​LESSON 4: CONNECTING DATA THROUGH OPERATORS

TEST I-A - TRUE OR FALSE​

Choose the word  TRUE if the statement is true or FALSE if it is false.

Multiple Choice

All relational operators are unary operators.

• TRUE

• FALSE

Multiple Choice

The NOT (!) operator is a unary operator that negates/reverses the value of the operand.

• TRUE

• FALSE

Multiple Choice

The logical AND (&&) operator is a binary operator that returns true only when all operands are true

• TRUE

• FALSE

TEST I-B - TRUE OR FALSE​

Evaluate the following arithmetic expressions where x=2, y=4, z=6. Assume that the results of the operations in the previous questions will not affect the answers of the next questions. After evaluating the expression, choose the word  TRUE if the result of the expression is correct or FALSE if it is false.

Multiple Choice

b=++y;  

result: b=5

• TRUE

• FALSE

Multiple Choice

e=x*y;   

result: e=12

• TRUE

• FALSE

Multiple Choice

z+=20;  

result: z=20

• TRUE

• FALSE

TEST I-C - TRUE OR FALSE​

Evaluate the following logical expressions where a=true, b=false, c=true. After evaluating the expression, choose the word  TRUE if the result of the expression is true or FALSE if it is false

Multiple Choice

(b || c) && (a && c)

• TRUE

• FALSE

Multiple Choice

(!b ^ !a) || (c && a)

• TRUE

• FALSE

Multiple Choice

(a || b) ^ (b && c)

• TRUE

• FALSE

TEST I-D - TRUE OR FALSE​

Evaluate the following relational expressions where e=1, j=4, b= 3, m=3. After evaluating the expression, choose the word  TRUE if the result of the expression is true or FALSE if it is false.

Multiple Choice

j <= b

• TRUE

• FALSE

Multiple Choice

j != m

• TRUE

• FALSE

Multiple Choice

m >= e

• TRUE

• FALSE

TEST II - MULTIPLE CHOICE

For each item, you are given four choices from which you select the correct answer.

Multiple Choice

The NOT (!), AND (&&), and OR (||) belongs to what type of operators?

• Arithmetic Operators

• Logical Operators

• Relational Operators

• Shorthand Operators

Multiple Choice

What is the equivalent Java expression of the statement

“Assign to variable A the remainder when the value of variable B is divided by 15”?

• A = B / 15;

• A = B % 15;

• A ^ B / 15;

• A / B ^ 15;

Multiple Choice

Which of the following is the equivalent expression of Sum=Sum+99 if shorthand operator is used?

• Sum++=99;

• Sum*=99;

• Sum+=99;

• Sum%=99;
