Re: how to display this shape using for loop?
Here is a hint :
C++ Syntax (Toggle Plain Text)
  1. ********** 10 stars
  2. *********  9 stars
  3. ********   8 stars 
  4. *******   7 stars
  5. ******  6 stars
  6. ***** 5 stars
  7. **** 4 stars
  8. ***  3 stars
  9. ** 2 stars
  10. * 1 stars
  11. **  2 stars
  12. *** 3 stars
  13. **** 
  14. *****
  15. ******
  16. *******
  17. ********
  18. *********
  19. ********** 10 stars

So you see that they decrease by 1 star until they reach 1 then they
start increment.

so assuming you can separate this problem into 2 blocks, you can
do something like this :

C++ Syntax (Toggle Plain Text)
  1. for(int i = 10; i != 1; i--)
  2.      printStars(i); //a function that prints i stars with endl
  3. for(int i = 2; i <= 10; i++)
  4.      printStars(i);

Now what should your printStars look like :
for example if one calls printStars(4) it should output the following :
C++ Syntax (Toggle Plain Text)
  1. ****

Go ahead and try to devise printStars then you problem becomes much
easier.

re

This should do...

C++ Syntax (Toggle Plain Text)
  1. #include<iostream>
  2. using namespace std;
  3. void printstar(int num_of_times);
  4. void reverseprint(int highest);
  5. int main()
  6. {
  7.  for(int i=0;i<10;i++){
  8.  printstar(i);
  9.  }
  10.  reverseprint(10);
  11.  return 0;
  12. }
  13.  
  14.  void printstar(int num_of_times){
  15.  for(int i=0;i<num_of_times;i++){
  16.  cout<<"* ";
  17.  }
  18.  cout<<endl;
  19.  }
  20.  
  21.  void reverseprint(int highest){
  22.  for(int i=0;i<highest;i++){
  23.  int x=highest-i;
  24.  printstar(x);
  25.  }
  26.  cout<<endl;
  27.  }
Please, if this satisfies your problem,mark this thread as solved.Thanks
