C Program to Print K Shape Number Pattern

Write a C program to print K shape number pattern using for loop.

#include <stdio.h>

int main()
{
    int i, j, rows;
    
    printf("Enter K Shape Numbers Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Numbers Pattern\n"); 
    
    for (i = rows; i >= 1; i-- ) 
	{
		for (j = 1 ; j <= i; j++ ) 	
		{
			printf("%d ", j);
		}
		printf("\n");
	}
		
	for (i = 2 ; i <= rows; i++ ) 
	{
		for (j = 1; j <= i; j++ ) 	
		{
			printf("%d ", j);
		}
		printf("\n");
	}
    return 0;
}

This C example prints the K shape pattern of numbers or integers using a while loop.

#include <stdio.h>

int main()
{
    int i, j, rows;
    
    printf("Enter K Shape Numbers Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Numbers Pattern\n"); 
    i = rows;

    while( i >= 1 ) 
	{
		j = 1 ;
		while( j <= i ) 	
		{
			printf("%d ", j);
			j++;
		}
		printf("\n");
		i--;
	}

	i = 2 ;
	while ( i <= rows ) 
	{
		j = 1;
		while ( j <= i) 	
		{
			printf("%d ", j);
			j++;
		}
		printf("\n");
		i++;
	}
    return 0;
}

Enter K Shape Numbers Pattern Rows = 11

C Program to display a K shape numbers pattern using a do while loop.

#include <stdio.h>

int main()
{
    int i, j, rows;
    
    printf("Enter K Shape Numbers Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Numbers Pattern\n"); 
    i = rows;

    do
	{
		j = 1 ;
		do 	
		{
			printf("%d ", j);

		} while( ++j <= i );
		printf("\n");

	} while( --i >= 1 );

	i = 2 ;
	do 
	{
		j = 1;
		do 	
		{
			printf("%d ", j);

		} while ( ++j <= i);
		printf("\n");

	} while ( ++i <= rows );
    return 0;
}
