Array question HELP!!

I need to write a program that accepts an integer n, where n is the number of elements going into the array. Have the user input n, integers. Have a function that ouputs the current array. And have another function that bubblesorts the array. Then have the output function, output the sorted array.

I have written this code thus far, however. When compiled and run, it will ask for n, but there will be a blank line as if asking for something else, then it will run the loop, but for the %d integers in the print line, it'll have some bogus number "2293212" and then only accept 3 inputs and then crash.

Any help would be greatly appreciated, thanks.

scanf wants pointers. So you need to pass it the address of [b]n[/n], not the value of [b]n[/n]. (The value of n is unspecified, because you didn't initialize it.

Code:

---

scanf( "%d", &n );

Quzah.

caught that error before you responded, still does the exact same thing. Gives a bogus number and takes 3 inputs and then closes.

so I fixed the bogus number problem by removing the & before the n in the print statement.

But it still has an extra place for the user to input something after getting "n" before the loop starts and it's still always only accepting 3 inputs and then crashing.

I suggest that you compile with warnings turned on to a suitable high level (e.g., at least the -Wall option for gcc and at least the /W3 option for MSVC). This should result in a warning that reveals that you did not finish doing what quzah suggested.

Very wise words indeed. I don't know how to make it stricter because im using bloodshed DEV C++ compiler, but seeing that you said I didn't do everything quzah suggested, I added an & before the a[k];. Now it accepts the correct number of integers.

Now theres a new problem, after it executes the first function, it pauses, and doesn't do anything. Program doesn't continue. I have added the function to the code.

Ok, the whole program seemingly executes now, however sometimes it freezes after the first function and doesn't go anywhere, and also there is something wrong with my bubble sorting function. It does not sort every number from lowest to highest like it's supposed to. This is the function.

nevermind fixed everything myself, thanks all
