free() - built in function to free or clear the memory space. If you use free, the referred memory location released for the future use or other operations.

Clears the memory, correct.
free(void * block)
Free is used to deallocate the memory allocated by malloc, calloc.

May I know then,
What is the difference between "free(var-name)" and "dalloc(var-name)"?

free(); is the key word in stdio.h library which free the allocated by the variable given as argument.

The heap is reason of free because of that our program can use memory via c's DYNAMIC ALLOCATION function.
But in delete() function asks the user to specify the index of the address that to be deleted.

We used the free () function to free dynamically allocated memory. Such as malloc () and alloc ().
And we use the delete for destroy an object.
Or another way we can say that for explicitly destroyed we used delet.

Its just free the memory for the current use.

Delete means increase space but at that deleted location take over by next allocated data. Hence that memory address is not free permanently.
While free means at that location space for another data entry. This location is not fill without user sent data by taking that reference.
