int main()
{
int i, j, k, num;
printf("\nEnter a number: ");
scanf("%d",&num);
printf("\n");
for(i = 0; i < num; i++)
{
for(k = 0; k < i+1; k++)
{
printf(" ");
}
for(j = 0; j < num; j++)
{
if(i == 0 || i == num - 1)
{
printf("*");
continue;
}
if(j == 0 || j == num - 1)
printf("*");
else
printf(" ");
}
printf("\n");
}
return 0;
