,Suppose that x is an int variable. Which of the following expressions always evaluates
to true?
Select one:
(x > 0) && ( x <= 0)
(x > 0) || ( x < 0)
(x > 0) || ( x <= 0)
( x == 5) && (x == 0) - Answer-(x > 0) || ( x <= 0)
Will the following display a "true" or a "false":
int x=10, y=15, z=20;
if ((x == 5) || (y != z))
cout << "true";
else
cout << "false";
T/F? - Answer-True
Which of the following would correctly test to see if the person in question is at least 21.
The person's age will be stored in the variable: age
if (age >= 21)
if (age < 21)
if (age > 21)
if (age <= 21)
if (age == 21) - Answer-if (age >= 21)
int x = -15;
if (!(x>0))
cout << "true";
else

What's the difference between initializing a variable and assigning a value to a variable?
- Answer-Assigning is storing a value into the variable's memory location. Once you
assign a value, you can reassign another value at any time.
Initializing is simply assigning a value to a variable for the first time.
Declare an integer variable called ageOfStudent and initialize it to 16. - Answer-int
ageOfStudent = 16;
, Declare a doublevariable called tipRateandinitializeit to .20. - Answer-double tipRate =
.20;
Declare twostringvariables called firstName, and lastName, but do not initialize them to
anything - Answer-string firstName, lastName;
Given an integer variable called ageOfStudent (assume it is already set), write a
statement that will
display the value of ageOfStudent. - Answer-cout << ageOfStudent;
Given a double variable called tipRate (assume it is already set to .20), write a
statement that will
display the value of tipRate with two decimal places. - Answer-cout << fixed <<
setprecision(2) << tipRate;
Given two string variables called firstName and lastName (assume they are both
already
initialized), write a statement that will display the values of firstName followed by a
space, followed
by the lastName - Answer-cout << firstName << " " << lastName << endl;
Given two string variables called firstName and lastName (assume they are both
already
initialized), write a statement that will display the values of lastName in a field of 20
spaces (rightjustified), followed by the value of firstName in a field of 20 spaces, also
right-justified). - Answer-cout << setw(20) << lastName << setw(20) << firstName;
Assume that m is an int variable that has already been given a value. Write a statement
that prints
out the value of m in a field of 10 positions. - Answer-cout << setw(10) << m;
Given two integer variables distance and speed, write an expression that
divides distance by speed using floating point arithmetic. - Answer-(double)
distance/speed
Assume that students is an integer variable containing the number of students in a
school, and
that teachers is an integer variable containing the number of teachers in the same
school. Write a
statement that will print out the average number of students per teacher.
Keep in mind that we want the answer to have a decimal number.
Hint: You will need to use type-casting. You may use the long or short version of type
casting - Answer-cout << (double) students/teachers;
. Given an int variable datum that has already been declared, write a statement that
reads an integer
