Output: (If user puts 5 as input)

Enter the height of Pyramid:  5

9. Pascal’s Triangle Pyramid of Numbers

Code:

#include <iostream>
using namespace std;


int main()
{
//considering variables
    int h, pt = 1;


//asks user for a input
    cout << "Enter number of rows: ";


//storing value in variable h
    cin >> h;


//logic
    for(int m = 0; m < h; m++)
    {
        for(int sp = 1; sp <= h-m; sp++)
            cout <<"  ";


        for(int n = 0; n <= m; n++)
        {
            if (n == 0 || m == 0)
                pt = 1;
            else
                pt = pt * (m-n+1)/n;


            cout << pt << "   ";
        }
        cout << endl;
    }


    return 0;
}

Output: (If the user puts 6 as input)

Enter number of rows: 6
            1
          1   1
        1   2   1
      1   3   3   1
    1   4   6   4   1
  1   5   10   10   5   1

10. Half Pyramid Pattern of Alphabets

Code:

//cpp to print half pyramid pattern of alphabets


#include <iostream>
using namespace std;


int main()
{
//considering variables
    char ip, alph = 'A';


//asks user for a input
    cout << "Enter any uppercase character to print in the end row: ";
   //storing input
 cin >> ip;


//logic
    for(int m = 1; m <= (ip-'A'+1); ++m)
    {
        for(int n = 1; n <= m; ++n)
        {
            cout << alph << " ";
        }
        ++alph;


        cout << endl;
    }
    return 0;
}

Output: (If user puts “F” as input)

Enter any uppercase character to print in the end row: F
A
B B
C C C
D D D D
E E E E E
F F F F F F

11. Full Pyramid Pattern of Alphabets

Code:

//cpp to print full pyramid pattern of alphabets


#include <iostream>  
using namespace std; 
 
int main()  
{  
//taking variable
 char alpha= 'A';    
    int sp, m, n, o, p;   


//asks user for input
     cout << "Enter the height of Pyramid: ";


//storing value
	 cin >> sp;
	 
//logic
    for( m = 1; m <= sp; m++ )    
    {    
        for( n = sp; n >= m; n-- )    
            cout<<" ";    
        for(o = 1; o <= m; o++)    
            cout << alpha++;    
            alpha--;    
        for( p = 1; p < m; p++)    
            cout<<--alpha;    
        cout<<"\n";    
        alpha='A';    
    }    
return 0;  
}  

Output: (If user puts 5 as input)

Enter the height of Pyramid: 5
     A
    ABA
   ABCBA
  ABCDCBA
 ABCDEDCBA
