我想在一个结构体中有两个数组,它们在开始时被初始化,但需要进一步编辑.我需要三个结构的实例,所以我可以索引到一个特定的结构,并按照我的意愿修改.可能吗？
这是我以为我可以做但我得到错误：
struct potNumber{
int array[20] = {[0 ... 19] = 10};
char *theName[] = {"Half-and-Half","Almond","Rasberry","Vanilla",…};
} aPot[3];
然后我访问结构如下：
printf("some statement %s",aPot[0].array[0]);
aPot[0].theName[3];
…
解决方法
结构本身没有数据.您需要创建struct类型的对象并设置对象…
struct potNumber {
int array[20];
char *theName[42];
};
/* I like to separate the type definition from the object creation */
struct potNumber aPot[3];
/* with a C99 compiler you can use 'designated initializers' */
struct potNumber bPot = {{[7] = 7,[3] = -12},{[4] = "four",[6] = "six"}};
for (i = 0; i < 20; i++) {
aPot[0].array[i] = i;
}
aPot[0].theName[0] = "Half-and-Half";
aPot[0].theName[1] = "Almond";
aPot[0].theName[2] = "Rasberry";
aPot[0].theName[3] = "Vanilla";
/* ... */
for (i = 0; i < 20; i++) {
aPot[2].array[i] = 42 + i;
}
aPot[2].theName[0] = "Half-and-Half";
aPot[2].theName[1] = "Almond";
aPot[2].theName[2] = "Rasberry";
aPot[2].theName[3] = "Vanilla";
/* ... */
