Answer:

Here are the two statements which use nextInt() to print two random integers between 0 and 9:

System.out.println(randGen.nextInt(10));

System.out.println(randGen.nextInt(10));

Explanation:

Here is the complete program:

import java.util.Scanner;   //to accept input from user

import java.util.Random;   // use to generate random numbers

public class DiceRoll {  //class definition

public static void main (String [] args)  {//start of main function  

Random randGen = new Random();   // creates a Random class object randGen

int seedVal = 0;   //sets starting point for generating random numbers

randGen.setSeed(seedVal);   //sets the seed of random number generator

System.out.println(randGen.nextInt(10));  //generates and prints the first random integer between 0 and 9 (10 is the range from 0 to 9) using nextInt method, which is used to get next random integer value from the sequence of random number generator

System.out.println(randGen.nextInt(10));   //generates and prints the second random integer between 0 and 9 (10 is the range from 0 to 9) using nextInt method

return;    }  }

Another way to write this is to initialize two int variables:

int integer1;

int integer2;

Now use two print statements to print these random integers between 0 and 9 as:

System.out.println(integer1= randGen.nextInt(10));

System.out.println(integer1= randGen.nextInt(10));

Another way to write this is:

Set the value of integer1 to a random number from 0 to 9 and same for integer2

int  integer1 = randGen.nextInt(10);

int  integer2 = randGen.nextInt(10);  

Now use two print statements to print these random integers between 0 and 9 as:  

System.out.println(integer1);

System.out.println(integer2);

You and a few friends are having a meal at a pizza restaurant, and the server has just given you the bill. Write a function that
cestrela7 [59]

Answer:

How to calculate the total cost of the meal

For bill inclusive of tax, cost1=cost*(1+tax percentage)

For bill inclusive of tax and tip, cost2=cost1*(1+tip percentage)

Meal cost =(pizza cost*(1+tax percentage))*(1+tip percentage)

Now how to calculate the cost per person

cost per person=meal cost/ number of people.

C language code to solve the above problem is given below with appropriate comments for explanation

Explanation:

#include<stdio.h>

float split_bill(int cost,float tax)

{

//Declaring number of people as int

int number;

//Prompting for number of people

printf("Enter number of people ");

scanf("%d",&number);

//Declaring tip percentage as float

float tip_percent;

//Prompting for tip percentage

printf("Enter tip percentage between 0 and 1 ");

scanf("%f",&tip_percent);

//Calculating total meal cost

float meal=(((float)cost)*(1+tax))*(1+tip_percent);

//Printing total cost of meal

printf("Total cost of meal: %0.2f ",meal);

//Calculating cost per person

float cost_per_person=meal/number;

//Returning cost per person to main function

return cost_per_person;

}

int main()

{

//Declaring pizza cost as int and tax percentage as float

int pizza_cost;

float tax_percent;

//Prompting user for pizza cost

printf("Enter billing amount of pizza ");

scanf("%d",&pizza_cost);

//Prompting user for tax percentage

printf("Enter tax percentage between 0 and 1 ");

scanf("%f",&tax_percent);

//Printing the cost per person by calling the function split_bill

printf("Total cost per person is: %0.2f ",split_bill(pizza_cost,tax_percent));

return 0;

}
