How to initialize 'const int var[5]' member of a class with 1,2,3,4,5?

Question

Keep in mind it is 'const'

Answer 1

A non static const array is cannot be initialize in constructor. Whereas you can initialize this from C++11 as shown below.

class test
{
public:
test () : var({1,2,3,4,5})
{}
const int var[5];
};

in main ()
test obj;
cout <<obj.var[0]<<obj.var[1]<<obj.var[2]<<obj.var[3]<<obj.var[4]<<endl;

Hope you understand this otherwise let me know the exact scenario which you are trying to address.

Answer 2

how will it work if i want pass its values from constuctor argument?

Answer 3

Guess, in a same way it will work. Take an argument in constructor and assign it to the array

test (arr) : var (arr){}

but not sure whether will it or not.

If not you can use the pointers instead of array.
