The world’s popular operating systems - Linux, Windows, and Mac OS X, their interfaces and file systems, are written in C the infrastructure of the Internet, including most of its networking protocols, web servers, and email systems, are written in C software libraries providing graphical interfaces and tools, and efficient numerical, statistical, encryption, and compression algorithms, are written in C and the software for most embedded devices, including those in cars, aircraft, robots, smart appliances, sensors, and game consoles, is written in C. The decision about whether C, C++, or Java is the best general-purpose programming language (if that question can be decided, or even needs to be decided), is not going to be an easy one.Ĭ is the programming language of choice for most systems-level, engineering, and scientific programming. Of course, all of these properties are independent of C and are traits of good programming in any high-level language.Ĭ has the high-level programming features provided by most procedural programming languages - strongly typed variables, constants, structured types, enumerated types, a mechanism for defining your own types, aggregate structures, control structures, recursion and program modularization.Ĭ does not support sets of data, Java’s concept of a class or objects, nested functions, nor subrange types and their use as array subscripts, and has only recently added a Boolean data type.Ĭ does have, however, separate compilation, conditional compilation, bitwise operators, pointer arithmetic and language independent input and output. Programs written in C can be described as ‘good’ programs if they are written clearly, make use of high-level programming practices, and are well-documented with sufficient comments and meaningful variable names. CĬ can be correctly described as a successful, general-purpose programming language, a description also given to Java and C++.Ĭ is a procedural programming language, not an object-oriented language like Java or C++. You can ask man to look only for library functions (section 3 of the manual) with man 3 printf. Most or all of these functions are documented in man pages, just like shell commands.įor some C functions there are shell commands with identical names if you type man printf, for example, you’ll see the man page for the bash printf command and not the C function printf(). ManualsĬ programming depends on a suite of standard libraries for input/output, strings, math, memory allocation, and so forth. It’s not bad, and there are lots of others, including some that you can get electronically, like Prinz’s C in a Nutshell (O’Reilly).

If you feel you need more of a C textbook, either use the one online or see the professor for recommendations of good ones.įor example, past incarnations of this course used the text by Bronson, A First Book of ANSI C. If I do reference it, I will use the shorthand “H&S”. The Harbison and Steele book is very highly recommended and is an excellent reference and learning resource.īut it is not a tutorial. There are many to choose from, including a good text online (see the Resources page). We elected not to require a specific textbook on C.

Our in-class activity is to compile and test guessprime4.c, and write a shell script to test it.

We will learn the following from today’s lecture: In the next lecture, we will learn more basics on C. This lecture will serve as an introduction to the C language.

We will spend the rest of the course developing our C and systems programming skill set by first understanding the basics of the language and then (through examples) study good code and write our own. The first few lectures have been a crash course in the shell and shell programming.
