C# Types

C## is a strongly typed language. This means that whenever you are dealing with variables you _must _specify what type of variable it is. This post will give you an understanding of types and how we use them in C#.

Have a look at the image below to see the different types which the C## language provides. We’ll cover each type in detail in the following sections.

Value Types

In C## anything that can be assigned a value directly is called a value type. All value type variables store a value _of _that type. For example the below variable x is of the int valuetype. So, the memory allocated to this variable can contain an int value; in this case: 10.

int x = 10

Note: All value types are extended from the .NET **System.ValueType **class.

Simple Types (primitives)

Simple types in C## come built into the language. We call them primitives because they are the lowest level building blocks that make up your C## application. Some of the most used of these types can be summarised in this table.

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.

Maximum Value Of Signed Char in C++

In this article, we will discuss the signed char data type in C++.

Some properties of the signed char data type are:

  • It is generally used to store 8-bit characters.
  • Being a signed data type, it can store positive values as well as negative values.
  • Size of 8 bits is occupied where 1 bit is used to store the sign of the value.
  • A maximum value that can be stored in a signed char data type is typically 127, around 27 – 1 (but is compiler dependent).
  • The maximum and minimum value that can be stored in a signed char is stored as a constant in climits header file and can be named as SCHAR_ MAX and SCHAR_MIN respectively.
  • A minimum value that can be stored in a signed char data type is typically -128, i.e.around –27 (but is compiler dependent).
  • In case of overflow or underflow of data type, the value is wrapped around. For example, if -128 is stored in a signed char data type and 1 is subtracted from it, the value in that variable will become equal to 127. Similarly, in the case of overflow, the value will round back to -128
