Thread: 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] << " ";
		}
}

Thanks, it all works now!
