write a c++ program to produce following design

Question

ZYXWVWXYZ
ZYXWXYZ
ZYXYZ
ZYZ
Z

Answer 1

Your char array is initially
[Z, Y, X, W, V]
You can use 2 for loops to iterate the array left to right and right to left (not including the last char) inorder to write
ZYXWVWXYZ
Then shift the first 4 chars one position to the right and replace the first with a space.
REPEAT UNTIL YOU HAVE ONLY WHITE SPACES IN YOUR CHAR ARRAY

Answer 2

This pattern is known as palindrome triangle pattern where every row is a palindrome string of odd numbers of characters. In Nth row the number of characters will be 2N+1.
Here s a similar C program to print palindrome triangle pattern
