Matching Numbers in Arrays

Code:

---

for(int j = 0; j <=5; j++)
{
        if(Un[j]==Wn[j])
        {
                counter++;
                cout << Un[j] << " ";
        }
}

---

For some reason the code above doesn't work in my program :( Any solutions?

what happens? What are contained in all those vars? How bout postin it all (at least post the code with the declarations)

The beef:

Code:

---

int Un[6] = {0}, Wn[6] = {0};

Input:

cout << endl << "Please Enter Six Consecutive Numbers Ranging from 1-53:\n" << endl;
cin >> Un[0];

for(int k = 1; k <= 5; k++)
{
        int n = k - 1;        // Previous value

        if(Un[n] >= 1 && Un[0] <= 53)        // If it's valid
        {
                cin >> Un[k];        // Get next value
        }
        else
        {
                cout << "\a";
                goto Input;        // Else prompt again
        }
}

for(int i = 0; Wn[i] == 0; i++)        // Fill Wn[] with random values
{
        Wn[i] = rand()%53;
}

cout << endl << endl << "Matching Numbers: ";

int counter = 0;        // Keep track of matching numbers

for(int j = 0; j <=5; j++)
{
        if(Un[j]==Wn[j])
        {
                counter++;
                cout << Un[j] << " "; // This doesn't show
        }
}

cout << endl << endl

if(counter==0)        // These don't show either
{
        //.....
}
else if(counter==1)
{
        //.....
}
else if etc etc...

Code:

---

#include <iostream>
#include <cstdlib>
#include <ctime>


int main(){

        using namespace std;
       
        srand(time(NULL));//first randomise
       
        const int nArraySize = 6;
        int Un[nArraySize] = {0},
                Wn[nArraySize] = {0};
               
        cout << endl << "Please Enter Six Consecutive Numbers Ranging from 1-53:\n" << endl;
       
        for(int i = 0;i < nArraySize;++i){
                cin >> Un[i];
                if(Un[i] > 53){//if over 53
                        cout << "Not under 54!" << endl;
                        --i;//lower count
                }
        }
       
       
        for(int i = 0;i < nArraySize;++i)
                Wn[i] = rand()%54;//between 0 and 53
               
        cout << endl << endl << "Random Numbers: ";
       
        for(int i = 0;i < nArraySize;++i)
                cout << Wn[i] << " ";
               
        cout << endl << endl << "Matching Numbers: ";

        int counter = 0;// Keep track of matching numbers
       
        for(int i = 0;i < nArraySize;++i)
                for(int j = 0;j < nArraySize;++j)//nested loop
                        if(Un[i]==Wn[j]){
                                counter++;
                                cout << Un[i] << " ";
                }
}

Thanks, it all works now!
