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

• 16 bytes

• 1 byte

• 8 bytes

• 2 bytes or 4 bytes

What is the range of 'char' data type in Embedded C?

• 0 to 256

• -100 to 100

• -128 to 127 or 0 to 255

• -1 to 1

What is the difference between 'signed' and 'unsigned' data types in Embedded C?

• The 'signed' data type can only hold positive numbers, while the 'unsigned' data type can hold both positive and negative numbers.

• The 'signed' data type can only hold negative numbers, while the 'unsigned' data type can hold both positive and negative numbers.

• The 'signed' data type can only hold positive numbers, while the 'unsigned' data type can only hold negative numbers.

• The 'signed' data type can hold both positive and negative numbers, while the 'unsigned' data type can only hold positive numbers.

What is the purpose of 'if-else' statement in Embedded C?

• To declare a variable

• To repeat a certain block of code

• To make decisions based on certain conditions

• To print a message on the screen

How is a 'for' loop different from a 'while' loop in Embedded C?

• A 'for' loop is used when the number of iterations is known, while a 'while' loop is used when the number of iterations is not known in advance.

• A 'for' loop is used when the number of iterations is not known, while a 'while' loop is used when the number of iterations is known in advance.

• A 'for' loop can only be used with integers, while a 'while' loop can be used with any data type.

• A 'for' loop and a 'while' loop are the same in Embedded C.

Explain the use of 'switch' statement in Embedded C with an example.

• The 'switch' statement in Embedded C is used to repeat a block of code until a certain condition is met.

• The 'switch' statement in Embedded C is used to define a new variable within a function.

• The 'switch' statement in Embedded C is used to perform arithmetic operations on two variables.

• The 'switch' statement in Embedded C is used to select one of many code blocks to be executed based on the value of an expression.

What is the significance of pointers in Embedded C?

• They are used for high-level data manipulation

• They allow direct access to memory and hardware registers

• They are only used for debugging purposes

• They are not relevant in Embedded C programming

How are pointers used to pass arguments to functions in Embedded C?

• By passing the variable itself

• By passing the value of the variable

• By passing the function name

• By passing the memory address of the variable

Explain the concept of function pointers in Embedded C.

• Function pointers in Embedded C are pointers that point to functions instead of data. They are used to call functions indirectly through the pointer.

• Function pointers in Embedded C are not supported by the language

• Function pointers in Embedded C are only used for data manipulation

• Function pointers in Embedded C are used to store integer values

How are interrupts handled in Embedded C?

• By using interrupt service routines (ISRs)

• By using object-oriented programming

• By using machine learning algorithms

• By using blockchain technology
