C Program to Print Consecutive Row Numbers in Right Triangle

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

#include <stdio.h>

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

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

    return 0;
}
C Program to Print Consecutive Row Numbers in Right Triangle

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

#include <stdio.h>

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

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

    return 0;
}
Enter Right Triangle Consecutive Row Nums Pattern Rows = 12

C Program to display consecutive row numbers in the right angled triangle using a do while loop.

#include <stdio.h>

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

    printf("\nThe Consecutive Numbers in Right Triangle Row Pattern\n"); 
    
	do 
	{
		val = i;
		j = 1 ;
		do	
		{
			printf("%d ", val);
			val = val + rows - j;

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

	} while(++i <= rows );

    return 0;
}
