What is the difference between malloc and calloc?

Can you explain the difference between malloc and calloc in C?

Sure! malloc allocates a specified number of bytes and returns a pointer to the first byte. It does not initialize the memory.

What about calloc?

calloc allocates memory for an array of elements, initializes all bytes to zero, and returns a pointer to the memory.

So, malloc doesn't initialize memory, while calloc does?

Exactly! That's the main difference. malloc is faster since it doesn't initialize, while calloc ensures the memory is zeroed.

When should I use one over the other?

Use malloc when you don't need initialized memory and calloc when you need zero-initialized memory, like for arrays.
