In the C Programming Language, the malloc function allocates a block of memory for an array, but it does not clear the block. To allocate and clear the block, use the calloc function.SyntaxThe syntax for the malloc function in the C Language is:void...
Syntax ofmalloc: void*malloc(size_t size); Parameters: size: Specifies the number of bytes to allocate in memory. Return Type: void*: It returns a void pointer (void*) that can be implicitly cast to any other pointer type. This pointer points to the allocated memory block. ...
Our first example will be assigning a memory while returning a pointer in the C language. Open your Linux terminal by a shortcut key “Ctrl+Alt+T”. Create a new file “malloc.c” with a “touch” command in your shell and then open it within GNU editor. Now that the file has been...
In this way, we can make use of dynamic memory allocation in our program. So this was all about dynamic memory allocation in C language where we usedmalloc()function,calloc()function,realloc()function, andfree()function. ← Prev Next →...

One reason is to hide the somewhat awkward syntax, and another is that if you're writing a more complicated allocator you might wantconstructanddestroyto have some side effects beside object construction and destruction. An allocator might, for example, maintain a log of all currently active obje...
Since it is programmer’s responsibility to deallocate dynamically allocated memory, programmers are provided delete operator by C++ language. Syntax: // Release memory pointed by pointer-variabledeletepointer-variable; Here, pointer-variable is the pointer that points to the data object created bynew...
