1.编译器:
顾名思义,编译器是用于将代码转换为机器指令的过程。它只是将源代码从高级编程语言转换为低级机器语言。它基本上是一个复杂的软件,可以同时执行代码优化和代码生成。它还使最终代码更有效,并且针对执行时间和存储空间进行了优化。
2.调试器:
顾名思义,调试器是一个用于从代码中删除错误的过程。它仅允许测试和调试其他程序。有时,它还提供两种操作模式,即完全和部分仿真。它用于防止软件或系统的错误操作。它还使用指令集仿真器,而不是直接在处理器上运行程序,以实现对其执行的更高级别的控制。
编译器和调试器之间的区别:

It is a computer program used to translate high-level language into set machine language. | It is a computer program used to test and debug target programs. |
It generally allows computer to run understand program without need of programming software used to create it. | It generally allows you to uncover and diagnose errors in computer software. |
It is very important to convert text that programmer writes into format that CPU understands. | It is very important to provide maximum useful information of data structures and allows easy interpretation. |
It takes less time as compared to debugger. | It takes more time as fixing some errors may introduce others. |
Compiled programs might have some errors or bugs. | Debugged program cannot have any errors. |
It has capability to detect syntax Errors and compile time errors. | It provides more capabilities to detect errors in programs as compared to compiler. |
It generates IL (Intermediate Language) code. | It checks IL code line by line. |
It is more difficult task to design and develop a compiler. | It is less difficult to design and develop a debugger as compared to compiler. |
It performs various tasks such as pre-processing, parsing, semantic analysis, lexical analysis, etc. | It performs various tasks such as check and change data contents, detect and remove existing potential errors, etc. |
