尝试编译使用结构的 C 源文件时出现错误。我在 Ubuntu 12.04 LTS 上使用 gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3。
这是代码:
/* struct.c: Illustrates structures */
#include <stdio.h>
#include <string.h>
struct Hitter {
char last[16];
char first[11];
int home_runs;
};
int main() {
struct Hitter h1 = {"McGwire", "Mark", 70};
struct Hitter h2;
strcpy(h2.last, "Sosa");
strcpy(h2.first, "Sammy");
h2.home_runs = h1.home_runs - 4;
printf("#1 == {%s, %s, %d}\n",
h1.last, h1.first, h1.home_runs);
printf("#2 == {%s, %s, %d}\n",
h2.last, h2.first, h2.home_runs);
return 0;
}
这是错误:
$ gcc -o struct struct.c
struct.c: In function `main':
struct.c:12:9: error: parameter `h1' is initialized

以上代码来自 Chuck Allison 的 CD 培训课程“Thinking in C”。我知道那是一张非常旧的 CD,而且我确信结构的语法一定已经改变,但我不知道它现在可能是什么。感谢您的帮助。谢谢
