How to print the letters backwards

[muuucow]

I need to print this pattern:
JIHGFEDCBA
IHGFEDCBA
HGFEDCBA
GFEDCBA
FEDCBA
EDCBA
DCBA
CBA
BA
A

The bottom is what I have written so far. What am I doing wrong or what else do I have to add?

#include <iostream>
using namespace std;

int main()
{
    int n = 10; 
    
    for (int i = 1; i <= n ; i++) 
        {
        char letter = 'A';
        for (int j = 1; j <= (n+1) - i ; j++) 
                {
                 
                 cout << letter;
                 letter++;                 
                 
        
        
        }
        cout << endl;        
                   
    }
    cout << endl;


    system ("PAUSE");
    return 0;
    
}  

The code I have written prints out:
ABCDEFGHIJ
ABCDEFGHI
ABCDEFGH
ABCDEFG
ABCDEF
ABCDE
ABCD
ABC
AB
A

Your current inner loop starts with lowest index and then steps ++j towards the highest. Start from highest and step --j towards the lowest.

[Edit] Oh, your loop index j is a bogus, so changing it does not directly help. You do math with char. Do some more. Start from 'J' rather than 'A'.
