- Many programmers struggle to write programs, even though they understand their chosen programming language. Programming isn't about syntax-it's about problem solving, and all good programmers can solve problems. Unfortunately, most programming books focus on syntax and semantics, resulting in programmers who can't make the leap from reading programs to writing them. Think Like a Programmer bridges that gap, teaching readers how to solve problems systematically, offering numerous techniques and examples designed to demonstrate how to organize thoughts, discover solutions, and find strategies to
