hollow diamond using for loop c++ code user enter input size of diamond

, , , , , , , 9 comments
write a c++ program which takes size of diamond and display hollow diamond using nested for loop and asterisk character.
Output should be look like bellow
hollow diamond using for loop c++ code user enter input size of diamond



 User can enter its desired size of diamond either even or odd

For Example
If user enters size of 3
3 lines of will be formed above middle and 3 lines will be formed below middle line
sample output for program hollow diamond using for loop c++ code user enter input size of diamond
Concept used:
c++ code:


#include<iostream>
using namespace std;
int main()
{
cout<<"Enter size of  Daimond:  ";

    int size;
  cin>>size;

    int z=1;
  for ( int i=0; i<=size; i++)
  {
    for (int j=size; j>i; j--)
    {
      cout<<" "; // printing space here
    }

    cout<<"*";  // printing asterisk here

    if ( i>0)
    {
      for ( int k=1; k<=z; k++)
      {
        cout<<" ";
      }
      z+=2;
      cout<<"*";
    }
    cout<<endl; // end line similar  to \n
  }

  z-=4;

  for (int i=0; i<=size-1; i++)
  {
    for (int j=0; j<=i; j++)
    {
      cout<<" ";
    }

    cout<<"*";

    for (int k=1; k<=z; k++)
    {
      cout<<" ";
    }
    z-=2;

    if (i!=size-1)
    {
      cout<<"*";
    }
    cout<<endl;
  }
return 0;
}


If user enter size equal to 10
hollow diamond using for loop c++ code user enter input size of diamond size equal 10

Recommended: Dry run the code line by line it will help to understand quickly and also clear the working of nested for loop.

write a c++ program which displays an inverted triangle using nested for loop and asterisk character

Use any Compiler IDE you want.
Required Output should be look like below image.

Compiler used: CodeBlocks c++ Compiler
c++ code:



#include<iostream>
using namespace std;
int main()
{

     cout<<"\"Inverted Triangle Shape\"\n\n";


  int w=6;

   for(int g=0;g<9;g++)
 {
  cout<<"*";    // Displaying asterisk here
 }
  cout<<endl; // endl is for new line

  for(int a=1;a<=3;a++)
 {

    for(int b=0;b<a;b++)
   {
    cout<<" ";    // displaying space here
   }
    cout<<"*";


      for(int c=1;c<w;c++)
     {
      cout<<" ";
     }
      cout<<"*"<<endl;
      w=w-2;
 }

  for(int e=1;e<=1;e++)
 {

    for(int f=4;f>=e;f--)
   {
    cout<<" ";
   }
    cout<<"*";
 }

  return 0;
}

These kinds of programs are basic level program can be coded in more than one way it is recommended to change the logic of program and do experiment with the code for better understanding
