Compiler Error C2073

Error Message

'identifier' : elements of partially initialized array must have a default constructor

Too few initializers were specified for an array of user-defined types or constants. If an explicit initializer and its corresponding constructor are not specified for an array member, a default constructor must be supplied.

The following sample generates C2073:

// C2073.cpp
class A {
   A( int );   // constructor for ints only
A a[3] = { A(1), A(2) };   // C2073, no default constructor
// C2073b.cpp
// compile with: /c
class B {
   B();   // default constructor declared
   B( int );
B b[3] = { B(1), B(2) };   // OK
