C++11 - Right angle bracket

In C++03 ">>" is always interpreted as right shift operator. It causes problem for nested template declaration like here:
In above example for C++03 we have compilation error because of unintended interpretation of ">>". Compiler interpret it as right shift operator - not like two nested vectors. Proper syntax in above situation should include space character between two ">" characters closing nested templates like here:
It it not very comfortable and sometimes causes problems with finding reason of compilation error. Fortunately, C++11 standard solves that problem. It implements proper interpretation of nested templates without space between two right angle operators ">". Therfore in C++11 following syntax:
is properly interprated as two nested vectors.

    I like that change very much. It was very anoying syntax for nested templates in previous C++ version.

Advanced C++ - Stack unwinding

Stack unwinding is normally a concept of removing function entries from call stack (also known as Execution stack, Control stack, Function stack or Run-time stack). Call Stack is a stack data structure that stores active functions' addresses and helps in supporting function call/return mechanism. Every time when a function is called, an entry is made into Call stack which contains the return address of the calling function where the control needs to return after the execution of called function. This entry is called by various names like stack frame , activation frame or activation record. With respect to exception handling , stack Unwinding is a process of linearly searching function call stack to reach exception handler. When an exception occurs, if it is not handled in current function where it is thrown, the function Call Stack is unwound until the control reaches try block and then passes to catch block at the end of try block to handle exception. Also, in this proc...
