Cpp program to display Pyramid star pattern

Cpp program to display Pyramid star pattern

In this tutorial, we will discuss about Cpp program to display Pyramid star pattern

In this topic, we will learn how to create Pyramid star pyramid pattern in C++ language using nested for loop

 

Star Pyramid pattern 1

Program 1

Pyramid pattern

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows;
    cout << "Enter the number of rows" << endl;
    cin>>rows;
    for(int i=1; i<=rows;  i++){//outer for loop
            for(int j=1; j<=(rows-i)*2; j++){
                cout<<" ";//print space fot pyramid
            }
            for(int k=i; k>=1; k--){//inner for loop
                cout<<" "<<"*";  //create left half
            }
            for(int l=2; l<=i; l++){
                 cout<<" "<<"*" ; //create right half
            }
 cout<<"\n";
    }
     getch();
    return 0;
}

 

Enter the number of rows
6      
            *
          ***
        *****
      *******
    *********
  ***********

 

Star Pyramid pattern 2

Program 2

Inverted Pyramid pattern

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows;
    cout << "Enter the number of rows" << endl;
    cin>>rows;
    for(int i=rows; i>=1;  i--){//outer for loop
            for(int j=i; j<=rows; j++){
                cout<<" ";//print space fot pyramid
            }
            for(int j=1; j<=(2*i-1); j++){//inner for loop
                cout<<"*";  //print star
            }
 cout<<"\n";//move to next line
    }
     getch();
    return 0;
}

 

Enter the number of rows
6

Star Pyramid pattern 3

Program 3

Right leaned Pyramid pattern

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows;
    cout << "Enter the number of rows" << endl;
    cin>>rows;
    for(int i=1; i<=rows;  i++){//outer for loop
            for(int j=1; j<=i; j++){//inner for loop 
                cout<<"*";//print star fot pyramid top half
            }
             cout<<"\n";  //move to next line
    }
            for(int i=rows; i>=1; i--){//outer for loop
            for(int j=1; j<=i; j++){//inner loop
                 cout<<"*" ; //print star for bottom half
            }
 cout<<"\n";
    }
     getch();
    return 0;
}

 

Enter the number of rows
6

Star Pyramid pattern 4

Program 4

Left leaned Pyramid pattern

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows;
    cout << "Enter the number of rows" << endl;
    cin>>rows;
    for(int i=1; i<=rows;  i++){//outer for loop
            for(int j=i; j<rows; j++){
                cout<<" ";//print space for pyramid
            }
            for(int j=1; j<=i; j++){
                    cout<<"*";//print star for pyramid top part
                    }//inner for loop
                     cout<<"\n";
    }

            for(int i=rows; i>=1;  i--){//outer for loop
            for(int j=i; j<=rows; j++){
                cout<<" ";//print space for pyramid
            }
            for(int j=1; j<i; j++){
                    cout<<"*";//print star for pyramid below part
                    }//inner for loop
                     cout<<"\n";
    }
     getch();
    return 0;
}

 

 

  Enter the number of rows 
6      
         *
