C program to print inverted pyramid number pattern

Ex: Write a C program to print inverted pyramid number pattern. How to write a C program to print inverted pyramid number pattern. C program to print inverted pyramid number pattern.

Input from user:

Enter the number: 5

Expected output:

      1  2  3  4  5

        1  2   3  4

          1   2  3

             1  2

               1

  Step by step logic of the given program:

1. Accept input(number) from user which shows number of rows, declare variable say no.

2. Run one outer  loop from 1 to no:

  for(i=1;i<=no;i++)

3. To print spaces run another for loop from 1 to i-1:

for(j=1;j<i;j++)

  printf(" ");

    

4. To print value of k use another one inner for loop from 1 to (no+1)-i:

for(k=1;k<=(no+1)-i;k++)

  {

  printf("%d ",k);

  }

    

5. For new row, move to next line using \n.

  Program to print inverted pyramid number pattern:

#include<stdio.h>

void main()

{

 int no,i,j,k;

 

 printf("Enter the no:\n");

 scanf("%d",&no);

 /*Run outer loop from 1 to no*/

 for(i=1;i<=no;i++)

 {   

   /*Run inner loop from 1 to i-1 to print spaces*/

  for(j=1;j<i;j++)

  {

  printf(" ");

  }

  /*Run another inner loop from 1 to (no+1)-i*/

  for(k=1;k<=(no+1)-i;k++)

  {

   /*print value of k with one space*/

  printf("%d ",k);

  }

  /*For next row*/

 printf("\n");

 }

}

Above program shows the following output:
