Good Programming practices help in improving programs readability and understandability both for a programmer and for a general user. What changes would you make in the following program, written by a beginner, keeping in view the good programming practices.You are also required to write the output of the program if a user wants to find factorial of number 6.Note: The Program finds/calculates factorial of a number using a userdefined recursive function.#include<iostream> using namespace std;int f(int n);int main() {int n;cout << "Enter: "; cin >> n;cout << "Answer = " <<factorial(n);return 0;}int f(int n) {if(n > 1)return n * f(n - 1);else return 1;
}

- Please solve itarrow_forwardQuestion 9 Write in Python! Write a function word count that will take a sentence (string) and return to you the number of words in the sentence. Show it works by calling it with “Cinderella must get to the ball without her slippers.” (Answer should be 9) Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this linearrow_forwardPYTHON *Make sure to include only the one function in your file and please explain where the variables come from and what they represent please. In this problem, you should write one function named get_highest_sum. This function should have one parameters, a 2D list of numeric values. This should should look at every pair of integers in each row, and return the highest sum. For instance, the code: grid = [[5, 4, 3, 2, 1], [7, 2, 9, 1, 2, 0, 9, 9], [1, 2, 1, 2, 0]] result = get_highest_sum(grid) print(result) Should print 18 Due to the 9 next to another 9 on the second row.arrow_forward

- C codearrow_forward[Python (py3)] Displayed below is a code for matrix addition. However, there is an error that should be fixed in the code. The error in the code below is if the number of rows of the matrix is not equal to the number of columns of the same matrix, matrix addition will not be performed. This should not be the case so please fix this error. The only requirement for matrices addition is that the dimension of Matrix A is equal to the dimension of Matrix B, regardless if the number of rows of Matrix A and Matrix B is equal to the number of columns of Matrix A and Matrix B, respectively (see sample input and output below).Please resolve the error in the code below such that Matrix A and Matrix B can be added if the dimension of Matrix A is equal to the dimension of Matrix B. PLEASE do not just copy the code below and use it as the answer itself. I've encountered such case many times. Please modify the code.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */}}arrow_forward
