C++ programs to print alphabet pattern

Introduction

In this article, we will analyze a C++ code snippet that prints a pattern based on user input. The code prompts the user to enter a number and then generates a pattern using alphabets. We will break down the code, explain its key concepts, and provide code examples for better understanding.

Key Concepts

Before diving into the code, let's familiarize ourselves with some key concepts:

• Input and Output: The code uses the cin and cout objects from the iostream library to read user input and display output on the console, respectively.
• Loops: The code utilizes nested for loops to generate the pattern. The outer loop controls the number of rows, while the inner loop determines the number of characters in each row.
• Type Conversion: The code uses type conversion to convert integers to characters. It uses the (char) cast to convert the integer value to its corresponding ASCII character.

Code Structure

#include <iostream>
using namespace std;

int main() 
{
   int num;
   cout<<"Enter Number : ";
   cin>>num;
   for(int i=1;i<=num;i++)
   {
       for (int j=1;j<=i;j++)
       {
           cout<<(char)(j+64);
       }
       cout<<endl;
   }
    return 0;
}
