| 1 对成员赋值.
1.1 用{}形式.
struct st1 st1 = {1,2,3);
1.2 linux kernel风格.
struct st1 st1 = {
.a = 1;
.b = 2;
};
2 对整体赋值.
struct st1 a, b;
b = a;
3 结构体作为函数返回值对另一个结构体赋值.
struct st1 func1();
struct st1 a = func1();
举例:
[ctest]# vi t.c
#include
struct st1 {
int e1;
int e2;
};
struct st1 func1()
{
struct st1 h = { 77, 88};
return h;
}
int main()
{
struct st1 a = { 33, 44};
struct st1 b = {
.e1 = 55,
};
struct st1 c;
struct st1 d;
c = a;
d = func1();
printf("e1 e2 is %d %d\n", a.e1, a.e2);
printf("e1 e2 is %d %d\n", b.e1, b.e2);
printf("e1 e2 is %d %d\n", c.e1, c.e2);
printf("e1 e2 is %d %d\n", d.e1, d.e2);
return 0;
}
"t.c" 29L, 420C written
[ctest]# gcc -o a t.c
[ctest]# ./a
e1 e2 is 33 44
e1 e2 is 55 0
e1 e2 is 33 44
e1 e2 is 77 88 |
