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

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:

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

Input from user:

Enter the number: 5

Expected output:

1 2

1 2 3

1 2 3 4

1 2 3 4 5

Step by step logic of the given program:

This pattern is same as previous exercises star pyramid pattern:

***

****

*****

Difference is:

In this pattern we only need to replace the * with value of k .

1. Accept input number from user.

2. Run outer for loop from 1 to no which shows rows in pattern:

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

3. Run inner for loop from i to no-1 to print spaces:

for(j=i;j<no;j++)

{

printf(" ");

}

4. Run another inner for loop from 1 to i which shows columns in pattern:

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

5. Inside the second inner for loop print value of k with one space:

printf("%d ",k);

6. After that outside the block of inner for loop print next line \n for print new row.

Program to print number pyramid pattern :


#include<stdio.h>
void main()

{

	int no,i,j,k;

	printf("Enter the number:");

	scanf("%d",&no);

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

	{

		for(j=i;j<no;j++)

		{

		/*Print spaces*/

		printf(" ");

      		}

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

		{

		/*print value of k with one space...to print it like a pyramid*/

		printf("%d ",k);

		}

		/*For next row*/
        	printf("\n");

	}


}

Above program shows the following output:
