contiguous memory allocation program in c
What is contiguous memory allocation with example?
Contiguous memory allocation refers to a memory management technique in which whenever there occurs a request by a user process for the memory, one of the sections of the contiguous memory block would be given to that process, in accordance with its requirement.
How to allocate contiguous memory in C?
C calloc() method
“calloc” or “contiguous allocation” method in C is used to dynamically allocate the specified number of blocks of memory of the specified type. it is very much similar to malloc() but has two different points and these are: It initializes each block with a default value '0'.Malloc gives only base address of allocated memory , because it allocates the memory in contiguous fashion so we can access further blocks of memory by simply incrementing the base address.
What is stored in contiguous memory?
The simplest file organization technique is contiguous storage.
Contiguous storage places blocks of records that are logically adjacent to one another into physically adjacent sectors.
