Contains C programming tutorial for beginners with lot of examples explained. This tutorial contains each and every feature of C programming that. C Programming. C.
I mean programmer, well by reading this tutorial maybe we'll be. First a little about C and its derivative C++. It is considered to be the most commonly used programming language. If you want a job in. But what makes C the language that. Well, its been around for quite some time.
The original C since the 7. C++ since the early 8. C is the most versatile. C permits just about anything, allowing programmers to write straight.
Its code runs very fast. Note that this tutorial will not cover C++ (C with. Table of Contents. This tutorial is meant to be a brief introduction to C, it is by no means exhaustive. If you. need more information try looking at our Other Resources.
Learning a programming language is a lot like learning a language that people speak like. German or French. The best way to learn a 'human' language is to start speaking, listening.
The same can be applied to C, you need. So, this tutorial will provided a lot.
If you've ever read another tutorial or a book on a programming language, then you've probably. The hello world program. It is a perfect starting place for. So, type the following program into your favorite editor. If you are using Windows. DOS Edit, if using a *Nix variant use VI or emacs.
Without further adew here. Hello World\n"); // print to screen. Save this code into a file, and call the file hello. If you are using *Nix you should have an a.
Windows. you might be wondering what is gcc, and where do I type the above line into. On Windows getting. C is little bit more difficult than with a *Nix variant.
You can get. a variation of gcc to output Windows code called DJGPP. Setting up the compiler is probably the hardest part to getting started programming, and. DJGPP. Another compiler option is to get. Microsoft Visual C++, an excellent editor, with lots. The draw back is that. But if you can afford a copy, get it.
If you have Visual C++. File, then New, then select Win. Console application from the.
Type in a project name, and then press ok. Next it will ask you what it should. Select the hello world application, and then you should get a program very. F7 compiles, and Ctrl- F5 will run it. From now on the tutorial will.
Nix method and output files. If you compiled the program in Windows instead of. Nix you would have a hello. Note: If you are coming from. The reason is the gcc with the devkit advance is for the gameboy, so the code it generates will. PC, also becuase the gameboy has no standard font built in, you will not be able. This creates an executable file a.
The result is that the characters. Hello World are printed out, preceded by an empty line. A C Program contains functions and variables.
The functions specify the tasks to. The above program has one function called main. This. function tells your program where to start running. All. C codes must have a main function. Also notice that C is case- sensitive.
The commands have to be written. C also denotes the end of statement with a semi- colon like Java & Pascal. Brackets signify either to "{" begin a group of.
The // or /* comment */. Anything after two slashes the compiler ignores. The last. part of the program you should notice is the #include. This simply includes a group of functions from the filename specified between. The file above stdio. C to use, the. function the our above. Printf takes a string of.
Now that you understand the hello world program it's time to learn more about. Here is our next program to discuss. It declares several variables, performs some. How many lollipops do you want: ").
Please pay %f to the cashier!\n", cost). This program when run, well prompt the user for how many lollipops they would like. After. they enter a number and press enter, it will print out how much it will cost them to buy.
The main, {} brackets, comments, and include should be familiar. The new part of this. First lets talk about the variables. This program. has two variables numcandy, and cost. These are the names of the variables. Before a variable can. Declaring a variable in C is easy, you simply tell the compiler the.
So in the above example. The line int numcandy; tells the.
Then you can simply use numcandy through out your. Integers are non decimal numbers like - 1. The other variable in. Next the scanf, and printf statements. After running the program you will notice that the scanf function.
It waits for the user to enter a number, and then press enter. It puts. this value into our variable numcandy.
Next notice some special character sequences contained in. First the printf has the sequence "\n". This sequence simply means move to the. Next we have the %f and %d. These tell printf and scanf what type of variables to expect. So if you changed the above programs printf line to ..
You need to make sure the "%" go with the right types. Variable names are arbitrary (with some compiler- defined maximum length. C uses the following standard variable types: int - > integer variable. The printf function can be instructed to print integers, floats. The general syntax is printf( "format", variables ).
Some useful formats are. So using this new knowledge, you could change the above program where it prints the cost to .. Look back up at the program one more time at the line.
This is the math of the program. This line is fairly self explanatory. It takes the value. Here are a list of the standard.
Now that we've covered printf and the basic data types, we can move onto program control meaning loops and conditions. Real programs are than just getting input, performing some math, and then printing out the results. The next obvoius step would be to add some sort of control. Like for the above example program if they put in that they wanted to. We could print out, that the store doesn't have that many. This section. will describe the basic loop and condition statements available in C, and then will end with a short example. First Conditional statements.
C has three types of conditional statements if, else, and switch. Here is the syntax for if and else: if (condition_1). Either by omitting branches or by. Meaning having an if inside of another if. Now. that we can make an if we need to make the condition that goes inside of the parenthesis. Conditions are logical operators involving the comparison of quantities (of the same.
Here are a list of the basic conditional operators. Now that you know the operators here are some sample conditions. For instance using the above. The store does not have that much candy in stock!"). The boolean operators are for combining more than one condition into a single. So for instance if (money> 5.
This condition would only be true if both money was greater than 5. If you. replace the & & with || then the condition would. OR cost less than 1. I think you get the picture. Another couple things to notice about conditional statements in C is that the equality operator. The. single equals sign as we learned in lesson two is the assignment operator. You use it to assign values to variables.
Remember THIS! It is very important. Next with C conditional statements you can also omit (leave out) the operator. This would evaluate to true.
Understand? If you have no operators inside the parenthesis then C will simply check to see if the value is anything. Another conditional use is in the switch construct: switch (variable). The appropriate block of statements is executed according to the value of. The break statements insure that the statements in the cases. If you would want to execute. This. construct is particularly useful in handling input variables. Here is an example, if you had a integer variable called race position.
First place, you get gold!\n"). Second place, you get silver!\n"). Third place, you get bronze!\n"). You dont get anything, you lose!\n"). You could have easily done this same thing with three if's and and else.
But we wanted to. As an excersize rewrite the above code segment to use if's instead of the switch. That's it for conditional statements, now we come to the next part of lesson three loops. C provides two. basic types of loops a while and a for loop. While and for loops continue to repeat basically until.
Here is the syntax for while and for loops. The while loop continues to loop until the. The condition is tested upon entering the. Any logical construction (see below for a list) can be used in this. The for loop is a special case, and is equivalent to the following. For instance, the following structure is often encountered: i = initial_i.
This structure may be rewritten in the easier syntax of the for. Infinite loops are possible (e. C permits you to write an infinite loop, and provides. For example. consider the following (admittedly not- so- clean) re- write of the previous loop: angle_degree = 0.
The conditional if simply asks whether angle_degree. Finally, to wrap up lesson three we will. You can define constants of.
Its syntax is. simple- -for instance #define ANGLE_MIN 0. ANGLE_MAX 3. 60. would define ANGLE_MIN and ANGLE_MAX to the values 0. C distinguishes between lowercase and uppercase letters. It is customary to use only capital letters in defining global.
Then inside your program you could insert ANGLE_MAX anytime you wanted to use the. Now here is the sample program. You should be able to understand all the code there in. Basically there is a #define for a number of lollipopps, and you sell lollipopps until you. Then after all are.
START_NUMBERLOLLIPOPS 1. MAX_AT_ONCE 3. START_NUMBERLOLLIPOPS; // set start value to our constant.
How many lollipops do you want (- 1 quits): ", numberlollipopps). MAX_AT_ONCE || numcandy < = 0 || numcandy > numberlollipopps). You cannot have that many, enter another number\n"). Please pay $%. 2f to the cashier!\n", cost). All the lollipopps have been sold for : $%. The C language takes a lot of flack for its ability to peek and poke directly into.
This gives great flexibility and power to the language, but it also makes it. Arrays are. very interesting since they can be accessed through pointers or array syntax, that is why.
