Question

Kindly assist me with making a single loop out of these four 'if' statement blocks.
They're in the 'void room(room *room)' function.

Here's the link to the code: http://txt.do/dbyw

Thank you!

Answer 1

A simple change would be to go to if/ else if / else statement, but the switch statement is used for n-way branches.

Answer 2

I'm sorry, I don't understand. How does the if/else help with making it a single loop? Why did you mention the switch statement concept? n-way branching: number of switch statements involve? Do you have anything in particular I could read?

Thanks.

Answer 3

My C is super rusty, but I think something like this should work:

char *directions[4] = ["North \t", "South \t", "West \t", "East \t"];
for (i = 0; i < 4; i++) {
if(room->neighbors[i] != NULL) {
cout << directions[i];
}
}

or something to that extent...
