🧩 C++ Utility Library — clsPrint & clsInputValidate

A modern and reusable C++ helper library for efficient console output and robust input validation.
It provides two key classes:

• 🖨️ clsPrint — for printing and formatting data beautifully in the console.
• ✅ clsInputValidate — for validating user input of any type safely and interactively.

---

✨ Overview

🔹 clsPrint:
Enables clean, readable, and feature-rich console printing — from text formatting and random data generation to mathematical pattern output.

🔹 clsInputValidate:
Handles user input safely, checking for type errors, number ranges, positivity, odd/even/prime/perfect/palindrome properties, and more.

Numbers	Print digits, Fibonacci, even/odd/prime/palindrome/perfect numbers
Random	Generate random uppercase, lowercase, and special characters
Math Integration	Uses clsMath for prime, palindrome, and perfect checks
Files	Save strings to text files easily
Console Effects	Change screen colors, alerts, and game result screens
Dates	Print short day/month names and formatted week headers

✅ clsInputValidate

Category	Description
Type Validation	Check if last input was valid
Range Checking	Ensure number lies between two values
Positive/Negative	Read only positive or negative numbers
Odd/Even	Read numbers constrained by parity
Prime/Perfect/Palindrome	Validate based on mathematical properties
Characters & Strings	Read single characters and full strings
Arrays	Read arrays of numbers, strings, or characters
Enum Input	Read operation types and difficulty levels safely

⚙️ Example Usage (main.cpp)

#include #include "clsPrint.h" #include "clsInputValidate.h" using namespace std;

int main() { clsPrint::Print("Hello from clsPrint!\n"); cout << clsPrint::Tabs(2) << "Indented text example\n";

cout << "Prime numbers from 1 to 20: ";
clsPrint::PrintPrimeNumbers(1, 20);

cout << "Perfect numbers from 1 to 500: ";
clsPrint::PrintPerfectNumbers(1, 500);

cout << "\nRandom upper letters: ";
clsPrint::PrintRandomUpperLetters(5);
cout << endl;

clsPrint::PrintFirstLetterOfWords("Hello World From clsPrint");
clsPrint::PrintVowels("Programming is Fun!");
clsPrint::SaveStringToFile("output.txt", "Saved line example.");

cout << "\nEnter a number between 1 and 10: ";
int num = clsInputValidate::ReadNumberBetween<int>(1, 10);
cout << "✅ You entered: " << num << endl;

cout << "Enter a positive number: ";
int pos = clsInputValidate::ReadPositiveNumber<int>();
cout << "✅ Positive number accepted: " << pos << endl;

cout << "Enter a prime number: ";
int prime = clsInputValidate::ReadPrimeNumber<int>();
cout << "✅ Prime number accepted: " << prime << endl;

return 0;

}

🧪 Sample Output

Hello from clsPrint! Indented text example Prime numbers from 1 to 20: 2 3 5 7 11 13 17 19 Perfect numbers from 1 to 500: 6 28 496 Random upper letters: QWTRB

First Letter of this string H W F C

Vowels In String are : o a i i u

Enter a number between 1 and 10: 7 ✅ You entered: 7 Enter a positive number: 15 ✅ Positive number accepted: 15 Enter a prime number: 13 ✅ Prime number accepted: 13
