C++ program to create combined Pyramid pattern using while loop

In this tutorial, we will discuss a concept of the C++ program to create Combined Pyramid pattern

In the C++ programming language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star pattern programs.

In this article, we are going to learn how to Display combined Pyramid pattern using while loop in C++ language

Program to display combined Pyramid star pattern

Combined Pyramid star pattern 1

The C++ program allows the user to enter the number of rows then it displays two combined straight pyramid star pattern according to the number of rows.

Program 1

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

int main()
{
    int i,j,rows;
    cout<<"Enter the number of rows: \n";
    cin>>rows;
    cout<<"\n";

    i=1;
while(i<=rows){  //parent while loop
    j=i;
  while(j<=rows){
   cout<<" ";//print space
  j++;
  }
  j=1;
  while( j<=2*i-1){
   cout<<"*";//print star
   j++;
  }
  j=2*i;
   while(j<=2*rows-1){
   cout<<" ";//print space
  j++;
   }
   j=1;
  while( j<=2*i-1){
   cout<<"*";//print star
  j++;
  }
   cout<<"\n";//move to next line
i++;
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Combined Pyramid star pattern 2

The C++ program allows the user to enter the number of rows then it displays two combined upside-down pyramid star pattern according to the number of rows.

Program 2

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

int main()
{
    int i,j,rows;
    cout<<"Enter the number of rows: \n";
    cin>>rows;//Takes input from the user
    cout<<"\n";

    i=1;
while( i<=rows){//parent while loop
    j=1;
  while(j<i){
  cout<<" ";//print space
   j++;
  }
  j=1;
  while(j<2*(rows-i+1)){
  cout<<"*";//print star
   j++;
  }
  j=2;
   while(j<2*i){
  cout<<" ";
  j++;
   }
   j=1;
  while( j<2*(rows-i+1)){
  cout<<"*";//print star
   j++;
  }
  cout<<"\n";//move to next line
   i++;

}

getch();
    return 0;
}

When the above code is executed, it produces the following results

Program to display combined Pyramid number pattern

Combined Pyramid number pattern 1

The C++ program allows the user to enter the number of rows then it displays two combined straight pyramid number pattern according to the number of rows.

Program 1

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

int main()
{
    int i,j,rows;
    cout<<"Enter the number of rows: \n";
    cin>>rows;//Takes input from the user
    cout<<"\n";

    i=1;
while(i<=rows){  //parent while loop
    j=i;
  while(j<=rows){
   cout<<" ";//print space
  j++;
  }
  j=1;
  while( j<=2*i-1){
   cout<<j;//print number
  }
  j=2*i;
   while(j<=2*rows-1){
   cout<<" ";//print space
  j++;
   }
   j=1;
  while( j<=2*i-1){
   cout<<j;//print number
  j++;
  }
   cout<<"\n";//move to next line
i++;
}
