【结构声明】
//结构数组定义
struct names {
char first[LEN];
char last[LEN];
};
struct guy {
struct names handle;
char food[LEN];
char job[LEN];
float income;
};
//结构数组初始化
struct guy fellow[2] = {
{{"enent","villard"},
"grilled salmon",
"personality coach",
6812.0
},
{{"wnter","swillbelly"},
"tripe",
"tabloid editor",
4300.2
}
};
声明结构指针
struct guy * him;
关键字struct、结构标记guy、指针标志 * 、其后是指针名。
如果barney是一个guy类型结构变量，则
him = & barney;
若fellow是一个结构数组，那么fellow[0]是一个结构，him指向可以写作
him = &fellow[0];
[指针访问结构成员]
如果him是指向guy类型结构的barney指针，则
//假设him = &barney
barney.income == (*him).imcome == him -> imcome
同样
//him == &fellow[0]
fellow[0].income == him -> income == (*him).income
