C++ for Beginners - Simple Data Type: int

This video tutorial covers the basics of integers, including signed and unsigned types, their limits, and how they are stored. It explains how to declare integers using the INT keyword and perform mathematical operations on them. The tutorial also discusses the importance of understanding integer limits and introduces the C limits library to determine these limits. The video concludes with a summary of the key concepts discussed.

What is the primary difference between signed and unsigned integers?

• Signed integers can only be positive.

• Unsigned integers can be negative.

• Signed integers can be both positive and negative.

• Unsigned integers can store fractional values.

What happens when you assign a negative value to an unsigned integer?

• It stores a large positive value instead.

• It results in a compilation error.

• It converts the negative value to zero.

• It stores the negative value as is.

Which keyword is used to explicitly declare an integer that can be negative or positive?

• float

• signed

• int

• unsigned

What is the result of dividing an integer by a number that does not evenly divide it?

• The result is stored as a fraction.

• The result is rounded up to the nearest whole number.

• The result is rounded down to the nearest whole number.

• The result is a floating-point number.

Why can't integers store infinite values?

• Because they can only store positive values.

• Because they are only used for small numbers.

• Because they are limited by the storage space available.

• Because they are always signed.

What constant represents the maximum value a signed integer can hold?

• UINT_MIN

• INT_MIN

• INT_MAX

• UINT_MAX

Why is there no constant for the minimum value of an unsigned integer?

• Because the minimum value is always zero.

• Because it is not needed in programming.

• Because unsigned integers can be negative.

• Because it is the same as the maximum value.
