### Explanation: 1. **CRC32 Table Initialization**: The `init_crc32_table` function initializes a table of CRC32 values for each possible byte (0-255) using the polynomial for CRC32 (`0xedb88320`). 2. **CRC32 Calculation**: The `crc32` function takes a string and its length as input. It processes each byte of the string, updating the CRC value according to the CRC32 algorithm. 3. **Main Function**: In `main`, we define the input string "correct horse battery staple", initialize the CRC32 table, calculate the CRC32 hash, and print the result in hexadecimal format. ### Compilation and Execution: To compile and run this program, save it to a file named `crc32.c`, then use the following commands in your terminal: 
1
2
gcc -o crc32 crc32.c
./crc32
This will output the CRC32 hash of the specified string.

### Explanation: 1. **CRC32 Polynomial**: We use the standard polynomial `0xEDB88320` which is widely used for CRC32 calculations. 2. **CRC32 Function**: - Initializes the CRC to `0xFFFFFFFF`. - Iterates through each byte of the input data, XORing it with the current CRC value. - For each bit in the byte, it shifts the CRC value and performs the polynomial reduction if the least significant bit is set. 3. **Main Function**: - The input string "correct horse battery staple" is defined. - The `crc32` function is called with the input string, and the result is printed in hexadecimal format. ### Compilation and Execution: To compile and run the program, you can use a C compiler such as `gcc`:

2
gcc -o crc32_calculator crc32_calculator.c
./crc32_calculator
This will output the CRC32 hash of the specified string.

### Explanation: 1. **CRC32 Table Initialization**: The `init_crc32_table` function computes and fills an array with precomputed CRC32 values for all 256 possible byte values. This speeds up the CRC calculation process. 2. **CRC32 Calculation**: The `crc32` function iterates over each byte of the input data, updating the CRC value based on the byte and the current CRC state, using the precomputed table. 3. **Main Function**: The `main` function defines the input string, initializes the CRC table, computes the CRC32 hash, and prints it in hexadecimal format. ### Compilation and Execution: To compile and run the program, you can use the following commands in your terminal: 
1
2
gcc -o crc32_calculator crc32_calculator.c
./crc32_calculator
This will output the CRC32 hash of the string "correct horse battery staple".

### Explanation: 1. **CRC32 Lookup Table Initialization**: The `init_crc32_table` function initializes a lookup table for CRC32 using the polynomial `0xedb88320`, which is commonly used for CRC32 calculations. 2. **CRC32 Calculation**: The `crc32` function computes the CRC32 value for the input string. It starts with an initial value of `0xffffffff` and processes each byte of the input string using the lookup table. 3. **Main Function**: The `main` function initializes the CRC32 table, computes the CRC32 for the specified string, and prints the result in hexadecimal format. ### Compilation: You can compile the program using `gcc`: 
1
gcc crc32.c -o crc32
### Running: After compiling, run the program: 
1
./crc32
This will output the CRC32 hash of the string "correct horse battery staple".

### Explanation: 1. **CRC32 Table Initialization**: The `init_crc32_table` function initializes a lookup table for the CRC32 algorithm. This table allows for quick calculations of the CRC32 value. 2. **CRC32 Calculation**: The `crc32` function computes the CRC32 hash for the given input data. It processes each byte of the input string and updates the CRC value based on the CRC32 table. 3. **Main Function**: In the `main` function, we define the input string and its length, initialize the CRC32 table, compute the CRC32 hash, and print the result in hexadecimal format. ### Compilation and Execution To compile and run this program, you can use the following commands in a terminal: 
1
2
gcc -o crc32_calculator crc32_calculator.c
./crc32_calculator
Make sure to save the code in a file named `crc32_calculator.c`. The output will display the CRC32 hash of the specified string.
