Basic C Programming - Structure Operator

What is a structure in C programming?

• A structure in C programming is a type of loop

• A structure in C programming is a method for error handling

• A structure in C programming is a user-defined data type that allows you to group different data types together under a single name.

• A structure in C programming is a built-in data type

How do you define a structure in C?

• struct { member1; member2; ... };

• define structureName { member1; member2; ... };

• structureName { member1; member2; ... };

• struct structureName { member1; member2; ... };

Explain the process of initializing a structure in C.

• struct Person person1 = {"John", 25, "New York"};

• struct Person person1; person1.name = 'John'; person1.age = 25; person1.city = 'New York';

• Person person1 = new Person('John', 25, 'New York');

• struct Person person1 = {name: 'John', age: 25, city: 'New York'};

How can you access members of a structure in C?

• By using the semicolon (;)

• By using the hashtag (#)

• By using the dot operator (.)

• By using the exclamation mark (!)

What are nested structures in C?

• Nested structures in C are functions within structures.

• Nested structures in C are pointers within structures.

• Nested structures in C are structures within structures.

• Nested structures in C are arrays within structures.

Provide an example of defining a nested structure in C.

• struct Person { char name[50]; int age; struct Address { char street[50]; char city[50]; char state[20]; int zip; }; };

• struct Person { char name[50]; int age; struct Address { char street[50]; char city[50]; char state[20]; int zip; }; };

• struct Person { char name[50]; int age; struct Address { char street[50]; char city[50]; char state[20]; int zip; }; };

• struct Person { char name[50]; int age; struct Address { char street[50]; char city[50]; char state[20]; int zip; }; };

How do you access members of a nested structure in C?

• Use the dot (.) operator for each level of nesting in C.

• Use the arrow (->) operator for each level of nesting in C.

• Use the comma (,) operator for each level of nesting in C.

• Use the semicolon (;) operator for each level of nesting in C.

What is the syntax for accessing a member of a nested structure in C?

• outer.inner.data

• outer.inner.value

• inner.value.outer

• inner.outer.value

Explain the concept of structure pointer in C.

• Structure pointers in C are used to access and manipulate arrays through a pointer.

• Structure pointers in C are pointers that point to structures. They are used to access and manipulate structure members through a pointer.

• Structure pointers in C are used to access and manipulate strings through a pointer.

• Structure pointers in C are used to access and manipulate functions through a pointer.

How can you access members of a structure using a pointer in C?

• Use the '.' operator to access structure members.

• Use the '*' operator to dereference the pointer and access structure members.

• Use the '->' operator to dereference the pointer and access structure members.

• Use the '>>' operator to access structure members.
