Chapter 13: Problem 27

Members of a class object may be accessed through a pointer to the object by using the _________ operator.

Short Answer

Expert verified

Answer: The operator used to access members of a class object through a pointer is the arrow operator "->". It is used by placing it between the pointer variable and the member that needs to be accessed. For example, if we have a class "SampleClass" with a member variable "sampleVar" and a pointer "classPtr", we can access "sampleVar" using "classPtr->sampleVar".

Step by step solution

Identify the operator

The operator needed to access members of a class object through a pointer is the arrow operator "->".

Illustrate its usage

Given a class named 'SampleClass' that contains a member variable 'sampleVar', we can access it through a pointer using the arrow operator. Here's an example in C++: ```cpp #include using namespace std; class SampleClass { public: int sampleVar; }; int main() { SampleClass* classPtr = new SampleClass(); classPtr->sampleVar = 10; cout << "Value of sampleVar: " << classPtr->sampleVar << endl; delete classPtr; return 0; } ``` In this example, we created a pointer named 'classPtr' to point to a new instance of the 'SampleClass' object. We then used the arrow operator '->' to access the 'sampleVar' member variable and assigned it the value of 10. Finally, we printed the value of 'sampleVar' using the same arrow operator '->'.
