The above statement allocates 400 bytes of memory. It's because the size offloatis 4 bytes. And, the pointerptrholds the address of the first byte in the allocated memory. The expression results in aNULLpointer if the memory cannot be allocated. C calloc() The name "calloc" stands for ...
The calloc() function is similar to malloc() function, but it initializes the allocated memory to zero. Unlike malloc() function, it allocates memory for an array of elements, initializing all elements to zero.Syntax:void* calloc(size_t num, size_t size); ...
Now the question is: why is a dynamic array allocated on the stack at all? Furthermore, if I change only JBUF from POINTER to ALLOCATABLE, and I keep the rest of the code as is, then my test run fine, even with the original stack size (=10240 kbytes). This seems to...
The aliasing behavior of internal pointers of dynamically-allocated memory is used to disambiguate memory accesses and to eliminate false data dependencies. It is determined whether a dynamically-allocated array will behave like a statically-allocated array throughout the entire program execution once it...

‘vector_resize’ function is called if certain conditions are met on addition or deletion. If the current vector capacity has been exhausted when an addition has been requested the size is doubled and the vector contents re-allocated. In a similar fashion, upon deletion, if the vector is a...

Having Fortran de-allocate memory that was allocated in C, or vice versa, is sure to cause trouble. The following modification of your code works on Windows 32-bit (but it is a quick-and-dirty fix-up, which you should sanitize and adapt for Linux symbol naming conve...
C as the language of implementation this post will guide you through building a simple vector data-structure. The structure will take advantage of a fixed-size array, with a counter invariant that keeps track of how many elements are currently present. If the underlying array becomes exhausted,...
