Hello, I have a problem with understanding this line.
forEach(value.split("<br>"), line, line.trim()).slice(-3).join("\n")
This line is for the open refine program. Could you tell me what this line is trying to do? I have no idea what this is for...
For your information, this line appeared when professor was talking about 'Fetching and Parsing HTML'..
Thank you for answering my question and have a good day!
p.s. My professor told us to insert that line in the expression box and try to figure out what this expression means... As I'm not majoring in CS, it's too difficult for me to understand..;(

#include <stdio.h>
int main(void) {
int input = -1;
double average = 0.0;
/* Use this for your input */
scanf("%d", &input);
/* This is the only output you need */
printf("%.1lf", average);
return 0;
}
Please write a C coding program (make it simple coding) that find the average of sequence integer. when user enter integers, once at a time. Also, If the user enters 0 (zero), the code will calculates the average and then prints it, and then exits.

PQ1. How would you declare the following scalar and non-scalar (vector) variables?
PQ2.
PQ3.
PQ4. The algorithm for checking if a number is a prime is to check if it is divisible by any number less than itself other than 1. (Divisibility implies that if you use the modulus operator, %, the result will be 0). Write a function to check if a number is a prime.

1. Create a base class called Vehicle that has the manufacturer’s name (type String), number of cylinders in the engine (type int). Then create a class called Truck that is derived from Vehicle and has additional properties: the load capacity in tons (type double) and towing capacity in tons (type double).
Add the following methods to the Vehicle class:
Add the following methods to the Truck class:
Write a driver program that tests all your methods. Create at least two objects of truck class, and two objects of vehicle class.

Write a simple lottery program which can do the following:
1. asks the user to provide an integer value from 1 to 5
2. generates one random integer number from 1 to 5
3. display “You lost $1” if the two numbers are different, and display “You won $5” otherwise.the program asks if the user wants to continue playing the lottery.
If yes, the program repeats steps 1-3. If no, the program terminates.

Consider the following code:
values = [2, 5, 8, 12, 15]
values2 = {v % 3 for v in values}
What will be the length of values2?
Consider the following code:
values = ["moose", "giraffe", "antelope", "tortoise", "chinchilla"] values2 = [len(s) for s in values if "a" in s]
What will be the value of values2[1]?
Consider the following code:
numbers = [1, 2, 7, 9, 13] numbers2 = [n // 2 for n in numbers]
What will be the value of numbers2[2]?
