Template Deduction for C++

Template is a confusing and hard features in C++ if you want use it well, and I think it is also one of the reason which causes c++ programmers cannot understand each other. Sometimes the Deduction rule for c++ is really confusing, you don’t understand why you code doesn’t work or why it works. And Since STL heavily uses nesting Templates, both your compiler and your mind suffers from that.

Everything you do I can do it with a double pointer in C

It is 2016, low level coding is not needed anymore. We have programming languages like javascript and python. When people code everything with a class and related methods. But do you remember we have a programming language called C? When we had no class, templates, operator-override or implicit constructor at esthat time. You actually know what are doing with C, no magic! I claim no expert to programming, since I only have a four-year-old programming life.
