Ç编译错误：＆QUOT;可变大小的物体可能无法初始化＆QUOT; [英] C compile error: "Variable-sized object may not be initialized"

问题描述

为什么我收到错误可变大小的物体可能无法初始化具有以下code？

  INT boardAux [长度] [长度] = {{0}};
 

解决方案

我假设你使用的是C99编译器（带有支持动态大小的数组）。在code的问题是，在当编译器看到你的变量声明的时候就不能知道有多少元素在数组中（我也是这里假设，从长度编译器错误不是编译时间常数）。

您必须手动初始化数组：

  INT boardAux [长度] [长度];
memset的（boardAux，0，长度*长度*的sizeof（INT））;
 

Why do I receive the error "Variable-sized object may not be initialized" with the following code?

int boardAux[length][length] = {{0}};

解决方案

I am assuming that you are using a C99 compiler (with support for dynamically sized arrays). The problem in your code is that at the time when the compilers sees your variable declaration it cannot know how many elements there are in the array (I am also assuming here, from the compiler error that length is not a compile time constant).

You must manually initialize that array:

int boardAux[length][length];
memset( boardAux, 0, length*length*sizeof(int) );
