Output

The code you've provided is already in C, which is a platform-independent language. This means that it can run on any platform that has a C compiler, including Ubuntu. However, the code does use some libraries that are specific to Apple's platforms, such as `<CommonCrypto/CommonDigest.h>`. To make this code run on Ubuntu, we'll need to replace these libraries with equivalent functions from a library that's available on Ubuntu. In this case, we can use the OpenSSL library, which provides similar functionality and is available on Ubuntu. Here's how you can modify the code:

To compile and run this code on Ubuntu, you'll need to install the OpenSSL development libraries if they're not already installed. You can do this with the following command: 
1
sudo apt-get install libssl-dev
Then, you can compile the code with gcc like this: 
1
gcc -o my_program my_program.c -lcrypto
And run it like this: 
1
./my_program arg1 arg2

The code you've provided is already in C, which is a platform-independent language. This means that it can run on any platform that has a C compiler, including Ubuntu. However, the code does use some platform-specific libraries, such as `<CommonCrypto/CommonDigest.h>`, which is specific to macOS and iOS. To make this code run on Ubuntu, you would need to replace the platform-specific libraries with equivalent libraries that are available on Ubuntu. For MD5 hashing, which is what `<CommonCrypto/CommonDigest.h>` is used for in this code, you can use the `<openssl/md5.h>` library instead. Here's how you can modify the code:

Please note that you'll need to have OpenSSL installed on your Ubuntu system to compile and run this code. You can install it using the following command: 
1
sudo apt-get install libssl-dev
You can then compile the code using gcc: 
1
gcc -o outputfile sourcefile.c -lssl -lcrypto

Output

The code you've provided is already compatible with Ubuntu, as it's written in standard C and uses libraries that are available on Ubuntu. However, the `CommonCrypto/CommonDigest.h` library is specific to Apple's platforms, so we'll need to replace it with a library that provides similar functionality and is available on Ubuntu. The `openssl` library is a good choice for this. Here's your code modified to use `openssl`:

To compile and run this code on Ubuntu, you'll need to install the `openssl` development package: 
1
sudo apt-get install libssl-dev
Then, you can compile the code with `gcc`: 
1
gcc -o my_program my_program.c -lcrypto
And run it: 
1
./my_program

Output

The code you've provided is already in C, which is a platform-independent language. This means that it can run on any platform that has a C compiler, including Ubuntu. However, the code does use some platform-specific libraries, such as `<CommonCrypto/CommonDigest.h>`, which is specific to Apple's platforms. To make this code run on Ubuntu, you'll need to replace the Apple-specific libraries with libraries that provide similar functionality and are available on Ubuntu. For MD5 hashing, a common cross-platform library is OpenSSL. Here's how you might modify the code:

To compile this code on Ubuntu, you'll need to install the OpenSSL development libraries if they're not already installed. You can do this with the following command: 
1
sudo apt-get install libssl-dev
Then, you can compile the code with gcc: 
1
gcc -o my_program my_program.c -lssl -lcrypto
This will produce an executable named `my_program` that you can run.

Output

The given C code is already compatible with Ubuntu, as it uses standard C libraries and does not contain any platform-specific code. However, the `CommonCrypto/CommonDigest.h` header is specific to Apple's platforms, so you'll need to replace it with a different MD5 implementation for the code to compile on Ubuntu. Here's the modified code using the `openssl/md5.h` library:

}
To compile the modified code, you will need to install the OpenSSL development package on Ubuntu: 
1
2
sudo apt-get update
sudo apt-get install libssl-dev
After installing the package, compile the code using: 
1
gcc -o my_program my_program.c -lssl -lcrypto
This will create an executable named "my_program" that you can run on Ubuntu.
