It depends on your definition of "object". I hate to nit-pick, but for
me, "object" may
contain data or code or both data and code. So with this definition, C
implements objects
without code.
For example, in C, a "struct" is a template used to instantiate objects
which only implement data,
whereas in C++, a "struct" is a template used to instantiate objects
which implements both data and code.
You can just replace the "class" keyword with "struct":
Compiles only with C++:
struct foo {
int a;
void m() {int b=0; b++;}
};
Compiles with both C and C++ compilers:
struct foo {
int a;
/*void m() {int b=0; b++;}*/
};
Of course, in addition to template classes, C++ has (generic) class
templates and many other features, as you stated.
