C Language Data Types

What are the basic data types in C language?

• int, char, float, double, void

• long

• string

• bool

• short

What is the purpose of the sizeof operator in C?

• To control program flow

• To check for memory leaks

• To convert data types

• To determine the size of a variable or data type in bytes.

What is the size of 'int' data type in C language?

• 16 bytes

• 8 bytes

• 2 bytes

• 4 bytes

How is the size of a data type determined using the sizeof operator?

• The size of a data type is determined by the number of bits it occupies in memory

• The size of a data type is determined by the data type itself

• The size of a data type is determined by counting the number of characters it contains

• The size of a data type is determined by using the sizeof operator to calculate the number of bytes it occupies in memory.

What is the size of 'char' data type in C language?

• 1 byte

• 8 bytes

• 4 bytes

• 2 bytes

Explain the difference between 'int' and 'float' data types in C.

• Both 'int' and 'float' are used for integers in C.

• 'int' and 'float' are interchangeable data types in C.

• In C, 'int' is for floating-point numbers, while 'float' is for integers.

• In C, 'int' is for integers, while 'float' is for floating-point numbers.

How is the size of a structure calculated in C using the sizeof operator?

• sizeof(structure)

• sizeof(structure)

• sizeof(structure_name)

• sizeof(structure_name)

What is the size of 'double' data type in C language?

• 12 bytes

• 16 bytes

• 8 bytes

• 4 bytes

Why is it important to understand data types in C programming?

• It is important to understand data types in C programming to ensure proper memory allocation, manipulation, and interpretation of data.

• Manipulation of data in C programming does not require knowledge of data types

• Data types in C programming have no impact on memory allocation

• Understanding data types in C programming is not important

What is the significance of the 'long' keyword in C data types?

• It is used to declare constant variables.

• It is used to specify variables that can hold smaller values than 'int'.

• It is used to specify variables that can hold larger values than 'int'.

• It is used to define floating-point variables.
