Collapse Problem #2 Complete the class Problem2, the program does the following: • The program prompts the user to enter an integer. • The program continues to prompt the user for more integers as long as the sum of all values entered is between 1 and 50. • If the sum of all values entered is NOT between 1 and 50, Java the program stops taking integers, then display the value of sum. Here are two sample outputs, your output should look exactly the same as follows: Enter an integer: 23 Enter an integer: 1 I Enter an integer: -2 Enter an integer: 19 Enter an integer: -25 Enter an integer: 4 Enter an integer: 9 Enter an integer: -20 Enter an integer: -5 Enter an integer: -12 AK -8 lacBook Air
QI: tinclude (a) Write two different techniques to declare and initialize a variable with an example. using namespace std; void repchar(char, int); int main() (b) Write a program that simulates a simple cakulator. It reads two integers and a character. If the character is a +', the sum is printed; if it is a , the difference is printed: if it is a *", the product is printed; if it is a ", the quotient is printed; and if it is a %', the repchar(", 43): cout "Data type Range" endl; repchart-, 23). cout e "char-128 to 127" < endl
4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice. TarningsKast2 How many dices do you want to throw? 11 Which number do you want the probability for? The probability the get the number 11 with 4 dices is 7.19% Calculate
Python Programming Part 2 Direction: Use PYTHON to solve this problem. Description: This part tests for two things. The program must identify all resistors in series or in parallel with each other and calculate the equivalent resistance for each group of resistors. Recall that total resistance of resistors in series are added up while the total conductance of those in parallel are added up. Input Format: The first line of the input consists of 1 integer N which is the total number of resistors. The next N lines will consist of 3 strings and an integer R each separated by a space. The first string is the resistor name, the second and third strings are the node names where the resistor terminals are connected, and R is its resistance value. Output Format: One line for each group of resistors in series or parallel. Each line starts with a list of resistors arranged in lexicographical order (see Lexicographic order - Wikipedia) followed by their total resistance rounded off to the nearest…
Problem #3: Write code that divides a positive number n in half until the resulting number is less than 1. For this exercise, use a method that doesn't require you to convert the integer n to a different data type. For example, if n = 5, the first time through the loop should result in 2.5, the second time through should result in 1.25, and the third time through should result in 0.625. The loop should not be executed a forth time since 0.625 =10: 5 4 3 print (n) HN W 2 (missing line) n=n//10 1 print (r)

Q1: Can you read this question carefully rebug and type the answers Debug Problem 1: As an intern for The Weather Channel, you have been instructed to debug a java program that converts Celsius to Fahrenheit. If the formula runs correctly, then 12 degrees in Celsius should give 54 degrees in Fahrenheit . Here is the formula given and it might not be correctly stated in terms of () needed and the order of operations. Google a reputable site if needed.: °F = °C x 9/5 + 32 Remember that there may be more than one problem to fix. It could be that variables have an incorrect data type. It could be that the formula is not coded correctly. Also, some import statements could be missing. Copy and paste the code below in JGrasp and debug the code. Here is the code to debug: // Convert Celsius to Fahrenheit class CelsiusToFahr { public static void main (String args[]) { Scanner keyboard = new Scanner(System.in); int celsius = 0; int fahr = 0; System.out.println("Input the degrees in…
Assignment 1/ Reset to Starter Code 2. Problem 2: Product ID Numbers Saved Problem Description In this second problem, you will build on and extend the program created while solving the first problem. You will be expected to isolate both the product id number and company number from the barcode number of the item to be purchased by the customer. Input You will receive (from the user) the following as input (in order): • The first and last name of the customer (e.g., Eric Poitras) • The item to be purchased, identified through a barcode number (e.g., 1909238092) • The cost of the item to be purchased by the customer (e.g., 8.50) • The cash amount given by the customer (e.g., 10.00) Processing 1. Extract the product id and company id numbers 2. Print the data stored in each variable in the corresponding format Output 1. Customer (Last, First): {LAST} {FIRST} 2.
