Program to find endianness and number of bits set in bit magic.

• Use bitwise operators to check endianness

• Count number of set bits using bitwise AND and right shift

• Use pre-defined functions for endianness in some programming languages

• Endianness can affect network communication and file formats

IPC stands for Inter-Process Communication and is used for communication between processes in an operating system.

• Shared memory

• Message passing

• Pipes

• Sockets

• Remote Procedure Calls (RPC)

• Semaphores

• Mutexes

To reverse a 32 byte number, swap the first and last byte, second and second last byte, and so on.

• Iterate through the first half of the number and swap each byte with its corresponding byte from the second half.

• Use bitwise operations to swap the bytes.

• Convert the number to a string, reverse the string, and convert it back to a number.

Macro is a preprocessor directive that performs text substitution. Storing 5 bits in a character can be done using bit manipulation. Dangling pointers are pointers that point to invalid memory locations. Inline functions are functions that are expanded by the compiler at the point of call.

• Macros are used to define constants or to perform text substitution

• To store 5 bits in a character, we can use bit manipulation opera...read more
