C Language Program for Beginners

Code :

#include <stdio.h>
int main()
{
    int i, j, k, l;
    for (i = 1; i <= 4; i++)
    {
        for (j = 5; j >= i; j--)
        {
            printf("*");
        }
        for (k = 2; k <= (i*2)-1; k++)
        {
            printf(" ");
        }
        for (l = 5; l >= i; l--)
        {
            printf("*");
        }
        printf("\n");
    }

    for (i = 5; i >= 1; i--)
    {
        for (j = 5; j >= i; j--)
        {
            printf("*");
        }
        for (k = 2; k <= (i*2)-1; k++)
        {
            printf(" ");
        }
        for (l = 5; l >= i; l--)
        {
            printf("*");
        }
        printf("\n");
    }
    return 0;
}

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.
First Outer Loop (Top Section): The first outer for loop (i = 1 to i <= 4) controls the rows of the top section, with stars decreasing and spaces increasing as the row number increases.
Inner Loop 1 (Stars on the Left for Top Section): The first inner for loop (j = 5 to j >= i) prints stars (*) on the left side, decreasing the number of stars as the row number increases.
Inner Loop 2 (Spaces for Top Section): The second inner for loop (k = 2 to k <= (i * 2) - 1) prints spaces to separate the two sets of stars, with the number of spaces increasing as the row number increases.
Inner Loop 3 (Stars on the Right for Top Section): The third inner for loop (l = 5 to l >= i) prints stars (*) on the right side, creating symmetry with the left side.
Second Outer Loop (Bottom Section): The second outer for loop (i = 5 to i >= 1) controls the rows of the bottom section, with stars increasing and spaces decreasing as the row number decreases.
Inner Loop 1 (Stars on the Left for Bottom Section): The first inner for loop (j = 5 to j >= i) prints stars (*) on the left side, increasing the number of stars as the row number decreases.
Inner Loop 2 (Spaces for Bottom Section): The second inner for loop (k = 2 to k <= (i * 2) - 1) prints spaces to separate the two sets of stars, with the number of spaces decreasing as the row number decreases.
Inner Loop 3 (Stars on the Right for Bottom Section): The third inner for loop (l = 5 to l >= i) prints stars (*) on the right side, creating symmetry with the left side.
New Line: printf("\n"); moves the output to a new line after printing each row.
