Detailed Differences Between C++ and C#

The differences between C++ and C# are as follows:

• Language Type

C++ is a low-level language, while C# is a high-level language.

• Lightweight Language

Compared to C#, C++ is a lightweight language because it requires including C# libraries before compilation, resulting in larger binary files for C#.

• Performance

C++ code runs faster than C# code, providing a better solution for applications requiring higher performance.

• Garbage Collection

C# provides automatic garbage collection, while C++ does not, requiring manual allocation and deallocation of objects.

• Platform Dependency

C# is a standardized language, thus can only run on Windows, while C++ supports all platforms such as Windows, Unix, Linux, Mac, etc.

• Project Types

C++ is mainly used for applications that communicate directly with hardware, while C# is primarily used for mobile, web, desktop, or game applications.

• Compiler Warnings

C++ allows you to execute all operations syntactically correctly, but can sometimes cause actual harm to the operating system. C# is a more protected language, as the compiler issues errors and warnings to prevent serious damage.

• Compilation

C++ code is compiled to machine code, while C# code is compiled to CLR (Common Language Runtime), interpreted by JIT (Just-In-Time compiler).

• Multiple Inheritance

C++ supports multiple inheritance, while C# does not.

• Difficulty Level

C++ contains more complex features than C#, while C# has a simpler hierarchy and is easier to understand.

• Default Access Modifiers

In C++, the default access modifier is public, while in C#, it is private.

• Object-Oriented

C++ is not a purely object-oriented language, whereas C# is a pure object-oriented programming language.

• Boundary Checking

C++ does not support boundary checking for arrays, while C# does.

• ForEach Loop

C++ does not support ForEach loops, while C# does.

• Pointer Usage

In C++, pointers can be used anywhere in the program, while in C#, pointers can only be used in unsafe contexts.

• Switch Statement

In C++, string variables cannot be used in a Switch statement, while in C#, they can.

• Standalone Applications

C++ can be used to develop standalone applications, while C# cannot.
