APSIPA Understanding Recursive Calls

1. Introduction to Recursive Calls in C LanguageIn C, recursion refers to the process where a function calls itself in order to solve smallernstances of a problem. A recursive function typically has two main components:

1. Base case: The condition that stops the recursion to prevent infinite calls.
2. Recursive case: The part where the function calls itself with modified

parameters.A common example of recursion is the calculation of factorials or Fibonacci numbers.Here's a basic example of a recursive function in C:In this example:

• The base case is when n == 0 or n == 1, where the recursion stops.
• The recursive case is when the function calls itself with n - 1.

Quiz: Understanding Recursive Calls Here are two quizzes to test your understanding of how a recursive function works.

Below are C program that contains a recursive function. Predict the output for n = 3.2. Write a program to create a single linked list with four nodes. Each node represents auser containing the name and the age of this user.Example:Input:Output:3. Fill in the blanks or complete the following program to make it work as described. Output:

Length of str1: 6

Concatenated string (str1 + str2): APSIPA ASC 2024

Comparison result (strcmp(str1, str4)): -1 (since "APSIPA" is lexicographically smaller than "apsipa")

Converted integer + 10: 52

Copied string into str1: ASC 2024lease briefly describe what the run time error is in C language.

2. Write a program that prints each command-line argument on a new line.Example: Input in CMD: ./program hello worldOutput:

3. Write a program that reads a line of text from the user using fgets and prints itback.

Example: Input from the keyboard:

Output to the screen:

4. Write a program that reads a line of text using fgets and calculates its length

(excluding the newline character).

Example:

Input from the keyboard:

Output to the screen:5. Define a structure Rectangle代写APSIPA  Understanding Recursive Calls   with two members: length and width. Ask the user to input the length and width of a rectangle. Calculate and output the area and perimeter of the rectangle. Input:

Output:

6. Define a structure Student with the following members:name (a string) roll_number (an integer) marks (a float)

Write a program to:

Declare an array of 3 Student structures.

Ask the user to input the details of each student.

Print the name and marks of the student with the highest marks.
