C Constants

Summary: in this tutorial, you will learn how use C constants in your code to make your code more readable and easy to maintain. There are a lot of cases you want to use a constant in your code for example to calculate the square of a circle you code as follows:

As you see, the C constants make your code readable and the symbolic constants tell you not only the value but also its meaning. In addition, if a constant is used in several places, it is better to use symbolic constant because when you want to change its value you just have to change it in one place that define the constant, see the below example:

Later on if the tax rate changes, you only have to change it in where it is defined.But how do you define symbolic C constants? The first idea of defining a C constant is using C preprocessor as follows:

By doing this, when your program compiled, the constant values 1.14159 and 0.1 will be substituted everywhere you used PI and TAXRATE. This feature is known as compile time substitution. Those defined constants are called manifest constants because when you run the program, all the substitutions have already been made.

Note that there is no equal sign between constant’s name and value and there is no semicolon (;) at the end of the statement.

It is highly recommended that you use constant name is upper case so when you see it in code you know that it is a constant. The formula of defining a constant is as follows:

C Write Text File

Summary: In this tutorial, you will learn how to write text file using standard I/O functions. Here are the steps of writing strings into a text file line by line: Open the file for writing using fopen function with mode “w”. It is important to note that in this mode the file content is deleted and the file is overwritten if it exists.Use function fprintf to write text into the file stream.Use function fclose to close the file.In the source code below we will write 10 lines of text into a text file

1.txt in the c:\temp directory.

/* * Author: http://cprogramminglanguage.net *

Description: C Write text file demo */

#include<stdio.h>

#define LEN 256
int main (){
FILE * fp;
int i;

/* open the file for writing*/

fp = fopen ("c:\\temp\\1.txt","w");

/* write 10 lines of text into the file stream*/

for(i = 0; i &lt; 10;i++)

{

fprintf (fp, "This is line %d\n",i + 1); }

/* close the file*/

fclose (fp);

return 0;

}

In this tutorial, you’ve learned how to write text file using function fprintf().

C File I/O

Summary: in this tutorial, you will learn how to use standard I/O functions to deal with file in C.

C provides a set of standard I/O functions that allow you to deal with file effectively. To access a file, you first need a file pointer which is a memory address of the file.

Before you process a file you need to open it. C provides fopen function to enable to open a file for different purposes in various modes:

In the fopen function above:

You pass the file name as to the first argument *file_nameYou can have various modes for the mode parameter. The table below provides the modes that C supports.The fopen() function returns a NULL pointer if the file does not exist or write-protected.Open file for writing. If the file exists, fopen function deletes content and overwrites it otherwise a new file is created.Open file for appending. The fopen function creates file if it does not exist.Open file for reading and writingOpen file for reading and writing. The fopen function deletes content and overwrites the file if the file exists.Open file for reading and writing. The fopen function appends file if it the file exists

The above modes are applied to text file. For the binary file, you just add “b” at the end of each mode such as rb, wb, ab, r+b…etc. For example to open a text file test.txt in directory c:\temp you use the fopen as follows:

After process the file you must close it using fclose() function as follows:

The fclose() fuction flushes the stream pointed by file pointer *fp and close the file descriptor. The fclose() function returns EOF or error code to indicate the error if unexpected situation happens, otherwise it returns 0. For example, to close the text file test.txt pointed by file pointer *fp we use the fclose() function as follows:

In this tutorial, you’ve learned how to open file for different purposes such as reading, writing and appending using fopen function. You’ve also learned how to close a file using fclose function. In the next tutorials, you will learn how to read, write and append text and binary file.

We provide you several examples of using C comments in the demo program below:

In order to use comments effectively you can follow the following tips:

C comments should describe how a block of code or function does instead of telling how it works. For example, you should comment the code say “calculate area of a circle” instead of “multiple of radius, radius and PI”.C comments are used to help you and other programmers to understand the piece of code in the future. Therefore when you write C comments, ask yourself if you or other can understand it by reading comments only.

Developing C File Exists Checking Functions

Summary: in this tutorial, you will learn how to develop C file exists checking function by using various C built-in standard functions.

There are a lot of cases you want to check if a file exists before doing further processing such as backup, copy, modify or just read data from the file. However C does not provide any built-in function to allow you to check if a file exists. Fortunately, we can use other built-in functions to develop our own function check whether a file exists.

In this first approach, we will try to read the data from the file using fopen() function. If we can read the file, it means the file exists otherwise the file does not exist. Here is the C file exists function to check if a file exists using fopen() function.

In this second approach, instead of reading data from the file, we read attributes of the file using stat() function. The stat() function will return 0 if the operation is successful. Otherwise if file does not exist, it returns -1. We can make use of the stat() function to check if a file exists.

In this tutorial, you’ve learned how to use standard C functions to develop C file exists checking functions that check if a file exists.
