C Program to Print Consecutive Column Numbers in Right Triangle

Write a C program to print consecutive column numbers in right triangle pattern using the C Programming for loop.

#include <stdio.h>

int main()
{
    int i, j, rows, k = 1;
    
    printf("Enter Right Triangle Consecutive Col Nums Pattern Rows = ");
    scanf("%d",&rows);

    printf("Consecutive Numbers in Right Triangle Column Pattern\n"); 
    
	for (i = 1; i <= rows; i++ ) 
	{
		for (j = 1 ; j <= i; j++ ) 	
		{
			printf("%d ", k++);
		}
		printf("\n");
	}

    return 0;
}

This C example prints the right angled triangle pattern of consecutive column numbers using a C Programming while loop.

#include <stdio.h>

int main()
{
    int i = 1, j, rows, k = 1;
    
    printf("Enter Right Triangle Consecutive Col Nums Pattern Rows = ");
    scanf("%d",&rows);

    printf("Consecutive Numbers in Right Triangle Column Pattern\n"); 
    
	while (i <= rows ) 
	{
		j = 1 ;
		while( j <= i) 	
		{
			printf("%d ", k++);
			j++;
		}
		printf("\n");
		i++;
	}

    return 0;
}

Enter Right Triangle Consecutive Col Nums Pattern Rows = 12
