CPP program to print Floyd’s triangle number patterns

In this tutorial, we will discuss about CPP program to print Floyd’s triangle number patterns

In C++ language, we can write different Floyd’s triangle number pattern program using nested for loop.

To understand this pattern, you must know how for loop and nested for loop works in C++ language

C++ floyd’s triangle number pattern programs

Number pattern 1

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

int main()
{
    int i,j,row;
    cout<<"Enter the value for row :";
    cin>>row;
    cout << "The number floyd's triangle patterns" << endl;
    for(i=1; i<=row; i++ ){
        for(j=1; j<=i; j++ ){
        cout<<i<<" ";

    }
    cout<< endl;

    }
    getch();
    return 0;
}

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

Enter the value for the row: 8
The number Floyd's triangle pattern
1
22
333
4444
55555
666666
7777777
88888888

Number pattern 2

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

int main()
{
    int i,j,row;
    cout<<"Enter the value for row :";
    cin>>row;
    cout << "The number floyd's triangle patterns" << endl;
    for(i=1; i<=row; i++ ){
        for(j=1; j<=i; j++ ){
        cout<<j<<" ";

    }
    cout<< endl;

    }
    getch();
    return 0;
}

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

Enter the value for the row: 7
The number Floyd's triangle pattern
1
12
123
1234
12345
123456
1234567

Number pattern 3

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

int main()
{
    int i,j,k=1,rows;
    cout<<"Enter number of rows";
    cin>>rows;
    cout<<"You entered 8 \n here your triangle pattern\n";
    for(i=1; i<=rows; i++){
        for(j=1; j<=i; j++){
        cout<<k<<" ";
        k++;
    }
    cout<< endl;
    }
    getch();
    return 0;
}

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

Enter number of rows: 8
you entered 8
 here your triangle pattern
1
2  3
4  5  6
7  8  9  10
11 12 13 14 15
16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31 32 33 34 35 36

Number pattern 4

inverted floyd’s triangle pattern printing using nested for loop

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

int main()
{
    int i,j,rows;
    cout<<"Enter the number of rows you want :";
    cin>>rows;
    cout << "here your "<<rows << " number of rows floyd's triangle"<<endl;
    for(i=rows; i>=1; i--){
        for(j=1; j<=i; j++){
        cout<<j<<" ";
    }
    cout<<endl;
    }
    getch();
    return 0;
}

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

Enter number of rows you want: 8
here your 8 number of Floyd's triangle
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7
1 2 3 4 5 6
1 2 3 4 5 
1 2 3 4
1 2 3
1 2
1

Number pattern 5

floyd’s triangle pattern printing using for loop and while loop

#include <iostream>

using namespace std;

int main()
{
    int rows,n;
    cout<<"Enter the number of rows you want :";
    cin>>rows;
    cout << "Here number pattern is:" << endl;
    for(int i=1; i<=rows; ++i)
    {
        n=rows-i;
        while(n>0)
        {
            cout<<" ";
            n--;
        }
        for(int j=i; j>=1; j--)
        {
            cout<<j;
        }
        cout<<"\n";
    }
    return 0;
}

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