Your question is a bit unclear. Are you asking for something like:

int nNumbers[] = {5, 8, 7, 1, 5, 0, 2, 8};
cin >> nIndex;
cout << nNumbers[nIndex];

I want the user to input say cin>>array[i] user puts in 16 and it searches for array field 16 if it is a 1 then i want it to display hit otherwise if it is zero then miss. but i think i could us an if...else...statment?

Yes, you'll need an IF. You want to do different things depending on a condition. That's what if does.

This is very basic stuff - can I point you to a good book? I learnt a lot from:
http://www.amazon.co.uk/C-Programming-Language-2nd/dp/0131103628/ref=sr_1_12?ie=UTF8&s=books&qid=1237899112&sr=8-12[^]

It's pure C, and won't cover cin / cout, but you need to get the fundamentals of if / while / for under your belt before you can do anything with C/C++/any programming language. It's also quite a small book, but loads of information on every page.

Good luck with your journey,

In my project, I got the following error:

fatal error C1083: Cannot open include file: 'xercesc/util/XercesDefs.hpp': No such file or directory

But this was there in the following path:

D:\Development\GlestOld\xerces-c_2_8_0-x86-windows-vc_8_0\include\xercesc\util

I've added this path to the Additional Include Directories in the project Settings.

I've also added the following library path to Additional Library Directories in the project settings.

D:\Development\GlestOld\xerces-c_2_8_0-x86-windows-vc_8_0\lib

But the errors persists. What to do?

Regards,

If you added this exact path: "D:\Development\GlestOld\xerces-c_2_8_0-x86-windows-vc_8_0\include\xercesc\util" to the include directory, then you need to include "XercesDefs.hpp" and not "xercesc/util/XercesDefs.hpp".

Hi people,

I dont know if anyone can help really, I have got to set up an array of size 20 easy Smile | :)

but what i need to do and not sure how to is to randomly assign 6 positions in the array with a 1. Any ideas?

Mahesh Kulkarni24-Mar-09 1:24

if u want to fill six positions out of 20 you can use
Array[rand()%20] = somevalue..

are you looking for this functionality?

thank you very much do u do thi whilst you are declaring it? or in the main part of code?

Eytukan24-Mar-09 1:27

24-Mar-09 1:27

You need to generate

int arr[20]={0};
for(int i=0;i<6;i++)
{
    int i = 0 + rand() % (19 - 0);
    arr[i]=1;
    printf("\n%d",i);
}
for(int i=0;i<19;i++)
{
    printf("\n%d",arr[i]);
}

You might also add a condition to check for repetitions in the random generated nos.
