    		strcat(str1,AY);
    
    
    	return *str1;
    }
    there is an C2143 error where it says i'm missing a ';' at line 87 and 88 and at line 90 is says input string is an undeclared indentifier...
    Please help with this! And if you're up to it, if you could look at the entire program to see if it makes sense, that would be greatly appreciated...
