Please write a simple and very basic C$++$program to answer this problem:

Problem#$4$: Pyramid Pattern

Write a C$++$ program that generates a Pyramid shape using nested loops and special

characters such as $*,$ #$,$ or @$.$ The program should allow the user to input a number n$,$ which

will determine the size of the pattern, and the special character $(^(**),$#$,$ or @$)$ that will be used

to draw the pattern.

Example $1$: Generate a pyramid shape with n rows using the # character $($n$=5).$

Example $2$: Generate a pyramid shape with n rows using the @ character $($n$=6).$
