- Q6. What is the difference between into arr [5] and malloc (5*sizeof (int))
- Ans.
The difference is that 'int arr[5]' creates an array on the stack, while 'malloc(5*sizeof(int))' allocates memory on the heap.
int arr[5] creates an array of 5 integers on the stack, which is a fixed-size memory allocation.
malloc(5*sizeof(int)) dynamically allocates memory on the heap, allowing for variable-size memory allocation.
The memory allocated with malloc must be explicitly freed with free() to avoid memory leaks...
