    Cool If_Else Problem

    /
    I'm a newbie and a senor citizen and to keep my mind alert I have decided to learn C++. However the following may be very simple for most of you, at least I thought it should be simple.

    The following piece of code will not compile. Any hints would be greatly appreciated.

    Code:
    #include <iostream>
    using namespace std;
    
    int main()
    {
        int A, B;
    	
        A = 6;
        B = 7;
    
        If( A == B )
        {
                 cout << "A is equal to B";
    	
         else
                 cout << "A is NOT equal to B";
         }	
         return 0;
    }

    You need cin.get(); above return 0; to keep the console from closing once it has displayed what it has to display. Otherwise you could run in from the command prompt.
    From C to shining C++!

    Great graphics, sounds, algorithms, AI, pathfinding, visual effects, cutscenes, etc., etc. do NOT make a good game.

    Code:
    #include <iostream>
    using namespace std;
    
    int main()
    {
        int A, B;
    	
        A = 6;
        B = 7;
    
        if( A == B )    // lower case 'if'
        {
                 cout << "A is equal to B";
        }
         else
        {
                 cout << "A is NOT equal to B";
        }	
         return 0;
    }
    I've amended your spelling of 'if'. C++ keywords are case-sensitive. I've aso added a couple of braces for clarity.
    Couldn't think of anything interesting, cool or funny - sorry.

    Thank you. I suspected it would be something simple. But I should have known better than to make the "I" in "if" upper case.

    >> I've aso added a couple of braces for clarity.
    Those braces are needed not just for clarity, but to get the program to compile. One statement follows the if, or a block of code inside braces. If you have an else, that should follow the statement or block of code, so the closing brace for the if block must come before the else. Similarly, the opening and closing braces for the else block should come after the else.

    Don't forget to post exact compiler errors you get when something isn't compiling.
