## How do you reverse a bit in a byte?

Reverse by Rotation

1. As the length of an unsigner char is 1 byte, which is equal to 8 bits, it means we will scan each bit while (byte_len–)
2. We first check if b as a bit on the extreme right with (b & 1) ; if so we set bit 1 on r with | and move it just 1 bit to the left by multiplying r by 2 with (r << 1)

How do you reverse a bit in C++?

Reverse Bits in C++

1. Suppose n is the given number.
3. for i := 31 down to 0: answer := answer OR (n AND i), and shift it to the left i times. n := n after right shifting 1 bit.

### How do you reverse a hexadecimal number?

Efficient approach:

1. Move the position of the last byte to the first byte using left shift operator(<<).

### How do you reverse a string?

1. Input the string from the user.
2. Find the length of the string. The actual length of the string is one less than the number of characters in the string.

4. rev[i] = str[j]
5. Print the reversed string.

What is little-endian format?

Specifically, little-endian is when the least significant bytes are stored before the more significant bytes, and big-endian is when the most significant bytes are stored before the less significant bytes. When we write a number (in hex), i.e. 0x12345678 , we write it with the most significant byte first (the 12 part).

## Why is Little Endian better?

The advantages of Little Endian are: It’s easy to read the value in a variety of type sizes. For example, the variable A = 0x13 in 64-bit value in memory at the address B will be 1300 0000 0000 0000 . A will always be read as 19 regardless of using 8, 16, 32, 64-bit reads.

## Is x86_64 little endian?

Current architectures The Intel x86 and AMD64 / x86-64 series of processors use the little-endian format.

How do I know if my system is big endian?

NET: Check the value of BitConverter. IsLittleEndian . If the output starts with a 1 (least-significant byte), it’s a little-endian system. If the output starts with a higher digit (most-significant byte), it’s a big-endian system.
