什么是用C静态和动态数组之间的区别？ [英] What is the difference between static and dynamic arrays in C?

问题描述

  

可能重复：结果
  是数组名在C中的指针？结果
   C ++静态数组与动态数组？

我学习C和我在不同的是以下两个阵列之间有什么困惑：

  int类型的[10];
 

和

 为int * B =（INT *）malloc的（10 * sizeof的（INT））;
 

刚上最基本的层面，什么是这两者之间有什么区别？

解决方案

  int类型的[10];
 

分配堆栈并且作为范围结束后立即解除分配

 为int * B =（INT *）malloc的（10 * sizeof的（INT））;
 

被分配在堆和在整个程序的生存活着除非其明确地自由ð

I'm learning C and I'm confused at what the difference is between the following two arrays:

int a[10];

and

int *b = (int *) malloc(10 * sizeof(int));

Just on the most basic level, what is the difference between these two?

解决方案

int a[10];

is allocated on stack and is de-allocated as soon as the scope ends.

int *b = (int *) malloc(10 * sizeof(int));

is allocated on heap and is alive throughout the lifetime of the program unless it's explicitly freed.
