Question

What are the issues/difficulties that will could be faced by users/programmers if the dynamic memory allocation mechanizm woudn't exist

engineering Computer-Science

Answer 1

Answer #1

the various issues / difficulties that could be faced by users or programmers if the dynamic memory allocation mechanism would not exist are:-

1. size of memory can not shrink or grow during operation means it remain fixed . No memory variation during different state .

2 the allocation of variable is permanent means no concept of deallocation like free keyword in c and c++

3. No concept of memory optimization mean in there is chance of waste of memory

Introduction: One of the most important uses of pointers is for dynamic allocation of memory. In C++ there are commands that let the user request a chunk of memory from the operating system, and use this memory to store data. There are also commands to return memory back to the O/S when the program is finished using the data. In this lab, we will explore some of the things that can go wrong when using dynamic memory and discuss how...

Memory Allocation a) Is it possible to have both internal and external fragmentation with fixed partition memory allocation? How about with dynamic/variable memory partition allocation? Explain. (1 point) b) Suppose we have 1000K of memory where the first 100K is reserved. Also suppose that the following processes have been allocated memory in the following order: P1: 100K, P2: 100K, P3: 25K, P4: 200K, P5: 200K, P6: 75K, P7: 100K. Create a diagram of memory. Suppose that P2, P4, and P6...

Programs written in a language that supports pointers and dynamic memory allocation can suffer from dangling pointers and lost heap-dynamic variables (or garbages). (a) A dangling pointer is a pointer that contains the address of a piece of memory that no longer belongs to the program. Give one scenario that can cause dangling pointers. Support your scenario with sample codes in your favorite language. Poorly implemented languages leave the detection of the dangling pointer problem to the operating system. Suggest...
