RndGenerator class in c++

[Gerald Bates]

I do not understand how to take my previous code in c and turn it into a C++ class due to my lack of knowledge on container classes. Would someone be kind enough to help me so I can study/test the final code. I've made everything obvious in what I am trying to achieve, also placed everything in the header for now.

#pragma once


#include <array>
#include <random>
#include <vector>


	class RndGenerator
	{
	public:
		RndGenerator(int MinNum, int MaxNum, int NumAmount, bool AllowRepeatedNum);		


	private:
		void GenerateNumbers();
		void ResetNumberStatus();
		int  PrintRndNumbers() const;


	private:
		int  m_MinNum {0};				// The Minimum number allowed to be generated.
		int  m_MaxNum {0};				// The Maximum number allowed to be generated.
		int  m_NumAmount {0};				// Amount of numbers to be generated.
		bool m_AllowRepeatedNum {false};	// Allow numbers to be repeated?, true/false.


		//std::array<bool> m_NumberStatus;  // Has number been generated already?, true/false.
		std::vector<int> m_RndNumber;		 // The random number generated.
	};


	RndGenerator::RndGenerator(int MinNum, int MaxNum, int NumAmount, bool AllowRepeatedNum)
	{
		// Automatically seed numbers.
		//srand((unsigned int) time(nullptr));  // Legacy c.


		// How to in c++
		//std::random_device rd;  // Seed for the random number engine
		//std::mt19937 gen(rd()); // Mersenne Twister engine
	}


	void RndGenerator::GenerateNumbers()
	{
		// How to with (using containers)


		//	ResetNumberStatus();
		// 
		//  int NumberValidCount = 0;
		// 
		//	   while (NumberValidCount <= m_NumAmount)
		//         std::uniform_int_distribution<> Number(MinNum, MaxNum); // Range


		//	       if (m_AllowRepeatedNum == false && m_NumberStatus[Number] == false ) // Not already generated
		//             push/emplace Number into m_RndNumber
		//				m_NumberStatus[Number] == true // Mark as generated
		//				NumberValidCount++
		//		   else
		//			   push/emplace Number into m_RndNumber
		//             NumberValidCount++


	}


		void RndGenerator::ResetNumberStatus()
		{
			// Use an iterator to reset m_NumberStatus[m_NumAmount] = false
		}


	int RndGenerator::PrintRndNumbers() const
	{
		// Use an iterator to print std::vector<int> m_RndNumber;
		// Get the size of vector and iterate all numbers to print.
	}

Not a class but this illustrates how to use c++ random numbers

Thanks, I will look at this.
