The scanf() function in C - Accepting userinput in C

In this article, we will be focusing on the scanf() function in C in detail.

Working of the scanf() function in C

Be it any programming language, we always need user input, in order to make it work with a dynamic set of values.

This is where the scanf() function in C comes into picture.

The scanf() function enables the programmer to accept formatted inputs to the application or production code. Moreover, by using this function, the users can provide dynamic input values to the application.

Having understood the working of scanf() function, let us now focus on the structure of the same.


Syntax of scanf() function

Let us have a look at the below syntax:

**scanf**``(``"%format-specifier"``, &variable)

  • format_specifier: It decides the type of value to be taken as input from the standard input device. Example: “%d” for integer, “%c” for character values, etc.
  • variable: The value taken as input from the user gets stored at the location pointed by the variable.

The scanf() function accepts the value of the specified type through the help of the format specifiers and stores the value at the location pointed by the variable passed as a parameter to it.

Let us now implement the scanf() function through the below examples.

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.
