How can I use free in C programming?
An example of an AI chatbot conversation about using the free function in C programming.
What does the free function do in C?
The free function in C is used to deallocate memory that was previously allocated using malloc, calloc, or realloc.
When should I use free in my code?
You should use free when you no longer need the dynamically allocated memory to prevent memory leaks.
Can you show me an example of using free?
Sure! Here's a simple example:
int *arr = malloc(10 * sizeof(int));
// Use the array...
free(arr); // Deallocate memory
What happens if I forget to use free?
Forgetting to use free can lead to memory leaks, which can cause your program to consume more memory over time.
