Matching Numbers in Arrays

This is a discussion on Matching Numbers in Arrays within the C++ Programming forums, part of the General Programming Boards category; Code: for(int j = 0; j <=5; j++) { if(Un[j]==Wn[j]) { counter++; cout << Un[j] << " "; } } ...

    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?

    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] << " ";
    		}
    }
