visual studio array assignment

Question

this code gave me error:

//Foo.h
class Foo
{
//something...
private:
int a, b, c[2];
};

//Foo.cpp
Foo::Foo()
{
int c = {0,0};
}

WWHHHYYYY???

Answer 1

first of all you forgot to declare the constructor in the class definition,declare it in public section of the class:
//Foo.h
class Foo
{
//something...
public:
Foo();
private:
int a, b, c[2];
};

second, you cannot assign directly to an array after its declaration same as you do:

//Foo.cpp
Foo::Foo() {
c = {0,0};
}

you have to either assign the value at declaration or use loop to assign elements, since your array seems to be a member variable, you can also initialize it in the constructor initialization list like that:

Foo::Foo(): c{0} /*every element in c is set to 0*/ {

}

or

Foo::Foo(): c{10,200} /*assign elements*/ {

}

Answer 4
