What is difference between String and string in C#

Are you confused about System.String and string in C#? What is the difference between String and string in C#? And how to choose between string and System.String? In this article, I am going to show you all the differences between string and System.String in C## with code examples. .

What is the difference between System.String and string in C#?

Basically, there is no difference between string and String in C#. “string” is just an alias of System.String and both are compiled in the same manner. String stands for System.String and it is a .NET Framework type. “string” is an alias in the C## language for System.String. Both of them are compiled to System.String in IL (Intermediate Language), so there is no difference.

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. 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++.

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.

How to Check String or String View Prefixes and Suffixes in C++20

Up to (and including) C++17 if you wanted to check the start or the end in a string you have to use custom solutions, boost or other third-party libraries. Fortunately, this changes with C++20.

See the article where I’ll show you the new functionalities and discuss a couple of examples.

_This article was originally published at _bfilipek.com.

Intro

Here’s the main proposal that was added into C++20:

C++

std::string/std::string_view .starts_with() and .ends_with() P0457

In the new C++ Standard, we’ll get the following member functions for std::string and std::string_view:

C++

constexpr bool starts_with(string_view sv) const noexcept;

constexpr bool starts_with(CharT c ) const noexcept;

constexpr bool starts_with(const CharT* s ) const;

And also for suffix checking:

C++

constexpr bool ends_with(string_view sv )const noexcept;

constexpr bool ends_with(CharT c ) const noexcept;

constexpr bool ends_with(const CharT* s ) const;

As you can see, they have three overloads: for a string_view, a single character and a string literal.

Simple example:

C++

const std::string url { "https://isocpp.org" };

// string literals

if (url.starts_with("https") && url.ends_with(".org"))

    std::cout << "you're using the correct site!\n";

// a single char:

if (url.starts_with('h') && url.ends_with('g'))

    std::cout << "letters matched!\n";

You can play with this basic example @Wandbox
