Define a Haskell program that contains a function main :: 10 () . When executed the program should read one line after the other (via getLine ). It should stop its execution when reading an empty line, and then prints the lines with line-numbers attached. Here is an example dialog. All lines after the empty line have been printed by the program. Hello, this is some text. (empty line) 1 of 3. Hello, 2 of 3. this is some 3 of 3. text.

- I am getting an Null pointer exception but after that i have an important code that i want to run in any condition. Please handle this in Java programming language.Implement in C Programming 8.2.2: Printing with pointers. If the input is negative, make numItemsPointer be null. Otherwise, make numItemsPointer point to numItems and multiply the value to which numItemsPointer points by 10. Ex: If the user enters 99, the output should be:Items: 990 #include <stdio.h> int main(void) { int* numItemsPointer; int numItems; scanf("%d", &numItems); /* Your solution goes here */ if (numItemsPointer == NULL) { printf("Items is negative\n"); } else { printf("Items: %d\n", *numItemsPointer); } return 0;}Give solution in C ++ Language with secreenshoot of source code. Part 01In this task, you need to do the following:• Write a function named displayMessage() that takes user name as input in character array and then shows greetings• Now take the name input in main() and pass the name as an argument to displayMessage() function• Change the displayMessage() method such that it returns the number of characters after displaying the greetings part 02Write a function power that takes two parameters a and b. And it returns the power as ab.
- Please implement the follwoing problem in C++: Implement a symbol balance checker function for the Pascal programming language. Pascal allows for the following pairs: {}, (), [], begin end . All programs will begin with the word "begin" and end with the word "end". Your function should receive an ifstream object which is already open and will return true, all of the symbols match, or false, they do not. You do not have to worry about comments in the program but you do have to avoid other parts of the program's code such as assignment statements (x=y) and other expressions.Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 2. Write a recursive function that reads words from the standard input stream and displays them in reverse order on the standard output stream. For example, if the input was: here comes the sun, the output would be: sun the comes here. Hint: Read individual words until the end of a sentence is reached. You can determine the end of the sentence any way you like. Some suggestions include (a) checking the last character of a word for a sentence terminator (. ? ! ) (b) Using a keyword such as 'quit' to indicate the end of input. (c) Using the eof method of the cin object. (ctrl Z for windows or ctrl D for others can be used to force an end of file from the keyboard.)Write the C++ full main.cpp for the first screenshot titled, "Project 25.1" Then write full main.cpp mystring.h, and mystring.cpp for the second screenshot titled, "Project 25.2"
- Provide JAVA source code with proper comments for attached assginment.Please fill in the blanks. Programing language is C. /*For simplicity, this program will get the information of each client, and print it right back. We could get the information of all clients first, then print them all later for better readability using an array of struct.*/ #include<stdio.h> #include<stdbool.h> #define length 70 //assume there's no names longer than 70 /*It's good practice to add all function headers to the top of the program*/ __1__ __2__ getEmployeeInfo(); __3__ printEmployeeInfo(__4__ __5__ em); __6__ __7__ getClientInfo(__8__ i); __9__ printClientInfo(__10__ __11__ cli, __12__ i); /*Employee struct: all the arrays use the same constant size defined on top name-first, last-(string) title (string) number of clients (integer) number of years working at the company(can take decimal points). */ __13__ employee { __14__ first_name[__15__]; __16__ last_name[__17__]; __18__ title[__19__]; __20__ num_clients;…INSTRUCTIONS: Write a C++ script/code based on the problem below. RESISTANCE PROBLEM: For your first OOP computer code, you are to create a code containing class for the solution of resistor problem for a purely series and purely parallel electric circuit. The user will input three resistance values R1; R2; and R3 in ohms; and the program will provide an output of its resistance combination in series (Rs) and parallel (Rp).
- Write the following program in Racket: Remember there are no loops in a pure functional language so anything you need to do multiple times must be done using recursion. Write a function dates_in_month that takes a list of dates and a month (i.e., an int) and returns alist holding the dates from the argument list of dates that are in the month. The returned list shouldcontain dates in the order they were originally given. To make your life easier you may want to write an append function to be used in this one. It should take two list and append the second onto the first. Include your test cases please3. A chess board is an 8x8 matrix of squares. Each square can be empty or occupied by a chess piece. Write a class for a chess board. In the class, write a function that puts a chess piece into the position given as a parameter. The position can be given as numbers 0..7, 0.7. Note: I need an answer on C++ code.. please do it fastImplement the following functions in the same application in C#: 1. Given a number (integer) N (greater than 1). Implement a Fibonacci sequence of length N. (Function name ComputeFibonacciSequence )ComputeFibonacciSequence receives N.2. Given a list L with n numbers (integers), implement a function that returns whether that list is even prone or not (i.e.: the number of even numbers in the list must be higher than that of the odd numbers.) (Function name ComputeEvenProne) - Return 1 if the list is even prone, return 0 if it is not.ComputeEvenProne receives L.
