Pattern Question (stars pattern in descending order) with source code and small explanation 03 || Print pattern using c++ with 5 rows and 5 columns

Here I am going to print following pattern using c plus plus language in pattern question 

ALGORITHM FOR PRINTING STAR PATTERN IN DESCENDING ORDER :

1. header file include
2. use namespace which standard in c plus plus
3. Program's starting point : main() function
4. declared two variable a, b
5. get input of variable a,b
6. use for loop for row till a
7. use again for loop for column till b-(i-1) , here suppose b = 5 and i = 1 Now for first row where i=1 is running till 5-(1-1)=5 five. like this our loop work if i = 2 than loop will go through 5-(2-1)=4 four and so on.
8. print * stars using cout 
9. break line using line break endl after completing row.
10. return 0 to show that there is no error in the program.

YOU CAN COPY THIS CODE AS WELL !

#include <iostream>

using namespace std;

int main(){

    int a , b;

    cin>>a>>b;

    for (int i = 1; i <= a; i++)

    {

        for (int j = 1; j <= b-(i-1); j++)

        {

           cout<<"* ";

        }

        cout<<endl;

    }

     return 0;

}
