Dynamic Memory allocation is the process of allocating the memory during runtime. int arr[p] This code creates a static array in memory of size p,whose size can't be altered at runtime,but with dynamic memory allocation functions you can alter the size by using the realloc funntion. Sh...
Also, it returns NULL if the memory is insufficient for allocation. As a tutorial or an example of dynamic memory allocation using malloc in C, if you write the statement malloc(10), it will dynamically allocate 10 bytes of memory. Note that malloc doesn’t initialize the memory during exec...

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...
这一种方法在计算机编程中,个人以为是动态内存分配(Dynamic Memory Allocation),目标不是计算最终结果,而是为一段段代码中的许多“物理对象”获得相应大小的一段内存间。 程序设计中定义的大多数临时变量(物理对象),由于编译器在编译和链接过程中,会根据变量的类型确定它的内存空间大小,随后,操作系统根据“已知信息”...
解析:这是一道动态内存分配(Dynamic memory allocation)题。 尽管不像非嵌入式计算那么常见,嵌入式系统还是有从堆(heap)中动态分配内存的过 程。 面试官期望应试者能解决内存碎片、碎片收集、变量的执行时间等问题。 这是一个有趣的问题。故意把0值传给了函数malloc,得到了一个合法的指针,这就是 ...
