malloc vs calloc - Dynamic Allocation
Learn the differences between malloc and calloc for dynamic memory allocation in C.
malloc vs calloc
Both allocate memory on the heap, but they differ in initialization.
malloc
malloc(size)allocatessizebytes- Contents are uninitialized (garbage values)
- Use when you will immediately overwrite the memory
calloc
calloc(count, size)allocatescount * sizebytes- Contents are zero-initialized
- Use when you need a clean slate (e.g., arrays of zeros)
