Operators are foundational in any programming language, and C++ is no exception. They perform various operations on variables and values. Let’s test your knowledge of C++ operators with this beginner-friendly quiz!
1. Which of the following is the assignment operator in C++?
Answer:
Explanation:
The = operator is used for assignment in C++. It assigns the value on its right to the variable on its left.
2. Which operator is used for checking equality?
Answer:
Explanation:
The == operator checks if the values of two operands are equal or not.
3. What is the result of 5 % 2?
Answer:
Explanation:
The % operator calculates the remainder of the division. 5 divided by 2 has a remainder of 1.
4. Which operator increases the value of a variable by 1?
Answer:
Explanation:
The ++ operator is the increment operator. It increases the value of a variable by 1.
5. What is the purpose of the != operator?
Answer:
Explanation:
The != operator checks if two operands are not equal.
6. What does the && operator represent?
Answer:
Explanation:
The && operator is the logical AND operator. It returns true if both operands are true.
7. Which operator has the highest precedence?
Answer:
Explanation:
Parentheses () have the highest precedence in C++. Expressions inside them are evaluated first.
8. What is the result of 10 | 5?
Answer:
Explanation:
The | operator is a bitwise OR operator. In binary, 10 is 1010 and 5 is 0101. The OR operation results in 1111 which is 15 in decimal.
9. Which operator is used to allocate dynamic memory in C++?
Answer:
Explanation:
The new operator is used in C++ to allocate dynamic memory on the heap.
10. What does the ^ operator do in C++?
Answer:
Explanation:
In C++, the ^ operator is the bitwise XOR operator. It returns 1 for differing bits and 0 for identical bits.
Congratulations on completing the quiz! Understanding operators is key to mastering C++ programming. If you found this quiz challenging, consider revisiting the topic and practicing with hands-on examples. Happy coding!
