In this tutorial, we will discuss the Cpp program triangle alphabet pattern using while loop
In this post, we will learn how to displayed Floyd’s triangle alphabet pattern using while loop or nested while loop in C++ programming language
here, we displayed some alphabet Floyd’s triangle program with coding using nested while loop and also we get input from the user using cin() function in C++ language
the user can provide numbers as they wish and get the alphabet pattern according to their input
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,rows;
cout << "Enter the number of rows" << endl;
cin>>rows;
cout<<"\n";
i=1;
while(i<=rows){
j=1;
while(j<=i){
cout<<(char)(i+64);
j++;
}
i++;
cout<<"\n";
}
getch();
return 0;
}
When the above code executed, it produces the following results
Enter the number of rows 6 A BB CCC DDDD EEEEE FFFFFF
Program 2
#include <iostream>
#include <conio.h>
using namespace std;

cout<<"\n";
i=1;
while(i<=rows){
j=1;
while(j<=i){
cout<<(char)(j+64);
j++;
}
i++;
cout<<"\n";
}
getch();
