Cpp program to print triangle alphabet pattern

Cpp program to print triangle alphabet pattern

In this tutorial, we will discuss a concept of Cpp program to print triangle alphabet pattern using for loop in C++ language.

here, we displayed 15 alphabet Floyd’s triangle program with coding and using nested for loop and also we get input from user using cin function.

the user can provide numbers as they wish and get the alphabet pattern according to their input

Java program to display triangle alphabet pattern

Floyd’s Triangle Alphabet Pattern 1

Program 1

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

int main()
{
    int i,j,rows;
    cout << "Enter number of rows: ";
    cin>>rows;
    cout << "\nHere your pattern\n\n";
    for(i=1; i<=rows; i++){
        for(j=1; j<=i; j++){
        cout<<((char)(i+64));
    }
    cout<< endl;
    }
getch();
    return 0;
}

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

Enter number of rows: 6

Here your pattern
