C Program to Print Descending Number Pattern Using Loops

Descending Number Pattern in C

This C program prints a number pattern where each row contains numbers in ascending order, but the total number of elements decreases with each row. This is done using nested for loops.

✅ C Program Code:

#include <stdio.h>

int main()
{
    int num;
    printf("Enter the number:\n");
    scanf("%d", &num);
    for (int i = num; i >= 1; i--)
    {
        for (int j = 1; j <= i; j++)
        {
            printf("%d ", j);
        }
        printf("\n");
    }
}
  

💡 Explanation:

• User Input: The program asks for a number (e.g., 5).
• Outer Loop: Runs from the input number down to 1.
• Inner Loop: Prints numbers from 1 to the current value of i.

💻 Sample Output:

Enter the number:
5
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
