Create A Number Pattern

I am trying to get this number pattern

Input: 7 
Output:  
1 1 1 1 1 1 1
1 2 2 2 2 2 1 
1 2 3 3 3 2 1 
1 2 3 4 3 2 1 
1 2 3 3 3 3 1 
1 2 2 2 2 2 1 
1 1 1 1 1 1 1 

But I can't figure out how to make it like that, any suggestion how to make that pattern??

My code so far :

int n, temp1, temp2,i,j;
cin >> n;
for (i = 1; i <= n; i++) {
    for (j = 1; j <= n; j++) {
        temp1 = j;
        temp2 = n-j+1;
        if (temp1 < temp2) cout << temp1;
        else cout << temp2;
    }
    cout << endl;
}

Thanks in advance.
