Q1. What is difference between Normal OS and RTOS? What is difference between microcontroller and microprocessor? Write a C program to swap two numbers without using 3rd variable.
Ans. 
RTOS is a real-time operating system designed for time-sensitive applications. Microcontrollers are integrated circuits with built-in memory and peripherals.
• RTOS is designed to provide deterministic and predictable response times for critical tasks.

• Normal OS is designed for general-purpose computing and may not prioritize real-time tasks.

• Microcontrollers are typically used in embedded systems and have limited resources...read more

Q2. What is storage class in C?
Ans. 
Storage class in C determines the scope, visibility, and lifetime of variables.
• C has four storage classes: auto, register, static, and extern.

• Auto storage class is the default and is used for local variables.

• Register storage class is used for variables that should be stored in CPU registers for faster access.

• Static storage class is used for variables that retain their values between function calls.

• Extern storage class ...read more

Q3. What is difference between macro and constant variable in C? How to divide a number without using division operator?
Ans. 
A macro is a preprocessor directive that is replaced by its value before compilation, while a constant variable is a read-only variable.
• Macros are defined using the #define directive, while constant variables are declared using the const keyword.

• Macros are replaced by their values during preprocessing, while constant variables are stored in memory.

• Macros can lead to code duplication, while constant variables provide ty...read more
