C语言：
C 语言是一种中间编程语言，由丹尼斯·里奇于 1972 年在贝尔研究实验室开发。 C语言结合了低级和高级语言的特性。因此它考虑了一种中间编程语言。 C 可能是一种高级经典编程语言，允许您开发计算机代码和可移动应用程序。 C语言总共使用了32个关键字。它是开发计算机代码系统的完美语言。
C#语言：
C# 是一种面向对象的编程语言，发音为C-Sharp 。这种语言是由微软在 Anders Heijlberg 和他的团队的领导下开发的，用于与Java竞争。 C# 语言中总共使用了 86 个关键字。在 c# 中，指针仅在不安全模式下使用。
C 和 C# 的区别：
| S.NO | C | C# |
|---|---|---|
| 1. | C language supports procedural programming. | Whereas C# supports object oriented programming. |
| 2. | C language supports pointers. | Whereas in C#, pointers are used only in unsafe mode. |
| 3. | In C language, garbage collection is not. | While in C#, garbage collection is managed by Common Language Runtime (CLR). |
| 4. | C language can be executed cross-platform. | Whereas .NET Framework is required to execute C# language. |
| 5. | By using C language we can achieve low level of abstraction. | Whereas by using the C# we can achieve a high degree of abstraction. |
| 6. | C language is more on functions. | While C# is more on design. |
| 7. | C language gives top notch performance. | While C# gives standard performance. |
| 8. | There are 32 total keywords used in the C language. | While a total of 86 keywords are used in C#. |
| 9. | C language is mainly used in commercial industries and engineering. | Whereas C# is used for software formation and other networking related objective. |
