Understanding and working with Memset in C

memset is a memory utility in C which is used to set a particular value to a range of memory locations in an efficient way. On going through this article, you will understand How to use memset? and Why performance of memset is better than a simple implementation?

C++

delete operator in C++

In C++, Delete is an operator that is used to destroy array and non-array(pointer) objects which are created by new operator as well as NULL pointers. Using operator overloading, we can delete user defined objects as well

C++

new operator in C++

In C++, the new operator denotes a request for memory allocation on the Heap. If sufficient memory is available, new operator initializes the memory and returns the address of the newly allocated and initialized memory to the pointer variable.

Dynamic memory allocation in C

The process of allocating memory at run time is known as dynamic memory allocation. Although C does not inherently have this facility, there are four library routines that can be used for allocating and freeing memory during program execution: malloc, calloc, realloc and free

malloc vs calloc vs realloc

We take a deep look into the 3 dynamic memory allocation techniques in C/ C++ namely malloc, calloc and realloc and explore the difference. malloc stand for memory allocations, calloc for contiguous allocation and realloc for re-allocation.
