A function which calls itself is called as recursion.

Hence, the correct answer is option “C”.

Expert Solution & Answer

Explanation of Solution

Recursion:

Recursion is a process where function is called again and again by itself for a specific number of times.

  • There are two types of recursive functions. They are as follows:
    • Direct recursion
    • Indirect recursion

Direct recursion:

When a function calls the same function repeatedly until the condition becomes false, then it is called as direct recursion.

Indirect recursion:

When a function calls another function which in turn calls the same calling function, then it is called as indirect recursion.

Example:

Consider the following example; the function “Add()” can be called itself in the same function definition. Hence, it comes under direct recursion.

#Define the Add()function

def Add()

         #Print the message

         print('Example of recursive function!!')

         #Call the Add() function recursively

         Add()

Explanation for wrong options:

A recursive function cannot call the different function.

Hence, option “A” is wrong.

A recursive function cannot halt the program.

Hence, option “B” is wrong.

A recursive function can call more than once in a program.

Hence, option “D” is wrong.

JAVA CODE PLEASE Recursive Functions Practice ll by CodeChum Admin Create a recursive function named factorial that accepts an integer input as a parameter. This calculates the factorial of that integer through recursion and return it. In the main function, call the factorial function and assign the value to a variable. Print the value in the next line. Input 1. One line containing an integer Output Enter·a·number:·4 24
Problem Statement for Recursive Sum of Numbers Program Here is a simple recursive problem: Design a function that accepts a positive integer >= 1 and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 10 is passed as an argument, the function will return 55. Use recursion to calculate the sum. Write a second function which asks the user for the integer and displays the result of calling the function. Part 1. Understand the Problem To design a recursive function, you need to determine at least one base case (the base case returns a solution) and a general case (the general case calls the function again but passes a smaller version of the data as a parameter). To make this problem recursive think about it like this: If the integer is 1, the function will return 1. If the integer is 2, the function will return 1 + 2 = 3. If the integer is 3, the function will return 1 + 2 + 3 = 6. . . . For this problem, we will be sending in the "last"…
