C++ Program to Alphabet triangle pattern using do-while loop
C++ program to Alphabet triangle pattern using the do-while loop
In this article, we will discuss the concept of C++ program to Alphabet triangle pattern using the do-while loop
We can print various type of number, asterisk, binary patterns using for, while and do-while loop in C++ programming language
In this post, we will discuss how to write a program to print different alphabet triangle pattern using the do-while loop in C++ language.
To understand this example programs, you should have previous knowledge of following C++ topics
Nested do while loop in C++ language
Code to Alphabet triangle pattern 1
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,rows;
cout << "Enter the number of rows:" << endl;
//get input from the user for number of rows
cin>>rows;
cout<<"\n";
cout<<"Here, your pattern\n";
i=rows;
do{
j=1;
do{
cout<<((char)(j+64));
j++;
} while( j<=i);
cout<<"\n";
i--;
}while( i>=1);
getch();
return 0;
}
When the above code is executed, it produces the following results
