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 i <= 5) controls the number of rows, decreasing the number of stars printed on each successive row.
Inner Loop 1 (Spaces): The first inner for loop (j = 1 to j <= i) prints spaces to shift the stars to the right, creating an inverted pyramid structure.
Inner Loop 2 (Stars): The second inner for loop (k = 5 to k >= i) prints a star (*) followed by a space, with the number of stars decreasing as the row number increases.
New Line: printf("\n"); moves the output to
a new line after printing each row.
