- True or False When a variable is declared in the initialization expression of a for loop, the scope of the variable is limited to the loop.In Java, If a semicolon is placed at the end of a for statement, the action of the for loop is empty. True or FalseWhich of the four parts of an information system would you wish to characterise best?
- Find the output of a = int a = 1; LOOP: 5 po do { if( a > 10) { a = a + 1; goto LOOP; } cout << "value of a: " << a « endl; a = a + 1; } While ( a < 20 ); *Q2/ The value of Y is 1 3 5 Y = - X X³ X5 Xn the following code calculates the value of Y, read the code carefully and program the same idea using the while loop. #include #include int main() { double x,y; int n; cout >x>>n; int i,k; k=0; y=0; for (i=1;iIt wont display the order total // JumpinJava.cpp - This program looks up and prints the names and prices of coffee orders. // Input: Interactive // Output: Name and price of coffee orders or error message if add-in is not found #include <iostream> #include <string> using namespace std; int main() { // Declare variables. string addIn; // Add-in ordered const int NUM_ITEMS = 5; // Named constant // Initialized array of add-ins string addIns[] = {"Cream", "Cinnamon", "Chocolate", "Amaretto", "Whiskey"}; // Initialized array of add-in prices double addInPrices[] = {.89, .25, .59, 1.50, 1.75}; bool foundIt = false; // Flag variable int x; // Loop control variable double orderTotal = 2.00; // All orders start with a 2.00 charge // Get user input cout << "Enter coffee add-in or XXX to quit: "; cin >> addIn; // Write the rest of the program here. while(addIn != "XXX") //loop until user…(16) 6. You want to write a Java application that creates a while loop that runs until the user enters a 0 as input. Each time the while loop runs, it displays a menu of three choices as will be shown in the sample run below. When the program reads in the user's choice, that choice should be read in as a String called choiceStr. Then, choiceStr should be converted into an int called choice by using the code below: int choice Integer.parseInt(choiceStr); If the user enters a 1 for choice == 1, the program will print "Choice 1" to the screen. If the user enters a 2 for choice == 2, the program will print "Choice 2" to the screen. Here is a sample run: 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 1 Choice 1 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 1 Choice 1 0 to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 2 Choice 2 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 0Pre-Lab 02: Write a menu driven C++ program that uses do- while loop with a switch-statement to evaluate whether the user wants to find a square of a value, find the cube of a value, or quit the program. After the user makes their choice, the required numbers needed for the operation are input and the user's result of choice is computed and printed. The program ends when the user chooses to quit from the program. If the user entered an invalid choice print an ERROR message and show the menu again. +,2. Find the execution time of the nested 'for' loop given below. #include using namespace std; int main() { int x = 20,sum=0; for(int i=x;i>=0;i--X for(int j=i-1;j>=0;j--X sum = sum+j; } } cout<#include<stdio.h> void main(){// variables to store input values for account balance and interest ratefloat balance, rate;// variables to store option and choice inputint option, choice;int i, j; // loop counters // outer loop to allows the user to repeat this calculation for a new balance and interest ratewhile(choice != 0){// asking and storing user inputprintf("Bank Account Balance: ");scanf("%f", &balance);printf("Interest Rate: ");scanf("%f", &rate); // printing mod menu and storing input for thatprintf("Mode Menu\n [1] Annually\n [2] Monthly\n");printf("Option: ");scanf("%d", &option); // if selected option is 1if(option == 1){// printing mode selectedprintf("Annually Interest\n");// for 5 yearsfor(i=1; i<=5; i++){// computing balance by adding interestbalance = balance + balance*rate/100.0;// printing balanceprintf("Bank Account Balance in Year %d: %.2f\n", i, balance);}}// if option 2 is selectedelse if(option == 2){// printing mode selectedprintf("Monthly…Is it real or not?
