 * C program to print number pattern
 */

#include <stdio.h>

int main()
{
    int i, j, N;

    printf("Enter N: ");
    scanf("%d", &N);

    for(i=N; i>=1; i--)

        for(j=1; j<i; j++)
        {
            printf(" ");
        }

        // Logic to print numbers

📘 Explanation

Logic to print the given number pattern

If you look to the above pattern you will find that it is same as the pattern we just printed above except of trailing spaces. Hence, the whole logic of printing the pattern will be same as first pattern, we only need to add the logic to print spaces. If you hover mouse on to the pattern you can see or count total spaces per row. In the given pattern each row contains i - 1 spaces (where i is the current row number). Note that row are in descending order i.e. row1 is 5, row2 is 4 and so on.
Step-by-step descriptive logic:

To print spaces, run an inner loop from 1 to i. Inside this loop print single blank space.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
