Learn and Master C Programming - Introduction to C Data Types and Basic Types

This video tutorial provides an in-depth look at the basic data types in C programming, including character, integer, short, long, float, double, and long double types. It explains how to use the printf function and format specifiers to display these types and discusses the impact of signed and unsigned modifiers. The tutorial also covers the size of these data types in memory and demonstrates practical examples using Visual Studio.

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

• Character

• Floating-point

• Pointer

• Integer

What is the size of a char data type in C?

• 1 byte

• 2 bytes

• 4 bytes

• 8 bytes

How does the size of a signed char compare to an unsigned char in C?

• Unsigned char is larger

• Size depends on the compiler

• Signed char is larger

• They are the same size

What is the size of an integer data type in C on a 32-bit system?

• 8 bytes

• 4 bytes

• 2 bytes

• 1 byte

Which modifier can be used with integer types to allow larger values?

• Short

• Long

• Float

• Double

What is the size of a float data type in C?

• 1 byte

• 2 bytes

• 4 bytes

• 8 bytes

How does the size of a double compare to a float in C?

• Size depends on the system

• Double is larger

• Double is smaller

• Double is the same size

What is the size of a long double on a Windows platform?

• 12 bytes

• 16 bytes

• 8 bytes

• 4 bytes

Does compiling for 64-bit systems change the size of basic data types in C?

• Only floating-point sizes change

• Only integer sizes change

• No, sizes remain the same

• Yes, all sizes change

Which of the following statements is true about signed and unsigned integers in C?

• Unsigned integers are always smaller

• Unsigned integers can store larger values

• Both store the same range of values

• Signed integers can store larger values
