The Source Codes

TYPE_DATA*** dbShares = new TYPE_DATA**[NUM_SERVERS];
    for (TYPE_SIZE i = 0; i < NUM_SERVERS; i++) {
        dbShares[i] = new TYPE_DATA*[BUCKET_SIZE];
        for (TYPE_SIZE j = 0; j < BUCKET_SIZE; j++) {
            dbShares[i][j] = new TYPE_DATA[this->totalNumBlocks];
        }
    }

The Corresponding free ways

To free the memory allocated for dbShares in the given code, you need to deallocate the memory in the reverse order of allocation. The deallocation can be done using the delete[] operator. Here’s how you can do it:

// Free the memory for dbShares
for (TYPE_SIZE i = 0; i < NUM_SERVERS; i++) {
    for (TYPE_SIZE j = 0; j < BUCKET_SIZE; j++) {
        delete[] dbShares[i][j]; // Free the memory for each TYPE_DATA array
    }
    delete[] dbShares[i]; // Free the memory for each TYPE_DATA* array
}
delete[] dbShares; // Free the memory for the TYPE_DATA** array

Make sure you add this code where it’s appropriate to free the memory, such as when you’re done using dbShares, or inside the destructor of the class (if dbShares is a member of a class). This will help you prevent memory leaks in your program.

How to check the current memory usage for ubuntu? (Recommend the Third one)

You can check the current memory usage on Ubuntu using the following commands:

• free -m: This command will show you the available memory and how the memory has been allocated in Megabytes. ^{1 2}
• top: This command is used to print CPU and memory usage of your system. ³
• htop: This command also gives a detailed analysis of your CPU and memory usage. ³

I hope this helps! Let me know if you have any other questions.
