Hello, guys! I am a new staff in learning C++.
I just wonder why we should learn PDL pseudocode before we start write code.

1. better make the subject of your questions as "why we should learn PDL pseudocode before we start write code" instead of "May I have a question?" the latter is too general.
2. C++ is just a language. it is used to expres your thoughts as other English and Chinese. So when you want to write a program, you will first form some thoughts, the express it by C++. Pseudocode is a good way to "form" these thoughts.

With thoughts, you can express your program in C++, C, java, ...
Without thoughts, you will probably fail in coding.

Now I know that's why we have to learn that kind of thinking staff.

actually, before using pseudo code, you can use English or Chinese to describe the problem first. If you fail on that, you will probably fail on describing it using pseudo code/c++.
