally use == to do comparisons, except == doesn’t work on string literals (which is anything inside double quotes). Probably the best way is to declare your a variable as a std::string instead of a char. Then it will work as you expect. This is covered in lesson 6.6.

Hi, great website btw!
However, whenever i try to use a char variable in an if statement (e.g :

if(a = “Hello”)
cout << “Hello there”;

it does not compile correctly.

can anyone help? if so please email me on fight.the.purple@hotmail.co.uk or leave a comment
