return (0);


}

Your problem is in line 24, where you have the following statement...





cin %26gt;%26gt; "Side_two: " %26lt;%26lt; 2*m*n;





The cin statement can't take a value into a string "Side_two:". Make the cin statement point to a variable and all will be fine.
Reply:The person above is correct. I'm rusty on C++ but there is something wrong having a %26lt;%26lt; symbol in the cin statement:





cin %26gt;%26gt; "Side_two: " %26lt;%26lt; 2*m*n;





There should be a cout when using %26lt;%26lt;.
