In this tutorial, we will discuss a simple concept of the Program to Double pyramid star pattern in C++
In this post, we will learn how to create double (integrated) pyramid star pattern in C++ language.
We can use for loop, while loop or do while loop to display different integrated star patterns.
Here, we will use for loop to print different integrated pyramid star patterns
Program 1
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j; cout << "Enter the number of rows: "<< endl; cin>>rows;//take input from user for rows for(i=1; i<=rows; i++){ //print upper part for(j=i; j<=rows; j++){ cout <<"*";//print star to upper part } cout << "\n"; } for(i=rows-1; i>=1; i--){ //print lower part for(j=i; j<=rows; j++){ cout << "*";//print star to lower part } cout << "\n"; } getch(); return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 6 ****** ***** **** *** ** * ** *** **** ***** ******
Program 2
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j,k; cout<<"Enter the number of rows\n"; cin>>rows;//take input from user for rows for(i=1; i<=rows; i++){ //print upper part for(j=1; j<=i; j++){ cout<<" "; } for(k=i; k<=rows; k++){ cout<<"*";//print star to upper part cout<<" "; } cout<<"\n";//move to next line } for(i=rows-1; i>=1; i--){ //print lower part for(j=1; j<=i; j++){ cout<<" "; } for(k=i; k<=rows; k++){ cout<<"*";//print star to lower part cout<<" "; } cout<<"\n"; } getch(); return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 6 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
Program 3
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j; cout<<"Enter the number of rows: "; cin>>rows;//take input from user to rows for(i=1; i<=rows; i++){ //print upper part for(j=1; j<i; j++){ cout<<" ";//print space } for(j=i; j<=rows; j++){ cout<<"*"; } cout<<"\n"; } for(i=rows-1; i>=1; i--){ for(j=1; j<i; j++){ cout<<" ";//print space } for(j=i; j<=rows; j++){ //print lower part cout<<"*"; } cout<<"\n"; } return 0; }
When the above code is executed, it produces the following result
Enter the number ofrows: 6 ****** ***** **** *** ** * ** *** **** ***** ******
Program 4
#include <iostream> #include <conio.h> using namespace std; int main() { int rows,i,j,k; cout<<"Enter the number of rows: "; cin>>rows;//take input from user for rows for(i=1; i<=rows; i++){ //print upper part for(j=1; j<=rows-i; j++){ cout<<" "; } for(k=1; k<=i; k++){ cout<<"*";//print star to upper part cout<<" "; } cout<<"\n"; } for(i=1; i<=rows-1; i++){ //print lower part for(j=1; j<=i; j++){ cout<<" "; } for(k=1; k<=rows-i; k++){ cout<<"*";//print star to lower part cout<<" "; } cout<<"\n"; } getch(); return 0; }
When the above code is executed, it produces the following result
Enter the number of rows: 6 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
