I finished this project and now I'm trying to do it in a different wayy to understant operators better.This is my main :

int main() { Uint a(10); cout << "Constructeur avec size_t OK "; Uint b; cout << "Constructeur vide OK "; b = 3; cout << "Affectation OK "; const Uint c = 13; cout << uint64_t(c) << " = 13: cast explicite vers uint64_t "; 

}

This is my class Uint,hpp

#include  using namespace std; class Uint { private: char *str; public: // Constructors Uint(); // Default constructeur Uint(size_t n); // Constructeur avec size_t explicit operator uint64_t() const; //Cast explicite ~Uint(); 

};

This is my Class Uint.cpp

using namespace std; //No args constructor Uint::Uint() : str(nullptr){ str = new char[1]; *str='\0'; } Uint::Uint(uint64_t n){} //I need an answer Uint::operator uint64_t ()const{} //I need an answer Uint::~Uint() { if(str == nullptr) { } else{ } delete[]str; }

Can someone tell me how to convert a int to char *str and return it ?
