triangle number pattern Using nested while in Cpp

In this tutorial, we will learn about the triangle Number pattern using nested while in Cpp language.

We can use nested while loop in C++ to write coding for Squares, rectangles, Floyed triangle, Pyramid triangles and many other shapes.

In this tutorial, we will learn about some of the Floyd’s triangle shapes and how to write coding for that in C++ programming language.

Program to print triangle pattern using the number

Program 1

Floyd’s triangle number pattern 1

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    int rows;
    cout << "Floyd's triangle pattern" << endl;
    cout << "Enter the number of rows: ";
    cin>>rows;
    int i=1;
    while(i<=rows){//outer while loop
            int j=1;
    while(j<=i){//inner while loop
            cout<<j;
    j++;
    }
    cout<<"\n";
    i++;
    }
    getch();
    return 0;
}

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

Floyd's triangle pattern
Enter the number of rows: 6
1
12
123
1234
12345
123456

Program 2

Floyd’s triangle number pattern 2

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    int rows;
    cout << "Floyd's triangle pattern" << endl;
    cout << "Enter the number of rows" << endl;
    cin>>rows;
    int i=1;
    while(i<=rows){//outer while loop
            int j=1;
    while(j<=i){//inner while loop
            cout<<i;
    j++;
    }
    cout<<"\n";
    i++;
    }
    getch();
    return 0;
}

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

Floyd's triangle pattern
Enter the number of rows: 6
1
22
333
4444
55555
666666

Program 3

Floyd’s triangle number pattern 3

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    int rows;
    cout << "Floyd's triangle pattern" << endl;
    cout << "Enter the number of rows: ";
    cin>>rows;
    int row=1;
    int i=1;
    while(i<=rows){//outer while loop
            int j=1;
    while(j<=i){//inner while loop
            cout<<row<<" ";
            row++;
    j++;
    }
    cout<<"\n";
    i++;
    }
    getch();
    return 0;
}

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

Floyd's triangle pattern
Enter the number of rows: 6

1
2 3
4 5 6 
7 8 9 10
11 12 13 14 15
16 17 18 19 20 21

Program 4

Floyd’s triangle number pattern 4

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    cout << "Floyd's triangle pattern" << endl;
    int i=1,j,k,row=8,num=0;
    while(i<=row){//outer while loop
            int k=1;
    while(k<=row-(row-i)){//inner while loop
            cout<<" ";
            k++;
    }
    num=row-i;
    j=1;
    while(j<=num){
        cout<<row-(row-j);
        j++;
    }
    i++;
    cout<<"\n";
    }
    getch();
    return 0;
}

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

Floyd's triangle pattern
1234567
  123456
    12345
      1234
        123
          12
