C Programming in One Hour a Day: Microsoft Excel

Autor Bradley L. Jones, Peter Aitken, Dean Miller
en Limba Engleză Paperback – 10 oct 2013

Sams Teach Yourself C in One Hour a Day, Seventh Edition is the newest version of our 500,000+ copy best-seller Sams Teach Yourself C in 21 Days. Fully revised for the new C++11 standard and libraries, it now emphasizes platform-independent C programming using free, open-source C compilers rather than proprietary IDEs. This edition strengthens its focus on C programming fundamentals, and adds new material on C-based object-oriented programming languages (e.g., Objective-C). Replete with carefully explained code, syntax examples, and well-crafted exercises, this is the broadest and deepest introductory C tutorial available. It's ideal for anyone who's serious about truly mastering C - including thousands of developers who want to leverage its speed and performance in modern mobile and gaming apps.

Friendly and accessible, it delivers step-by-step, hands-on experience that starts with simple tasks and gradually builds to professional-quality techniques. Each lesson is designed to be completed in hour or less, introducing and clearly explaining essential concepts, providing practical examples, and encouraging you to build simple programs on your own. Coverage includes:

  • Understanding C program components and structure
  • Mastering essential C syntax and program control
  • Using core language features, including numeric arrays, pointers, characters, strings, structures, and variable scope
  • Interacting with the screen, printer, and keyboard
  • Using functions and exploring the C Function Library
  • Working with memory and the compiler
  • And much more
