Introduction to C++ Programming, Lecture notes of Programming for Engineers
The simplest possible c++ program and outlines how it can be made into running code for beginners who want to become professionals. It is a course in the c++ programming language for students who want to become language lawyers and assumes they are bright but not (necessarily) geniuses and willing to work hard. After the course, students will be able to write small colloquial c++ programs and read much larger programs.
