C Language Intermediate Quiz

1. Explain the difference between a structure and a union in C language.

• A structure is used for storing single data type, while a union is used for storing multiple data types

• A structure and a union are the same thing in C language

• A structure is a collection of variables of different data types under a single name, while a union is a special data type that allows storing different data types in the same memory location.

• A structure can only store integers, while a union can store any data type

2. What is the use of typedef in C language? Give an example.

• To create an alias for a data type.

• To create a new variable

• To define a function

• To perform mathematical operations

3. Write a C program to demonstrate the use of structures and unions.

• struct and union are not used in C programming

• C programs cannot use structures and unions

• Structures and unions are only used in C++

• struct and union are used to demonstrate the use of structures and unions in a C program.

4. What is the difference between an array and a string in C language?

• Arrays are a collection of characters, while strings are a collection of similar data types.

• Arrays and strings are the same thing in C language.

• Arrays can only store integers, while strings can store any type of data.

• Arrays are a collection of similar data types, while strings are a collection of characters.

5. Explain the concept of pointers in C language with respect to arrays and strings.

• Pointers in C language are used to perform mathematical operations on arrays and strings

• Pointers in C language are used to create new arrays and strings

• Pointers in C language are used to access elements and characters in arrays and strings indirectly

• Pointers in C language allow direct access and manipulation of array elements and string characters by storing their memory addresses.

7. What is the difference between a function and a recursive function in C language?

• A recursive function calls itself, while a regular function does not.

• A recursive function can only return a single value, while a regular function can return multiple values.

• A regular function can only be called once, while a recursive function can be called multiple times.

• A recursive function calls another function, while a regular function calls itself.

8. Explain the concept of recursion with an example in C language.

• Recursion in C language is when a function calls itself to solve a problem. For example, a factorial function can be implemented using recursion in C.

• Recursion in C language is not supported by the compiler.

• Recursion in C language is used to create loops within a program.

• Recursion in C language is when a function calls another function to solve a problem.

9. Write a C program to find the factorial of a number using recursion.

• The correct answer is to write a Python program to find the factorial of a number using recursion.

• The correct answer is to write a C program to find the factorial of a number using recursion.

• The correct answer is to write a C++ program to find the factorial of a number using iteration.

• The correct answer is to write a Java program to find the factorial of a number using recursion.

10. What are the different types of operators in C language? Explain with examples.

• Arithmetic, Relational, Logical, Bitwise, Assignment, Miscellaneous

• Addition, Subtraction, Multiplication, Division

• If, Else, Switch, Case

• Comparison, Concatenation, Exponentiation, Modulus

11. Write a C program to demonstrate the use of bitwise operators.

• Write a Python program instead of a C program

• Use bitwise operators in a C program to demonstrate their functionality.

• Demonstrate the use of conditional statements instead of bitwise operators

• Use arithmetic operators instead of bitwise operators
