What are some alternatives to malloc in C?

There are several alternatives to malloc in C, such as calloc, realloc, and using stack allocation. Would you like to know more about any specific one?

Can you explain how calloc differs from malloc?

Sure! calloc allocates memory for an array of elements and initializes all bytes to zero, while malloc just allocates memory without initialization.

What about realloc? How does it work?

realloc is used to resize a previously allocated memory block. It can increase or decrease the size and can also move the block to a new location if necessary.

Are there any performance considerations when using these alternatives?

Yes, performance can vary. For example, calloc may be slower due to initialization, while realloc can be more efficient if it doesn't need to move memory.
