c - 如何在结构体数组中设置常量值？

Question

typedef struct all{
  int x;
  int ast[5];
}ALL;

ALL x[5];

int main(void){
  ALL y[5];
  // ...
}

如何为 ast[5] 设置常量值，以便所有数组变量都具有相同的 ast[] 值？

Answer 1

typedef struct all {
  int x;
  int ast[5];
} ALL;

ALL x[5];
ALL constast = {0, {1, 2, 3, 4, 5}};

int main(void) {
  ALL y[5] = {[0] = constast, [1] = constast, [2] = constast,
              [3] = constast, [4] = constast};
  // ...
}
