Here is the C++ code to output like above . You all should have in mind how it works exactly. Here is the algorithm.

  Steps

User side

1: When user run this code it simply output the result 

Developer side

1: Declare variables that are going to be used in program .

2: Start a loop from i=1 to 10 (increase it by 2 after each iteration)

3:  Inside the above loop initialize a variable equal 1 and iterate it until the following statement fails n<=i

4:output the "*" (this will output above triangle )

5: start a loop from i=10 to 1 (decrease it by 2)

6: Inside above loop start a loop from 1 to less than i 

7 : Inside above loop output "*"

8: Program ends here 

Code:

//start

#include<iostream>

using namespace std;

void main()

{      //first triangle

       for(int i=1;i<=10;i=i+2)

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

                     {

                           cout<<"*";

                     }

                     cout<<endl;

              }

       //2nd triangle

              for(int i=10;i>=1;i=i-2)

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

                     {

                           cout<<"*";

                     }

                     cout<<endl;

              }

             

       system("pause");

}

//End

Output:
