C++ code: Parallelogram star pattern program

In this article, we will discuss the C++ code: Parallelogram star pattern program

We can display many types of number, star, Alphabet, Binary patterns using for.while and do-while loop in C++ language

In this post, we are going to learn how to print Parallelogram star pattern using for, while and do-while loop in C++ language,

Note – Here,To create a this pattern, you can use either star or any symbol as you wish

Code to display Parallelogram star pattern using for loop

This program allows the user to enter the number of rows , columns and any character or symbols then the program displays the Parallelogram star pattern using for loop in C++ language

Program 1

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

int main() {
    int i,j,rows,columns;
    char ch;
    cout<<"Enter the number of rows\n";
cin>>rows;
 cout<<"Enter the number of columns\n";
cin>>columns;
cout<<"Enter the character for pattern\n";
cin>>ch;
cout<<"\n";

for(i=1; i<=rows; i++){//outer for loop
   for(j=1; j<=rows-i; j++){//inner for loop
   cout<<" ";//print space
   }
   for(j=1; j<=columns; j++){//inner for loop
   cout<<ch;//print symbol after space
}
 cout<<"\n";//move to next line
}
getch();
    return 0;
}

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

Code to display Parallelogram star pattern using while loop

This program allows the user to enter the number of rows , columns and any character or symbols then the program displays the Parallelogram star pattern using while loop in C++ language

Program 2

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

int main() {
    int i,j,rows,columns;
    char ch;
    cout<<"Enter the number of rows\n";
cin>>rows;
 cout<<"Enter the number of columns\n";
cin>>columns;
cout<<"Enter the character for pattern\n";
cin>>ch;
cout<<"\n";

i=1;
while(i<=rows){//outer while loop
        j=1;
   while(j<=rows-i){//inner while loop
   cout<<" ";//print space
 j++;
   }
   j=1;
   while(j<=columns){//inner while loop
   cout<<ch;//print symbol after space
    j++;
}
 cout<<"\n";//move to next line
 i++;
}
getch();
    return 0;
}

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

Code to display Parallelogram star pattern using do-while loop

This program allows the user to enter the number of rows , columns and any character or symbols then the program displays the Parallelogram star pattern using do-while loop in C++ language

Program 3

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

int main() {
    int i,j,rows,columns;
    char ch;
    cout<<"Enter the number of rows\n";
cin>>rows;
 cout<<"Enter the number of columns\n";
cin>>columns;
cout<<"Enter the character for pattern\n";
cin>>ch;
cout<<"\n";

i=1;
do{//outer do-while loop
        j=0;
 do{//inner do-while loop
   cout<<" ";//print space
 j++;
   }  while(j<=rows-i);
   j=1;
   do{//inner do-while loop
   cout<<ch;//print symbol after space
    j++;
}while(j<=columns);
 cout<<"\n";//move to next line
 i++;
}while(i<=rows);
getch();
    return 0;
}

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