C Exercises: Display the pattern like right angle triangle with number increased by 1

C For Loop: Exercise-12 with Solution

Write a program in C to make such a pattern like right angle triangle with number increased by 1.
The pattern is as follows :

   1
   2 3
   4 5 6
   7 8 9 10

Sample Solution:

C Code:

#include <stdio.h>
void main()
{
   int i,j,rows,k=1;
   printf("Input number of rows : ");
   scanf("%d",&rows);
   for(i=1;i<=rows;i++)
   {
	for(j=1;j<=i;j++)
	   printf("%d ",k++);
	printf("\n");
   }
}

Sample Output:

Input number of rows : 4                                                                                      
1                                                                                                             
2 3                                                                                                           
4 5 6
