1.编译器:
它是一个翻译器,它接受输入,即高级语言,并产生低级语言,即机器或汇编语言的输出。
- 编译器比汇编器更智能,它会检查各种限制、范围、错误等。
- 但其程序运行时间较多,占用内存较大。它的速度很慢,因为编译器会遍历整个程序,然后将整个程序翻译成机器码。

2.翻译:
解释器是将编程语言翻译成可理解语言的程序。 ——
- 它一次只翻译一个程序语句。
- 解释器通常比编译器小。

让我们看看编译器和解释器之间的区别:
S.No. | Compiler | Interpreter |
---|---|---|
1. | Compiler scans the whole program in one go. | Translates program one statement at a time. |
2. | As it scans the code in one go, the errors (if any) are shown at the end together. | Considering it scans code one line at a time, errors are shown line by line. |
3. | Main advantage of compilers is it’s execution time. | Due to interpreters being slow in executing the object code, it is preferred less. |
4. | It converts the source code into object code. | It does not convert source code into object code instead it scans it line by line |
5 | It does not require source code for later execution. | It requires source code for later execution. |
Eg. | C, C++, C# etc. | Python, Ruby, Perl, SNOBOL, MATLAB, etc. |
