Creating a Question

To create a new question for the cracking-cpp collection, follow these steps:

1. Create a folder for the question:

   • Name the folder appropriately, using a descriptive and concise title for the question.
   • Place the folder in the appropriate location within the project structure.

2. Create a CMake file for the question:

   • Name the CMake file according to the question's folder name.
   • Include any necessary build instructions or dependencies in the CMake file.

3. Add the question folder to the main CMake file:

   • Open the main CMake file located in the root directory of the project.
   • Add a reference to the question's folder in the appropriate section of the CMake file.

By following these steps, you can easily create a new question and integrate it into the cracking-cpp project.

Building and Running the Questions

To build and run the questions in the cracking-cpp collection, follow these steps:

1. Create a build directory:

   • Open a terminal and navigate to the root directory of the project.
   • Execute the following commands:
     • mkdir build
     • cd build

2. Generate the build files using CMake:

   • Execute the following command:
     • cmake ..

3. Build the project using the generated build files:

   • Execute the following command:
     • make (to build all questions) or make sample_question (to build a specific question)

4. Run the executable:

   • Execute the following command:
     • ./sample_question/sample_question (replace sample_question with the appropriate question name)

By following these steps, you can successfully build and run the questions in the cracking-cpp project.

Building, Testing, and Cleaning the Questions Using a Script

To simplify the process of building, testing, and cleaning the questions in the cracking-cpp collection, a script called build.sh is provided. Here is how you can use the script:

$ ./build.sh -h

The script supports the following options:

• -h: Print the help message.

You can use the script with the following commands:

• build: Build all questions.
• test: Run tests for all questions.
• clean: Clean build files.

Additionally, you can specify a question using the -q option. By default, the script will perform the specified command for all questions. To specify a specific question, provide the name of the question after the -q option.

By using the build.sh script, you can easily build, test, and clean the questions in the cracking-cpp project.
