Thread: I have 2 Q's for you all

(1) It usually doesn't matter. Most thinks most make are hardly mission critical, so it really doesn't matter here. However, you've got two schools of thought:

(1a) Write readable code first and foremost. If it's clearer to use two statements, do so. If it looks better with a single call, go that route.

(1b) Write efficient code next. Ideally, your code won't be horribly inefficient from its initial design, so you won't really need to focus on optimizing it with questions such as the above. However, if you want to know, it's less overhead to do a single function call than it is to have two. So the second of the two would be better.

When in doubt, focus on readability.

(2) There are a few points I'll note at a glance:

(2a) Why the global variable?
int Answer = 0;

(2b) Never call 'main':

Code:

/* About the program */
int About( void )
{
    printf ( "\nRobinson's Quizzes -- 1.0\n\n"
             "Robinson's Quizzes was created by Daniel Robinson\n"
             "This program was made for my Year 12 Major Project.\n"
             "Please send any requests or bugs to {email addy}\n\n" );

    system ("PAUSE");
    main();
    return 1;
}

You are not able to do this with a C99 compiler. It is no longer valid. It's not a good idea anyway, because of the stack overhead you'll run into with recursion.

You call main in a bunch of functions. You should just be returning to the main function and continuing in your loop.

I think you mean.

Code:

printf("wang\nwang\n");

printf("wang\n" "wang\n"); won't work I wouldn't think.

I fixed your code tag. But no, both pieces of code are identical. The two strings will be concatenated as one. Since they are not seperated by a ',' in this instance, they are considered as a single argument. As such, like all strings like this, they're merged into a single string. The end result is both of those two printf statements are the same.
