1. Write a program that prompts the user to input a decimal number and outputs the number rounded to the nearest integer.

2. Consider the following program segment:
//include statement(s)
//using namespace statement
int main()
{
//variable declaration
//executable statements
//return statement
}

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

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

c. 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.

d. 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.

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

f. 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:
The value of num1 = 8 and the value of num2 = 5.

g. 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. Then, write a C++ statement that outputs the value of newNum.

h. Write a C++ statement that updates the value of newNum by adding the value of the named constant SECRET. Then, write a C++ statement that outputs the value of newNum with an appropriate message.

i. Write C++ statements that prompt the user to enter a person's last name and then store the last name into the variable name.

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

k. 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.

l. Write C++ statements that produce the following output:
Name: //output the value of the variable name
Pay Rate: $ //output the value of the variable 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

m. Write a C++ program that tests each of the C++ statements that you wrote in parts a through l. Place the statements at the appropriate place in the previous C++ program segment. Test run your program (twice) on the following input data:
a. num1 = 13, num2 = 28; name = "Jacobson"; hoursWorked = 48.30.
b. num1 = 32, num2 = 15; name = "Crawford"; hoursWorked = 58.45.
