array input

[invitro]

Ok, i have a little problem.
I have a 128 sized character array

chararray[128]

and im trying to have the user input stored in the array
cin >> chararray;

but it gives me an illegal operation when the user hits enter.

Now, i havent learned pointers yet but im traying to make a constant array that dosent resize, but only stores values.

This is a basic exercise im trying to work on just to see if it works. Can anyone help me out?

Thanks

Have you tried using cin.getline? That will make it slightly more flexible when using an array.

[invitro]

okay thanks i'm gonna go try that right now.

actually, i just tried it and i still get the illegal operation.

char fractarray[128]

cin.getline(fractarray, 128, '\n');

any other suggestions?

thanks

This works fine for me:

#include <iostream.h>

void main() {
	char fractarray[128];

	cin.getline(fractarray, 128, '\n');
	fractarray[127] = 0;
	cout << fractarray << endl;
}

The main change I made was to make sure that it is always null-terminated by setting the last character to 0.

Ok, this is stupid. I dont understand why its not working. It will give me a illigal operation but then it will cout the output. So I dont get it. I kind of feel stupid for not knowing how to do this since it seems so simple? ... I did exactly what you did, do you think there might be something wrong with my C version?

Im using VC++ 6 btw.

If you want I can post more code on there, but since its that chunk of code which isnt working, I thought it was the only problem... everything before and after works good if i take the cin out.

Any other suggestions?

Thanks for the help!

Bizarre

On VC++5 (no SP) it worked perfectly...I severely doubt it's a problem with VC++6, though. What code do you have that produces the illegal operation? Maybe something else has confused it somewhere.

Ok wierd, I went to another machine and I did the same code that you posted and it worked fine!!!
Now, I went back and I clicked on rebuild ALL and it executed fine.

So its fixed, I just dont know how?
O well, thanks for all the replies

[parksie]

Hmm Rebuild All does tend to fix things in many cases

Anyway, after a few more questions I would have had to have given up anyway...my brain's totally fried (5am here 'cause I'm still working on this $"&"&$ coursework!)
