Chapter 11: Problem 18

The _________ operator allows you to access structure members.

Short Answer

Expert verified
Answer: The dot (.) operator is used to access structure members in most programming languages. To use it, you simply append the member name to the structure variable with the dot operator in between them, like this: structure_variable.member_name. For example, in a C/C++ structure called "Student" with members "id" and "name", you can access these members using the dot operator as follows: s1.id and s1.name.

Step by step solution

01

Identify the operator

The dot (.) operator allows you to access structure members in most programming languages.
02

Create a sample structure

Let's create a sample structure in C/C++ to demonstrate the usage of the dot operator. ```c #include typedef struct { int id; char name[100]; } Student; ```
03

Access the structure members using the dot operator

Now, let's create a variable of type Student and access its members using the dot operator. ```c int main() { Student s1; s1.id = 1; strcpy(s1.name, "John Doe"); printf("Student ID: %d\n", s1.id); printf("Student Name: %s\n", s1.name); return 0; } ``` In the above code, 's1' is a variable of type 'Student'. We can access its members 'id' and 'name' using the dot operator. 's1.id' represents the 'id' member of the 's1' structure, and 's1.name' represents the 'name' member of the 's1' structure.
