The program to get output like this

4 4 4 4

//It's a simple program.Here we print only 9 rows.




#include<stdio.h>


#include<conio.h>


void main()

{

int i,n=9,k;



//Now we use this for loop to check the number of rows.


for(i=1;i<=n,i++)



//Here we use this for loop to print like 1 or 2 2 or 3 3 3.

     { for (k=1;k<=i;k++)

              printf("%d",i);
