Complete Modern C++ - Primitive Types and Variables

This video tutorial covers the C type system, including arithmetic and special types, modifiers, and qualifiers. It explains memory requirements and range of types, and how to declare and initialize variables. The video also provides examples and best practices for using types in C programs, emphasizing the importance of initializing variables to avoid errors.

Which of the following is NOT an arithmetic type in C?

• Integral

• Boolean

• Floating point

• White

What is the purpose of the 'unsigned' modifier in C?

• To restrict to positive values

• To allow negative values

• To increase memory size

• To decrease memory size

How can you find the range of a type in C?

• By using the C limits header file

• By using the C float header file

• By using the C range header file

• By using the C memory header file

What happens if you try to read an uninitialized variable in C?

• It will return a junk value

• It will cause a compilation error

• It will automatically initialize to a default value

• It will always return zero

Which of the following is a correct way to declare an integer variable in C?

• i int;

• int i;

• integer i;

• var i;

What is the benefit of using uniform initialization in C-11?

• It allows for different syntax for scalar and vector types

• It simplifies initialization syntax using curly braces

• It requires the use of assignment operators

• It restricts initialization to scalar types only

Which of the following is a valid Boolean initialization in C?

• bool flag = 'false';

• bool flag = 0.0;

• bool flag = 'true';

• bool flag = 1;
