问题: LabWindows/CVI是否支持变长数组?

解答:

有两种声明数组的方式:

  • 静态数组:
          int myArray [25];

          数组长度在声明数组时指定。

  • 动态数组:
          int * myArray;
          myArray = malloc (25 * sizeof(int));

          这些数组的长度被定义为动态分配给它的内存大小(malloc或realloc)。

    这两种方法都被LabWindows/CVI支持。另一种方式，是将变长数组的长度通过存放在一个特定变量中的数值来定义。

  • Variable Length Arrays:
          int arrayLength = 25;
          int myArray [arrayLength];

    ANSI 89不支持变长数组。由于LabWindows/CVI严格遵循ANSI 89标准，因此您不能在CVI中定义变长数组。
