学点 C 语言(25): 数据类型 - 结构数组与结构指针
1. 结构数组:
#include
int main(void)
{
struct Rec {int x,y;};
struct Rec rs[10];
size_t i;
for (i = 0; i < sizeof rs/sizeof rs[0]; i++) {
rs[i].x = i;
rs[i].y = i * 2;
}
for (i = 0; i < sizeof rs/sizeof rs[0]; i++) {
printf("%d, %dn", rs[i].x, rs[i].y);
}
getchar();
return 0;
}
#include
int main(void)
{
struct Rec {
char name[12];
short age;
} rs[3] = {
{"AAA", 11},
{"BBB", 22},
{"CCC", 22}
};
size_t i;
for (i = 0; i < sizeof rs/sizeof rs[0]; i++) {
printf("%s, %dn", rs[i].name, rs[i].age);
}
getchar();
return 0;
}
2. 结构指针指向已存在的结构数组:
#include
int main(void)
{
struct Rec {
char name[12];
short age;
} rs[3] = {
{"AAA", 11},
{"BBB", 22},
{"CCC", 22}
};
struct Rec *p = rs;
printf("%s, %dn", p->name, p->age);
printf("%s, %dn", (p+1)->name, (p+1)->age);
printf("%s, %dn", (p+2)->name, (p+2)->age);
getchar();
return 0;
}
