The malloc() (memory allocation) function dynamically allocates a block of memory of a specified size in bytes. The allocated memory is uninitialized, meaning it may contain arbitrary data (often referred to as garbage values). If the allocation is successful, malloc() returns a pointer to the...

the new block can be in a different location. Because the new block can be in a new memory location, the pointer returned by realloc is not guaranteed to be the pointer passed through the memblock argument.realloc calls malloc in order to use the C++ _set_new_mode function to...
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 used malloc() function, calloc() function, realloc() function, and free() function.← Prev Next → ...
