The given number pattern is similar to the previous number pattern. Also logic of this pattern would be very much similar to the previous pattern.

Must know –

Logic to print the given pattern is.

  1. Print the value of num (where num is the number entered by user).
  2. Remove the first digit of the number, as it isn’t needed anymore.
  3. Repeat steps 1-3 till the number is greater than 0.

Program to print the given number pattern

/**
 * C program to print the given number pattern
 */

#include <stdio.h>
#include <math.h>

int main()
{
    int num, firstDigit, digits, placeValue;

    printf("Enter any number: ");
    scanf("%d", &num);

    while(num > 0)
    {
        printf("%d\n", num);

        digits = (int) log10(num);                // Get total number of digits
        placeValue = (int) ceil(pow(10, digits)); // Get the place value of first digit
        firstDigit = (int)(num / placeValue);     // Get the first digit

        num = num - (placeValue * firstDigit);    // Remove first digit from number
    }

    return 0;
}

Output

Enter any number: 24165
24165
4165
165
65

Happy coding 😉
