Number Magic2 Using For loop #c

The Output look like this

1
2 3
4 5 6
7 8 9 10

//Lets start the program



#include<stdio.h>



#include<conio.h>



void main()

{

int j,k,b=31,c;



clrscr();



for(c=9;c>=1;c=c-1,b=b+1)



   {printf("\n");



    for(j=1;j<=b;j++)



    printf(" ");



    for(k=1;k<=c;k++)



    printf("%d ",c);



    }

    getch();

    }

Lets Start Next Program. The Out Will look like this.
                                                   1
                                                 2  3
                                               4  5  6
                                             7  8  9  10
