Quiz - 3 Assignment, Increment & Decrement Operators in C

What is the assignment operator in C?

• +

• =

• *

• /

How is the increment operator represented in C?

• ++

• --

• ==

• +=

What does the decrement operator do in C?

• Increases the value of a variable by 1

• Decreases the value of a variable by 1

• Assigns a new value to a variable

• Multiplies the value of a variable by 2

Give an example of using the assignment operator in C.

• x == 10;

• x = 10;

• x += 10;

• x := 10;

Explain the difference between pre-increment and post-increment operators in C.

• Pre-increment and post-increment are the same.

• Pre-increment returns first, then increments the value. Post-increment increments first, then returns the value.

• Pre-increment decrements first, then returns the value. Post-increment returns first, then increments the value.

• Pre-increment increments first, then returns the value. Post-increment returns first, then increments the value.

When should you use the decrement operator in C?

• When you want to increase the value of a variable by 1.

• When you want to multiply the value of a variable by 2.

• When you want to assign a new value to a variable.

• When you want to decrease the value of a variable by 1.

What happens if you use the assignment operator with different data types in C?

• The program crashes without any error message

• The value on the right side is implicitly converted to the data type on the left side, and if the conversion is not possible, a compilation error occurs.

• The data types are automatically converted to a common type

• The assignment is successful without any issues

Discuss the concept of compound assignment operators in C.

• Compound assignment operators in C are used for logical operations only.

• Compound assignment operators in C are shortcuts that combine an arithmetic or bitwise operation with an assignment.

• Compound assignment operators in C are only applicable to floating-point numbers.

• Compound assignment operators in C cannot be combined with assignment.

How does the increment operator affect the value of a variable in C?

• It has no effect on the value of the variable.

• It multiplies the value of the variable by 2.

• It increases the value of the variable by 1.

• It decreases the value of the variable by 1.

Can you combine increment and assignment operators in C? Provide an example.

• int x = 5; x += 2;

• int x = 5; x =- 2;

• int x = 5; x =+ 2;

• int x = 5; x =* 2;
