Dynamic memory allocation in COverview of memory management

Sometimes the size of the array you declared may be insufficient. To solve this issue, you can allocate memory manually during run-time. This is known as dynamic memory allocation in C programming. To allocate memory dynamically, library functions aremalloc(),calloc(),realloc()andfree()are use...
Last year and early this year, I wrote a couple of articles on dynamic allocation in C and C++ emphasizing the distinction between allocating objects and allocating raw (uninitialized) storage.1-2 When a program allocates an object, it n... S Dan - 《Embedded Systems Design》 被引量: 0...

in the collection. Along with this, a ‘items’ variable with a pointer of void pointers is included, allowing us to insert a heterogeneous collection of elements into the vector. The ‘vector_resize’ method is defined to be ‘static’ resulting in successful execution of the function only ...
A Fahmia,M Asvialb,D Gunawanc 摘要: In this paper, we proposed Dynamic Chunk Allocation based on channel condition using a Modified Greedy Algorithm in SC- FDMA system. Simulation is performed on the uplink direction and it is assumed that channel state information (CSI) of all users are...
