Program in C to print different types of structure

For printing this type structure in C:

* * * * * 

* * * * * 

* * * * * 

* * * * * 

* * * * * 

Here as we seen the figure is in row and column form thus we have to declare two variable ( i and j ) for row and column respectively. Here we use for loop statement of c.

/* program to print structure */

#include<stdio.h>

void main()

{

int i,j,n ;

clrscr () ;

printf ("\n Enter number of rows:") ;

scanf ("%d", &n) ;

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

{

for (j=1;j<=n;j++)

{

printf ("*") ;

printf ("  ") ;

}

printf ("\n") ;

}

getch () ;

}

Output screen :: 

Enter number of rows :: 5

output ::

printf ("*") ;

printf ("  ") ;

}

printf ("\n") ;

}

getch () ;

}

Both of program have nearly same syntax but there is small change in their column for loop statement in case of first type their condition is for (j=1;j<=n;j++) and in case second we have use for (j=1;j<=i;j++).

Output Screen :: 

Enter number of rows :: 5
