结构或类中的数组初始化

Question

I was just studying about structures and classes. I created a sample structure for getting familiar with it and tried to initialize an array in it. when I compiled the program it gave me error

error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘=’ token
char arr[5] = {2,3,8,67,87};

struct abc{
char a;
char b;
char c;

char arr[5] = {2,3,8,67,87};
};  

struct abc xyz[5]; 

Is array initialization not allowed in declaration of a structure as well as class ?

Answer 1

I guess in C you can do like this:

struct abc{
char a;
char b;
char c;

char arr[5];
};  

struct abc test= { 5, 2, 3, { 'a', 'b', 'c', 'd', 'e' } };

Answer 2

In C, you cannot initialize members of a structure in the structure definition. You have to do it when you declare a variable of that structure. In C++, you can do it as part of the constructor.

Answer 3

Completed array initialization is not allowed in struct but you can just initialize the name and type of array without the content. In c++

struct student{
int age;
string name;
int scoreOf4subject[4];   
}; 

When you need to set the 4 subjects value in array,it would be like:

student keny;   
keny.scoreOf4subject={90,91,94,93};
