Array Question
 

I have an Array A[N]={1,2,3,4,5,6};
and I want to split it to 2 arrays of size N/2
such that B = 1, 2, 3 and C = 4, 5, 6
here is my program but there is something wrong with array C
Can you help me with it ?

#include <iostream.h>



void print(int X[], int newsize);

void main ()

{

        int const N=6;

        int A[N]={1,2,3,4,5,6};

        int C[N/2],B[N/2];



        for(int i =0;i<N;i++)

        {

                

                if(i>N/2)

                {

                        int k=0;

                        C[k]=A[i];

                k++;

                }

        else 

                B[i]=A[i];

        }

        print(B,N);

        cout<<endl;

        print(C,N);

}

void print(int X[],int size)

{

        int newsize;

        newsize=size/2;

        for(int i=0;i<newsize;i++)

                cout<<X[i]<<"\t";

}

Some general considerations first:

1 - main must return an int, so it's

int main()

and not

void main()

. I think your compiler should have issued a warning at least. Here's an explanation of why.
2 - you use deprecated

<iostream.h>

instead of

<iostream>

. To this also your compiler should have issued a warning. Take a look at this before changing it.

Coming to the "real" errors:
1 - instead of

if(i>N/2)

it should be

if(i>=N/2)

and
2 - You initialize k to 0 every time you enter the if block, basically rewriting only the first position of the C array. Take k declaration out of the loop, like this:

        int k=0;

        for(int i =0;i<N;i++) {

                if(i>=N/2) {

                        C[k]=A[i];

                        k++;

                }

                else 

                        B[i]=A[i];

        }

Thank you :D
it works now :)
