Answer:
Here is the calcPrice.c program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main method
int itemNo, month, day, year, quantity; //declares variables to hold item number, quantity, and date
float unitPrice; //declare variable to hold price per unit
printf("Enter item number: "); // prompts user to enter item number
scanf("%d", &itemNo); //reads item number from user and stores it in itemNo variable
printf("Enter unit price: "); // prompts user to enter unit price
scanf("%f", &unitPrice); //reads input unit price and stores it in unitPrice variable
printf("Enter quantity: "); //prompts user to enter quantity
scanf("%d", &quantity); //reads input quantity and stores it in quantity variable
printf("Enter purchase date (mm/dd/yyyy): "); //prompts user to enter purchase date
scanf("%d/%d/%d", &month, &day, &year); //reads input date and stores it in month, day and year variables
float totalAmount = unitPrice * quantity; //computes the total amount
printf("\nItem\tUnit Price\tQTY\tPurchase Date\tTotal Amount\n"); //displays the item, unit price, qty, purchase data and total amount with tab space between each
printf("%d\t$%5.2f\t%d\t%.2d/%.2d/%d\t$%5.2f\n", itemNo, unitPrice,quantity, month, day, year,totalAmount); } //displays the values of itemNo, unitPrice, quantity, month, day, year and computed totalAmount with tab space between each
Explanation:
Lets suppose user enters 583 as item number, 13.5 as unit price, 2 as quantity and 09/15/2016 as date so
itemNo = 583
unitPrice = 13.5
quantity = 2
month = 09
day = 15
year = 2016
totalAmount is computed as:
totalAmount = unitPrice * quantity;
totalAmount = 13.5* 2
totalAmount = 27.00
Hence the output of the entire program is:
Item Unit Price QTY Purchase Date Total Amount
583 $ 13.50 2 09/15/2016 $ 27.00
The screenshot of the program along with its output is attached.
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class FunWithBranching { //class name
public static void main(String[] args) { //start of main function
Scanner input = new Scanner(System.in); //creates Scanner object
System.out.print("Enter your name: "); //prompts user to enter name
String userName = input.nextLine(); //stores the name
System.out.print("Welcome " + userName + "! Please answer the following questions:\n"); //prompts user to answer the questions
int randomOperand1 = (int)(20 * Math.random()) + 1; //generates random number for operand 1 (1-20)
int randomOperand2 = (int)(20 * Math.random()) + 1; //generates random number for operand 2 (1-20)
int randomAdd = randomOperand1 + randomOperand2; //performs addition of two random numbers and stores result in randomAdd
int randomMul = randomOperand1 * randomOperand2; //performs multiplication of two random numbers
int randomDiv = randomOperand1 / randomOperand2; //performs division of two random numbers
int randomMod = randomOperand1 % randomOperand2; //performs modulo of two random numbers
int correctAns = 0; //stores number of correct answers
System.out.print(randomOperand1 + " + " + randomOperand2 + " = "); //displays random number + random number
int AdditionGuess = input.nextInt(); //reads the answer of addition from user and stores it in AdditionGuess
if (AdditionGuess == randomOperand1 + randomOperand2) { //if the user answer is correct
System.out.println("Correct!"); //displays correct
correctAns++; //adds 1 to the count of correctAns every time the user gives correct answer of addition
} else { //if user answer is incorrect
System.out.println("Wrong!"); //displays wrong
System.out.println("The correct answer is " + randomAdd); } //displays the correct answer of addition
System.out.print(randomOperand1 + " * " + randomOperand2 + " = "); //displays random number * random number
int MultiplicationGuess = input.nextInt(); //reads the answer of multiplication from user and stores it in MultiplicationGuess
if (MultiplicationGuess == randomOperand1 * randomOperand2) { //if the user answer is correct
System.out.println("Correct!"); //displays correct
correctAns++; //adds 1 to the count of correctAns every time the user gives correct answer of multiplication
}else{ //if user answer is incorrect
System.out.println("Wrong!"); //displays wrong
System.out.println("The correct answer is " + randomMul); } //displays the correct answer of multiplication
System.out.print(randomOperand1 + " / " + randomOperand2 + " = "); //displays random number / random number
int DivisionGuess = input.nextInt(); //reads the answer of division from user and stores it in DivisionGuess
if (DivisionGuess == randomOperand1 / randomOperand2) { //if the user answer is correct
System.out.println("Correct!"); //displays correct
correctAns++; //adds 1 to the count of correctAns every time the user gives correct answer of division
}else{ //if user answer is incorrect
System.out.println("Wrong!"); //displays wrong
System.out.println("The correct answer is " + randomDiv); } //displays the correct answer of division
System.out.print(randomOperand1 + " % " + randomOperand2 + " = "); //displays random number % random number
int ModGuess = input.nextInt(); //reads the answer of modulo from user and stores it in ModGuess
if (ModGuess == randomOperand1 % randomOperand2) { //if the user answer is correct
System.out.println("Correct!"); //displays correct
correctAns++; //adds 1 to the count of correctAns every time the user gives correct answer of modulo
}else{ //if user answer is incorrect
System.out.println("Wrong!"); //displays wrong
System.out.println("The correct answer is " + randomMod); } //displays the correct answer of modulo
double percentage = correctAns * 25; //computes percentage
System.out.println("You got " + correctAns + " correct answers."); //display number of correct answers given by user
System.out.println("That's " + percentage + "%!"); } } //displays percentage
Explanation:
The program is well explained in the comments mentioned with each line of code. The screenshot of the output is attached.
