    Angry can't figure out simple program

    hi, can someone please tell me why this won't compile? errors are improper typedef 'test', statment mising ; and expression syntax. thanks so much

    Code:
    #include <iostream.h>
    #define tab '\t'
    
    struct test{
    		char name;
    		int value;
    		};	
    
    ostream& operator<<(ostream& oput, test& t)
    {
    	oput<<t.name<<tab;
    	oput<<t.value<<tab<<endl;
    	return(oput);
    };
    
    main()
    {
    	test try={"a",1};
    	cout<<try;
    	return(0);
    }

    Lightbulb I think...

    I think it's just supposed to be:

    struct test{
    char name;
    int value;
    } // without the ;

    A simple error blight, but somewhat easy to miss if you don't know C++ style try..throw..catch exception handling.

    try is a keyword.

    It is the same problem you would have with a variable called for or do.

    Also, a smaller but critical error, when you define an overloaded operator you are defining a function. So don't put a semicolon after the declaration.

    One last error, you are assigning "a" (which is a const char*) to a variable of type char without a cast. You will need to change the quotes to single quotes.

    So:

    1: Change try to something else
    2: No semicolon after operator<< declaration
    3: Single quotes around the a

    thanks, as you can see i'm new at this . . . i was taught to put the ; after overloads, it works either way so i was wondering why it's a critical error? thanks again
