C Programming Structures and Pointers

What is the purpose of a structure in C programming?

• It is used to define a new data type that can contain different types of variables.

• It is a type of function in C programming.

• It is a keyword used for conditional statements in C programming.

• It is a type of loop in C programming.

What is the correct operator to access elements of a structure using pointers in C programming?

• Use the dot operator (.)

• Use the asterisk operator (*)

• Use the hash operator (#)

• Use the arrow operator (->)

What is the purpose of using an array within a structure in C programming?

• To allow for storing multiple elements of different data types within a single structure.

• To restrict the structure to store only a single element of a specific data type.

• To prevent access to the array within the structure using index notation.

• To enable storing multiple elements of the same data type within a single structure.

Which of the following is the correct syntax for declaring an array of structures in C programming?

• student[10] struct;

• int student[10];

• struct student students[10];

• struct students[10];

How do you declare a pointer to a structure in C programming?

• struct *ptrName = structureName;

• ptrName = &structureName;

• struct structureName *ptrName;

• struct ptrName = &structureName;

Explain the concept of pointer to structure in C programming with an example.

• Example: struct student { int id; char name[20]; }; struct student s1; struct student *ptr; ptr = &s1; // Accessing structure members using pointer ptr->id = 1; strcpy(ptr->name, "John");

• struct student *ptr; ptr = &student s1;

• ptr->id = 1; ptr->name = 'John';

• struct student s1; struct student *ptr; ptr = s1;

How does using arrays in C programming help in efficiently storing and accessing multiple elements of the same data type?

• By allowing for easier manipulation of data

• By providing a way to perform complex calculations

• By enabling the creation of user-friendly interfaces

• By facilitating the organization and retrieval of related data

What is the correct way to pass an array to a function in C programming?

• Pass the array name as an argument to the function

• Pass each element of the array as a separate argument to the function

• Convert the array to a string and pass it as an argument to the function

• Use a pointer to the array as an argument to the function

What are the different operations that can be performed using conditions in C programming with respect to arrays?

• Conditions in C programming can only be used with single variables, not arrays

• Conditions in C programming are not applicable to arrays

• Conditions in C programming can be used with arrays to perform different operations based on specific criteria, such as checking for the existence of an element, filtering elements, or performing different operations based on array values.

• Conditions in C programming cannot be used to filter elements in arrays

What is the purpose of using functions in C programming?

• Functions in C programming are used to perform a specific task and can be called multiple times from different parts of the program

• Functions in C programming are only used for printing the output of a program

• Functions in C programming are used to skip certain parts of the program

• Functions in C programming cannot be used to perform repetitive tasks
