In this program i enter the names of 40 friends.

I need to display the names 15 at a time, pausing before continuing with the list.
Still haven't figured out a way to do it.

So far this is what i could come up with:

Well, right now it is pausing after the first 15 but not after 30 it looks like. I think if you change your "if" statement to this:






it will execute the get character pause every 15 names.

Do you also know why when i input for example:
JENIFER it only outputs the first letter. 'J'

You've set up an array of characters and you are using "get", which I believe only gets one character. I think you want an array of strings or c-strings rather than an array of characters. Try this:




I'm pretty sure "get" only gets a character at a time. "getline" will get an entire line and you may consider that if you want first and last names. Otherwise, plain old "cin" works. Regardless, as you had it, you were only allocating space for forty characters total before and you need more for forty names.

I'm not sure why you were using "ignore". I don't think you need the
system ("CLS") command in there either, at least not inside the for-loop. I'm not too familiar with it or "ignore" so there may be a reason.

cin.ignore () is used to consume all potential additional letters of a name.

EDITED:::

I need to use C-Style strings... not C++ Style strings..

The only errors associated with that code have nothing to do with the actual use of the string - the errors are related to the lack of the inclusion of the proper <string> header, some scoping issues, and the lack of a proper namespace.

The problem with your original code is that you aren't using an array of C-strings, you're using an array of characters. To get an array of C-strings (null-terminated character arrays), you'd need to use a 2-dimensional array of characters:


This will require changing some additional parts of your code. Is this more like what you're trying to do?

Just ran the code. Ran fine when I added "using namespace std" and took out the other namespace stuff. I think I needed "std::string" or something instead of "string" without using "namespace std". I did notice that it prints 16 names instead of 15 at first. To fix, you can either put the if statement before the printing or subtract 1 from i in the if statement. C-string or string, whichever you prefer. jjhaag is correct that you need a 2-D array since a C-string is a one dimensional array of characters and you need an array of C-strings, which makes it two dimensional.

You can change the last line back to your line: _getch();


My i variable was out of scope, as jjhaag pointed out. Hadn't meant to put that line there.

Probably. Could you give me a simple example. for example the input ?

Even if i use the script i still need to use a variable for the number of names and a variable for the max characters per name. I just cant think of a way to do it but using a double for but that will make it two inputs..

I'm not sure what you mean by that. Yes, you need a (const) variable for each of those terms. But why on earth would you need a double? Both the number of friends and the lengths of their names are integers. When using C-strings, you generally don't use the exact length of the the inputted string as the length of the character array that you are storing into - you use a buffer that is longer than the maximum expected length of the string.

This was from a previous post in this thread:

This creates an array 40 elements long, where each element is ANOTHER array, 20 characters long. The first index into the array gives you the friend number. And the syntax for the get() method is given by:


So to store the name of the 5th friend, you would use:

This tells the cin object to pull in a maximum of maxNameLength characters into the 5th row (zero-based arrays in C/C++, remember) of the array. The '\n' delimiter tells it to stop reading when a newline character is found in the input buffer.

If you expect that the names are going to be longer than 20 characters, change that const int variable to something bigger - most first or last names are shorter than 20 characters, but if you feel you need to go with a bigger buffer, go for it.

Anyways thank you both for the help...
Cheers..
