Pointer in C++: A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows: type var-name; Here, “type” is the pointer’s base type and “var-name” is the pointer variable name. The asterisk is used to designate a variable as a pointer. The delete operator: The delete operator is used to destruct the object that is created with new by deallocating the memory associated with the object. The syntax of delete operator is as follows: [] delete cast-expression [] delete[] cast-expression In the above statement, the “cast-expression” argument must be a pointer to a block of memory previously allocated for an object created with the new operator. Given code: The following code is used to create a dynamic array. int entry; //Initialise pointer entry = new int[10]; //create a dynamic array
