The time you measure in the code is the CPU time of the running code.
No statements you write will ever be able to measure compile-time, as they are not executed when compiling.
It always give you runtime clock.
You should give a try on std::clock which is more reliable..
To use C++ templates for compile-time calculations, we can define a template class or function that takes one or more arguments and performs the calculation.
The result of the calculation is then used as a template parameter, which can be used in other parts of the program..
Definition: The date on which the compilation of the data was completed..
Compiling is the process of transforming C language source code into executable code.
Running is the process of executing the executable code.
Compilation needs to be done only once to produce the executable code.
The executable code thus produced can then be run multiple times..
__DATE__ is a preprocessor macro that expands to the current date (at compile time) in the form mmm dd yyyy (e.g. "Jan 14 2012"), as a string.
The __DATE__ macro can be used to provide information about the particular moment a binary was built.
The __TIME__ macro gets the current time of the build..
