c - const static int 数组

Question

我在标题中有变量:

const static int RED = 0;
const static int BLUE = 1;
const static int GREEN = 5;
const static int DOG = 8;
const static int CAT = 9;
const static int SNAKE = 7;

如何创建全局数组并使用这些 const 的值初始化它们变量？

我尝试过:

const static int color[3] = {BLUE, GREEN, DOG};
const static int animal[3] = {DOG, CAT, SNAKE};

但是编译器说错误:

initializer element is not constant

(我需要创建一些可以循环的结构。)

您可以做的就是定义它们，以便这些值在编译时保持不变:

#define RED 0
#define BLUE 1
#define GREEN 5

const static int color[3] = {BLUE, GREEN, DOG};

或者您可以在运行时设置数组中的所有元素:

const static int color[3];
color[0] = BLUE;
color[1] = GREEN;
color[2] = DOG;

for(i = 0; i < 3; i++){ 
  if(color[i] == BLUE)
     printf("\nColor nr%d is blue", i);
}
