[英]c++, “Error: initialization with '{…}' expected for aggregate object”
[英]error: initialization with “{…}” expected for aggregate object - c++
struct test
{
unsigned int test1;
unsigned char test2[4096];
unsigned int test3;
} foo
struct foobar
{
unsigned char data[4096];
}
如果我想访问结构,我会说 foo.test1、foo.test2[4096] 等等。但是,当我希望以下列方式返回 foo.test2 中存在的数据时
pac.datafoo = foo.test2[4096];
unsigned char data[4096] = pac.datafoo;
这是我得到的错误:
error: initialization with "{...}" expected for aggregate object
我在做什么错误?
你需要学习数组初始化方法。 它不是简单地分配为单个变量。
一些例子:
int arrayone[3] = {0}; // assign all items with 0
int arraytwo[3] = {1, 2, 3 }; // assign each item with 1, 2 and 3
int arraythree[3]; // assign arraythree with arraytwo
for (int i = 0; i < 3; ++i) {
arraythree[i] = arraytwo[i];
}
添加 ”;” 在结构的末尾。
struct test
{
unsigned int test1;
unsigned char test2[4096];
unsigned int test3;
} foo ;
struct foobar
{
unsigned char data[4096];
} ;
unsigned char * data;
data = pac.datafoo;
