C++ Program to print right triangle star pattern

In this article, we will discuss the Program to C++ Program to print the right triangle star pattern

We can display many types of number, star, Alphabet patterns using for.while and do-while loops in c++

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

Code to print right triangle star pattern using for loop

This program allows the user to enter the number of rows then the program displays the right triangle star pattern using for loop in C++ language

Program 1

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

int main()
{
    int rows,i,j;
    cout<<"Enter the number of rows:\n";
    //input number of rows from user
    cin>>rows;
    //entered value store in the rows variable
    cout<<"\n";
for(i=1; i<=rows; i++){//outer for loop
   for(j=1; j<=i; j++){//inner for loop
   //print i number of star

       cout<<"*";//print ster

}

 cout<<"\n";//move to next line
}
getch();
    return 0;
}

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

Code to print right triangle star pattern using while loop

This program allows the user to enter the number of rows then the program displays the right triangle star pattern using while loop in C++ language

Program 2

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

int main()
{
    int rows,i,j;
    cout<<"Enter the number of rows:\n";
    //input number of rows from user
    cin>>rows;
    //entered value store in the rows variable
    cout<<"\n";
i=1;
while(i<=rows){//outer for loop
        j=1;
   while(j<=i){//inner for loop
   //print i number of star

       cout<<"*";//print ster
 j++;
}

 cout<<"\n";//move to next line
  i++;
}
getch();
    return 0;
}

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

Code to print right triangle star pattern using do-while loop

This program allows the user to enter the number of rows and the symbol then the program displays the right triangle star pattern using the do-while loop in C++ language

Program 3

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

int main()
{
    int rows,i,j;
    cout<<"Enter the number of rows:\n";
    //input number of rows from user
    cin>>rows;
    //entered value store in the rows variable
    cout<<"\n";
i=1;
do{//outer for loop
        j=1;
   do{//inner for loop
   //print i number of star

       cout<<"*";//print ster
 j++;
}while(j<=i);

 cout<<"\n";//move to next line
  i++;
}while(i<=rows);
getch();
    return 0;
}

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