Header File: #include <stdio.h> is
needed to use printf() for printing output.
Main Function: The program starts from
int main(). It returns 0 to indicate successful completion.
Outer Loop (Rows): The outer for loop (i = 1 to 5) controls the number of rows. In each row, numbers will be printed in descending order, starting from 5.
Inner Loop (Columns): The inner for loop
(j = 5 to j >= i) prints numbers starting from 5 down to the
current row number i.
New Line: printf("\n"); moves the output to
a new line after printing each row.
