C++ Better Explained
87 pages that replace the 1,300-page textbook. Written for people with no programming background, using analogies and diagrams instead of jargon.
- Analogies for Dummies Every hard idea mapped onto something you already understand, so it lands the first time instead of the fifth.
- Vivid Code Diagrams Visual breakdowns that stick in your head, so you recall them under exam or interview pressure.
- Logic Made Simple The hard parts broken down to a level anyone can follow, without the university jargon.
30-day, no-questions-asked money-back guarantee.
The diagrams are what sets your book apart. Lines and lines of code mean nothing to someone who is a visual learner. Your diagrams make understanding much easier.
I always perceived learning C++ as very daunting and challenging, but I really liked how Sahil put things into pieces and goes straight to the point.
I have experience in many other languages. I do like the direct approach and feel this will be a good reference for beginning programmers.
