    Can't get a variable to be put in memory (or however that's supposed to be phrased)

    For the variable pettoremove, I can't get the scanf to work and the program doesn't work if I don't preset pettoremove a number. That number never changes, and I don't know why and I can't make it work. Is it because it's in a look, I have to use pointers somehow?

    Code:
    void deletepet(pet petarray[], int numberofpets)
    {
    	int pettoremove=9;
    	int validentry=0;
    	while (validentry==0)
    	{
    		printf("Enter the number of the pet you want to remove from the archive: ");
    		fflush(stdin);
    		scanf("&d", &pettoremove);
    		printf("%d\n", pettoremove);
    		printf("%d\n", numberofpets);
    		if (pettoremove<=numberofpets)
    		{
    			printf("That's totally a valid entry\n");
    			validentry=1;
    		}
    		else
    		{
    			printf("That's not a valid entry\n");
    		}
    	}
    	printf("So I made sure bad stuff won't happen, now CODE MOAR STUFF HERE\n");
    }

    1) Congrats for posting in CODE tags. However, please post compilable code. A main(), includes, etc.
    2) When you compile, do you have warnings turned on? I don't think so. Do that. You'd see immediately that
    Code:
    scanf("&d", &pettoremove);
    has a problem.

    K, I found the problem. %d instead of &d. I do have warnings turned on, but I didn't realize I had made a mistake until you pointed it out, so thanks.

    If your compiler didn't complain about that line, get another. ;-)

    Nonono, what I meant was there was a warning for that problem, but when I couldn't find anything wrong I stopped looking at that and tried stupid stuff with pointers. Like if you're looking for a book you lost, you're looking all over your house, but it turns out it was in the bookshelf all along.

    Compilers are not required to complain about such things anyway. In practice, some do and some do not.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Sunshine, and read this, this, and this before posting again.
