Hello, I am a beginner at C++ and need some help with arrays..
- I need to create a function that returns a random number from a sequence of 4 #s.
- Then I have to loop it 1000x and print the frequency of those 4 #s.
So far I have:
and I understand I need to use:
rand(freq, n, ntimes);
and to output:
cout<<rndseq[i]<<" occured "<<freq[i]<<" times"<<endl;
Obviously, I havent had much time to work on it yet. I tried reading up on arrays but I did not find much on this specifically..
I just need someone to help me start off on the right foot. I'm not expecting anyone to fully write it for me. Just some pointers please. Much appreciated.

const int n=4, ntimes=1000;
int freq[n]={0};
short int seq[]={11,35,99,132};
and I understand I need to use:

and to output:
cout<<rndseq[i]<<" occured "<<freq[i]<<" times"<<endl;

Try organising your thoughts on paper first. If you know what flow charts are try drawing one.

[De-cloak] :eek:
Assuming that your array of random numbers is constant, then your 4 elements are always indexed by the numbers 0,1,2,3 .... that should make life pretty simple
Start it out as a simple random-number picker for the numbers 0-3 and carry on from there.
