C++ Functions Example | What is Function in C++

C++ Function is a group a statement that performs a specific task. A function is the block of organized, reusable code that can be used to perform the single, related action. The good thing about the functions is that they are famous with many names.

What is Function in Programming Language

Different programming languages name them differently, for example, functions, methods, subroutines, procedures, etc. If you come across any such terminology, then imagine the same concept.

Functions provide better modularity for our application and a high degree of code reusability. You have already seen various functions like printf() and main().

Why do we need functions?

Suppose in a program there is a task which is performed at several places. So, with different values, we are delivering the same task. This makes our code look lengthy and naïve.

Functions come to the rescue where we can define the task to be performed at one place and pass parameters as required and get a similar result. Functions make our code modular and more professional.

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++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

  1. Using multiple variables in the print function
  2. Comparing Signed integer with unsigned integer
  3. Putting a semicolon at the end of the loop statement
  4. C preprocessor doesn’t need a semicolon
  5. Size of the string matters
  6. Macros and equations aren’t good friends
  7. Never compare Floating data type with double data type
  8. Arrays have a boundary
  9. Character constants are different from string literals
  10. Difference between single(=) and double(==) equal signs.

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

  1. %d indicates Integer Format Specifier
  2. %f indicates Float Format Specifier
  3. %c indicates Character Format Specifier
  4. %s indicates String Format Specifier
  5. %u indicates Unsigned Integer Format Specifier
  6. %ld indicates Long Int Format Specifier

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.
