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.
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 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.

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. Vim, Sublime 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++.

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:
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.
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.
