De-Allocate Memory Research Paper

Now, next task is de-allocation of memory. We will use free() function to de-allocate memory. Following statement will accomplish this task: free(data); It will de-allocate memory to reuse, but still ‘data’ pointer will points to that memory location. We can called ‘data’ pointer is a dangling pointer because it pointing to memory even it is de-allocated. Dangling pointer is a pointer which is pointing to nothing. To remove dangling pointer we use following statement: data =
