C++ Developer - Logical Operators

The video tutorial covers the basics of variables and data types in C, focusing on relational and logical operators. It explains the use of logical operators like AND, OR, and NOT, and their corresponding truth tables. The tutorial also classifies operators based on the number of operands they take, introducing binary, unary, and ternary operators. A practical coding example in C demonstrates the application of these logical operators, encouraging students to experiment with different boolean values.

Which of the following is NOT a common data type in C?

• INT

• FLOAT

• STRING

• BOOLEAN

What is the primary purpose of relational operators?

• To manage memory allocation

• To compare two values and return a boolean

• To perform arithmetic operations

• To manipulate strings

Which logical operator returns true only if both operands are true?

• Logical NOT

• Logical OR

• Logical AND

• Logical XOR

What is the result of the logical OR operation if both operands are false?

• True

• False

• Undefined

• Error

How many operands does a unary operator take?

• Two

• One

• Three

• Four

Which operator is used to reverse the truth value of its operand?

• Logical AND

• Logical OR

• Logical NOT

• Logical XOR

In the C program demonstration, what is the initial value of 'is raining'?

• Null

• Undefined

• False

• True

What does the 'Bool Alpha' manipulator do in the C program?

• Formats output as hexadecimal

• Inverts boolean values

• Displays boolean values as true/false

• Converts boolean values to integers

What is the expected output when both 'is raining' and 'is warm' are set to false?

• True for AND, False for OR, False for NOT

• False for AND, False for OR, True for NOT

• False for AND, True for OR, True for NOT

• True for AND, True for OR, False for NOT

What is the purpose of the challenge at the end of the video?

• To practice debugging skills

• To learn about new data types

• To test different permutations of boolean values

• To memorize the syntax of C
