Appending Values to an Array

Appending values to an array is a fundamental operation in programming. In our library, you can use the CHashArray_append function to add new elements to the end of an array. Let's dive into how this works with a detailed example.

Example: Appending Strings to an Array

Here's a step-by-step guide on how to append values to an array:

1. Include the Necessary Header: Start by including the CHashManipulatorOne.c header file which contains the necessary definitions for our library.

   #include "CHashManipulatorOne.c"
   

2. Initialize the Namespace and Modules: We need to initialize the CHashNamespace and its modules like object, array, and validator.

   CHashNamespace hash = newCHashNamespace();
   CHashObjectModule obj = hash.object;
   CHashArrayModule array = hash.array;
   CHashValidatorModule validator = hash.validator;
   

3. Create an Array: Use the newCHashArray function to create an array with initial elements.

   CHashObject *create() {
       return newCHashArray(
           hash.newString("aaa"),
           hash.newNumber(26),
           hash.newNumber(20),
           hash.newBool(true)
       );
   }
   

4. Append New Elements: Use CHashArray_append to add new elements to the array. In this example, we're appending two strings.

   int main() {
       CHashArray *element = create();
   
       CHashArray_append(
           element,
           hash.newString("b"),
           hash.newString("c")
       );
   

5. Check for Errors: After appending, check if there were any errors during the operation.

       if (!hash.errors(element)) {
           hash.print(element);
       } else {
           printf("%s", hash.get_error_message(element));
       }
   

6. Free the Memory: Don't forget to free the memory allocated for the array to prevent memory leaks.

       hash.free(element);
   }
   

Full Code Example

Here's the complete code example that demonstrates how to append values to an array:

#include "CHashManipulatorOne.c"

CHashNamespace hash;
CHashObjectModule obj;
CHashArrayModule array;
CHashValidatorModule validator;

CHashObject *create() {
    return newCHashArray(
        hash.newString("aaa"),
        hash.newNumber(26),
        hash.newNumber(20),
        hash.newBool(true)
    );
}

int main() {
    hash = newCHashNamespace();
    obj = hash.object;
    array = hash.array;
    validator = hash.validator;
    CHashArray *element = create();

    CHashArray_append(
        element,
        hash.newString("b"),
        hash.newString("c")
    );

    if (!hash.errors(element)) {
        hash.print(element);
    } else {
        printf("%s", hash.get_error_message(element));
    }

    hash.free(element);
}

By following these steps, you can easily append values to an array using our library. Remember to always check for errors and manage memory properly to ensure your program runs smoothly.
