Program Plan Intro
Recursive Multiplication
Program Plan:
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the main () function.
- Call the method “recurmultiplication()” to compute the product of the given element by passing two values as its arguments.
- The function call gets executed in recursive way to compute the product of the given values.
- Define the “recurmultiplication()” method,
- The condition gets validated to check whether the given value is 1 and will return the product by returning the value of “y”.
- The condition validates the value to be greater than 1, the product value is returned after computing the product of all elements that is present by performing repeated addition.

Recursive Multiplication
Design a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition as follows:
7×4=4+4+4+4+4+4+4(To keep the function simple, assume that x and y will always hold positive nonzero integers.)
Recursive PrintingDesign a recursive function that accepts an integer argument,n , and prints the numbers 1 up through n .
2. Sum: a recursive function that computes the sum of integers 1, 2, 3, …., n for a given number n.
So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)

- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forwardRecursive Multiplication Design a recursive function that accepts two arguments into the parameters x and y.

IN Q BASIC LANGUAGEarrow_forward(C Language) Write a recursive function called DigitCount() that takes a non-negative integer as a parameter and returns the number of digits in the integer. Hint: The digit count increases by 1 whenever the input number is divided by 10.arrow_forward
- Python program (recursive function) A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result. Write a python recursive functionprod that takes x as an argument, and returns the result where, result=1*1/2*1/3*….*1/n Include a screenshot that shows a python program that uses the above function and prints the rounded result to three decimal placesafter prompting the user to enter a number, x. Use x=3. N.B: The code should be included please.arrow_forwardRecursive Exponentiation (using c language) Write a recursive function power(base, exponent) that when invoked returns baseexponent. For example, power(3, 4) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than or equal to 1. Then, write a demo program that uses the power function and test it out for a number of inputs. Hint: The recursion step would use the relationship baseexponent = base * baseexponent–1 and the terminating condition occurs when exponent is equal to 1 because base1 = basearrow_forwardJava C++ Write a recursive function that accepts two arguments into the parameters x and y.

- Drawing a right side up triangle Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn. Ex: If the input of the program is: 3 the function DrawTriangle() outputs: * *** Ex: If the input of the program is: 19 the function DrawTriangle() outputs: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* Note: No space is output before the first '*' on the last line when the base length is 19. in c++arrow_forward1. Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:********************Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern. 2. A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameter.arrow_forwardWrite a recursive function that converts a decimal number to binary number.int DecToBin(int dec);arrow_forward
