C++ strerror() Function Example | strerror() in C++

C++ strerror() is an inbuilt string handling function that returns the description of the type of system error that occurred in the program. It is defined in <string.h> header file. It takes an integer parameter, which represents the error code. With the help of this function strerror(), we covert the error code in the string, which shows the error in the text format. This strerror() function is often compared with perror(). They both return the identical error description.

C++ strerror()

The strerror() method in C++ returns the textual description of a system error code. The strerror() takes the argument: ernum, which is the integer value that represents an error code. The strerror() method converts the error code to the suitable string that describes the error. The description returned by strerror() function is identical to that of perror(). The program must not modify the returned string. But it may be overwritten by the subsequent call to the strerror().

Syntax

char* strerror( int num );

Popular String Fuctions in C [With Examples]

Strings in C language are an array of characters ended with null characters (‘\0’). The null character at the end of a string indicates its end and the strings are always enclosed by double-quotes. In C language characters are enclosed by single quotes. Some examples of both of them shown below;

Example or Representation of C Characters and Strings

  • char string[10] = { ‘s’,’d’,’f’,’d’,’t’,’j’,’a’,’\0’ };
  • char string[10]=” fresher”;
  • char string[]=” fresher”;

There is a minor difference between the declarations of the strings in both of the above statements. Like when we declare char as string[10], 10 bytes of memory space gets allocated to hold the 10 values of string, while when we declare it like string[] then memory gets allocated at the time of execution of the program.

A Guide to using the strdup() function in C/C++

In this article, we’ll take a look at using the strdup() function in C/C++.

The strdup() function is very useful if you want to duplicate the contents of a string onto another string.

Let’s see how we can utilize this function, using some simple examples.

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. VimSublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.
