/* From this thread: https://www.sololearn.com/Discuss/752696/?ref=app !!!LOOK HERE!!! https://www.sololearn.com/Discuss/753514/?ref=app This class was created for access to the nth element of an array using [n] instead of [n-1] I'm creating an useless new type for replace arrays :) Just code 4 fun! version 0.1 - added internal pointer and [] overloading version 0.1.1 - added a proper constructor using dynamic memory allocation version 0.2 - added << overloading version 0.2.1 - added internal counter for store the number of elements version 0.2.2 - added public method for read the internal counter version 0.3 - now this is a template class */ #include using namespace std; template class Array { private: int numberOfElements = 0; T *ptr; public: // for now no copy Array(const Array&) = delete; Array& operator = (const Array&) = delete; // useless: no void array please Array() { ptr=nullptr; } // destructor ~Array() { delete [] ptr; } // right constructor Array(int n): numberOfElements(n), ptr(new T[n]) {} // return the numbers of element inserted in the array int howManyElements() { return numberOfElements; } // overload for [] operator T& operator[](int n) { if(n<=0) return ptr[0]; return ptr[n-1]; } // overload for << operator friend ostream& operator<<(ostream& os, const Array &a) { os << (T*)a.ptr; return os; } }; int main() { int a[10] = {0,1,2,3,4,5,6,7,8,9}; Array array{10}; for(int i = 1; i <=10; i++) array[i] = a[i-1]; for(int i = 1; i <=10; i++) cout << array[i] << endl; cout << array << endl; cout << array.howManyElements() << endl; cout << endl << endl << endl; char b[7] = {'a','b','c','d','e','f'}; Array array2{7}; for(int i = 1; i <=7; i++) array2[i] = b[i-1]; for(int i = 1; i <=7; i++) cout << array2[i] << endl; cout << array2 << endl; // this will print all the string because array2 is a char* cout << array2.howManyElements() << endl; /* Copy constructor and assignment operator are private Array sis = array; Array sis2{10}; sis2 = array; */ return 0; }
