-Write C++ statements that include the header files iostream and string.

-Write a C++ statement that allows you to use cin, cout, and endl without the prefix std::.

-Write C++ statements that declare and initialize the following named constants: SECRET of type int initialized to 11 and RATE of type double initialized to 12.50.

-Write C++ statements that declare the following variables: num1, num2, and newNum of type int; name of type string; and hoursWorked and wages of type double.

-Write C++ statements that prompt the user to input two integers and store the first number in num1 and the second number in num2.

-Write a C++ statement(s) that outputs the values of num1 and num2, indicating which is num1 and which is num2. For example, if num1 is 8 and num2 is 5, then the output is:

- Write a C++ statement that multiplies the value of num1 by 2, adds the value of num2 to it, and then stores the result in newNum.

Write a C++ statement that outputs the value of newNum. Write a C++ statement that updates the value of newNum by adding the value of the named constant SECRET to it.

Write a C++ statement that outputs the value of newNum with an appropriate message. Write C++ statements that prompt the user to enter a person’s last name and then store the last name into the variable name

Write C++ statements that prompt the user to enter a decimal number between 0 and 70 and then store the number entered into hoursWorked.

Write a C++ statement that multiplies the value of the named constant RATE with the value of hoursWorked and then stores the result into the variable wages.

Write C++ statements that produce the following output:

Name: //output the value of the variable name Pay Rate: $ //output the value of the RATE Hours Worked: //output the value of the variable //hoursWorked Salary: $ //output the value of the variable //wages For example, if the value of name is Rainbow and hoursWorked is 45.50, then the output is: Name: Rainbow Pay Rate: $12.50 Hours Worked: 45.50 Salary: $568.75

Explanation / Answer

a)

#include <iostream>

b)

using namespace std;

cout << "Enter a number: "<< endl;

cin >> n;

c)

int SECRET = 11;

double RATE = 12.50;

d)

int num1,num2,newNum;

string name;

double hoursWorked

e)

cout << "Enter two integersn";

cin >> num1 >> num2;

f)

cout << "First number you entered is " << num1 << ", Second number is "<< num2 << endl;

g)

newNum = (num1*2)+num2;

h)

cout << "the new number is " << newNum << endl;

i)

newNum+=SECRET;

j)

cout << "After adding secret value to it :" << endl;

k)

cout << "Enter persons last name :" << endl;

cin >> name;

l)

cout << "Enter a number between 0 to 70 :" << endl;

cin >> hoursWorked;

m)

wages = RATE * hoursWorked;

n)

cout << name << " PayRate :$" << RATE << " Hours Worked: " << setPrecision(2) << hourseWorked << " Salary :$" << wages << endl;
