c - Struct fl 没有名为 sub 的成员

Question

#include <stdio.h>
#include <stdlib.h>

struct fl{    
  char sub[3] = {"Math","Science","ICT"};    
};

int main()
{    
    int i;

    struct fl floatp;

    for (i = 0; i < 3; ++i){    
        printf (" %s",floatp.sub[i]);    
    }

    return 0;
}

我在第 11 行收到此错误“struct fl 没有名为 sub 的成员”。但我确实有一个名为“sub”的成员。我做错了什么？

Answer 1

你想要这个:

#include <stdio.h>
#include <stdlib.h>

struct fl {
  char *sub[3];
};

int main()
{
  int i;

  struct fl floatp = {{ "Math","Science","ICT" }};
  // or if your compiler supports it:
  // struct fl floatp = {.sub = { "Math","Science","ICT" }};

  for (i = 0; i < 3; ++i) {
    printf(" %s", floatp.sub[i]);
  }

  return 0;
}
