pattern1 : Print the stars

#include<conio.h>
#include<stdio.h>
void main()
{
int i,j,n;
clrscr();
printf("\nEneter the no of lines to be printed: ");

scanf("%d",&n);
for(i=0;i<n;i++)
{
for(j=0;j<=i;j++)
{
printf("*");
}
printf("\n");
}
getch();
}

Star pattern 2

#include<conio.h>
#include<stdio.h>
void main()
{
int i,j,n;
clrscr();

printf("\nEneter the no of lines to be printed: ");
scanf("%d",&n);
for(i=0;i<n;i++)
{
for(j=n-i;j>1;j--)
{
printf(" ");
}
for(j=0;j<=i;j++)
{
printf("*");
}
printf("\n");
}
getch();
}

Star pattern 3

scanf("%d",&n);
for(i=0;i<n;i++)
{
for(j=0;j<n-i;j++)
{
printf("*");
}
for(k=0;k<(2*n-2*j);k++)
{
printf(" "); //for spaces
}
for(j=0;j<n-i;j++)
{
printf("*");
}
printf("\n");
}
getch();
}

   if(i!=0)
   printf("*");
   printf("\n");

{
printf("*"); // star
}
printf("\n");
}
}
pattern 8:program for simple star pyramid in reverse order

star pyramid reverse

//clrscr();
printf("Enter the number of lines to be ptinted");
scanf("%d",&n);
for(i=0;i<n;i++)
{
for(j=0;j<i;j++)
{
printf(" ");
}
for(k=2*(n-i)+1;k>1 ;k--)
{
printf("*");
}
printf("\n");
}
}

The program below is good program can be asked for coding compititions
