“12 Fun C++ Console Programs for Beginners to Master Logic Building”

✅ Summary (for preview):

I created a console-based C++ application that helps beginners practice basic to intermediate-level problems like even/odd checks, factorials, primes, and more — all in one interactive menu. Here's the full explanation, code, and GitHub link.

💡 What I Built

As a beginner learning C++ and DSA, I often found myself jumping between problems. So I decided to create a menu-based console app that lets me practice 12 core concepts—all in one place!

From basic number operations to loops, conditionals, and recursion—this app helps build the logic muscles needed for problem-solving.

🛠 Features of the App

This project covers problems at 3 difficulty levels:

🔹 Beginner Level
1. Sum of two numbers
2. Even or odd check
3. Multiplication table
🔹 Intermediate Level
1. Factorial of a number
2. Prime number check
3. Sum of digits
4. Reverse a number
5. Maximum of three numbers
🔹 Advanced Level
1. nCr (combinations)
2. Prime numbers between two numbers
3. Print rectangle with default arguments
4. Exit

📸 Preview

🖥️ The app runs in the console with a clean menu UI using colors via rang.hpp. Users just enter a number (1–12) to access each problem interactively.

🔍 Code Example: Reverse a Number

Here’s a simple part of the code for reversing a number:

cpp code

void reverseNum( int n ) {

    for ( int k = n; k>0; k/= 10 ) {

            int a = k % 10;

            cout « a;

     }

     cout« endl;

}

It uses a loop to extract and print each digit in reverse.

Sample Output:

Factorial of a Number :-

Prints rectangle :-

Multiplication table : -

🧠 What I Learned

How to write modular functions in C++
Use of default arguments and function overloading
Improved my input validation skills
Practiced loops, conditionals, and basic math logic

🙋‍♀️ What's Next?

Add file handling to store previous results
Add level-based navigation
Possibly convert it to a GUI-based version using C++ libraries later
