C Exercises: Display the pattern like a pyramid with a number which will repeat the number in the same row

C For Loop: Exercise-17 with Solution

Write a program in C to make such a pattern like a pyramid with a number which will repeat the number in the same row.
The pattern is as follows:

   1
  2 2
 3 3 3
4 4 4 4

Sample Solution:

C Code:

#include <stdio.h>

void main()
{
   int i,j,spc,rows,k;
   printf("Input number of rows : ");
   scanf("%d",&rows);
   spc=rows+4-1;
   for(i=1;i<=rows;i++)
   {
         for(k=spc;k>=1;k--)
            {
              printf(" ");
            }
                      
	   for(j=1;j<=i;j++)
	   printf("%d ",i);
	printf("\n");
    spc--;
   }
}

Sample Output:

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