Few small points

1) int new; is valid i c but int new is invalid in c++ as new is keyword in c++.
2) The C++ standard enforces that the __cplusplus macro will always be defined in C++ programs. Not the C standard obviously!
3) boolean result

printf("%d",sizeof(1==1)); // output = 4 in C (which is size of int)
cout << sizeof(1==1); // output =1 in c++ (which is the size of boolean datatype)

Let me put some context of my curiosity -
One of the mysterious activities in Programming Language design is the aspect of standard libraries and there have been talk of "modernizing" standard libraries to meet up to the requirements:
i) Parallelism(multi-core)
ii) Searching
iii) Big data
iv) GUI lacking in C & C++
v) The top N widely used algorithms

Now as a developer I am interested to know, Is there a precise formula for the evolution of Standard Libraries and measure its effectiveness?
