I just got stuck with the pattern of zeroes , this shows that did you account for negative values

#1

#include
using namespace std;
int main() {
int N ;
cin>>N;
int num ;
cin>>num;
int i , j , k , l , m , n, o ;
for(int i = 1 ; i <= N ; i++)
{
if(num < 0)
{
if(i < N-2) //3
{
for(int j = 1 ; j <= i ; j++)
{
cout << num << “\t” ;

            }
            num++ ;
            cout << "\n" ;
        }
        else
        {
            for(int k = 1 ; k < 2 ; k++)
            {
                cout << num << "\t";
            }
            for(int l = 2 ; l < i ; l++)
            {
                cout << " 0" << "\t";
            }
            for(int m = 1 ; m < 2 ; m++)
            {
                cout << num << "\t" ;
                num++ ;
            }
            cout << "\n" ;
        }
    }
    else
    {
        if(i < N-2) //3
        {
            for(int j = 1 ; j <= i ; j++)
            {
                cout << num << "\t" ;
                
            }
            num++ ;
            cout << "\n" ;
        }
        else
        {
            for(int k = 1 ; k < 2 ; k++)
            {
                cout << num << "\t";
            }
            for(int l = 2 ; l < i ; l++)
            {
                cout << "0" << "\t";
            }
            for(int m = 1 ; m < 2 ; m++)
            {
                cout << num << "\t" ;
                num++ ;
            }
            cout << "\n" ;
        }
    }
}
return 0;
