Dear all,
To do below is too long.
cout << "Name: " << name << ", Age: " << age << endl;
Can cout use "%" to implement?
Thanks.

If 20 characters of typing is enough to make you want to avoid
type safety, then I don't C++ is the language for you. :)

No.

Why it is too long?
If you would remove the spaces around the '<<' operators (just like the
printf), the cout version is only 4 character longer. That seems to be a
small price to pay for the type safety you get with cout.
Can cout use "%" to implement?
No.

No, but boost do a format library that adds this to C++ http://www.boost.org/libs/format/index.htm

Your two examples are not equivalent. In the version using cout you flush
the output stream, whereas in the printf version you don't.

Removing unnecessary whitepace and using
same newline expression in order to form
a valid comparision:
printf("Name: %s, Age: %d\n",name,age) ;
cout<<"Name: "<<name<<", Age: "<<age<<'\n ';
Is an extra four characters really too high
a price to pay for type safety?

I suppose one could write some code to simulate
it, but what's the point?
Also note that 'printf()' is just as valid
(but less safe) a function in C++ as are the
stream inserters.
If you insist upon using '%' specifiers, why not just
use 'printf()'?

I've read that... AClass ac = AClass( "name", 23 );
is less efficient than... AClass ac( "name", 23 );
because the first has to create a temporary object which is then
assigned to ac.
However, I can't seem to prove this true. I've created a class
containing the following constructors and overloaded equal operator.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
