Compile will parse or analyses all of the language statements for its correctness. If incorrect, throws an error If no error, the compiler will convert source code to machine code. It links different code files into a runnable program know as exe Run the Program.

Generates output program in the form of exe which can be run independently from the original program.

Do not generate output program. So they evaluate the source program at every time during execution. Program execution is separate from the compilation.

It performed only after the entire output program is compiled. Bounded to the specific target machine and cannot be ported. For web environments, where load times are important. Due to all the exhaustive analysis is done, compiles take relatively larger time to compile even small code that may not be run multiple times.

In such cases, interpreters are better. The compiler sees the entire code upfront. Hence, they perform lots of optimizations that make code run faster. Compiler displays all errors and warning at the compilation time. Speed Comparatively faster Slower Memory Memory requirement is more due to the creation of object code. It requires less memory as it does not create intermediate object code. Errors Display all errors after compilation, all at the same time.

Displays error of each line one by one. A compiler is a program that reads a program written in the high-level language and converts it into the machine or low-level language and reports the errors present in the program. It converts the entire source code in one go or could take multiple passes to do so, but at last, the user gets the compiled code which is ready to execute.

The symbol table is somewhat a data structure which manages the identifiers along with the relevant type of data it is storing. Error Handler detect, report, correct the errors encountering in between the different phases of a compiler. The interpreter is an alternative for implementing a programming language and does the same work as a compiler. Interpreter performs lexing , parsing and type checking similar to a compiler.

But interpreter processes syntax tree directly to access expressions and execute statement rather than generating code from the syntax tree. An interpreter may require processing the same syntax tree more than once that is the reason why interpretation is comparatively slower than executing the compiled program. Compilation and interpretation probably combined to implement a programming language.

In which a compiler generates intermediate-level code then the code is interpreted rather than compiled to machine code. Employing an interpreter is advantageous during program development, where the most important part is to be able to test a program modification rapidly rather than run the program efficiently. Compiler and interpreter both are intended to do the same work but differ in operating procedure, Compiler takes source code in an aggregated way whereas Interpreter takes constituent parts of source code, i.

Although both compiler and interpreter have certain advantages and disadvantages like Interpreted languages are considered as cross-platform, i. Compiled languages are faster regarding the compilation process.

A cross-compiler running on a Windows machine, for instance, could generate code that runs on a specific Windows operating system or a Linux operating system platform. Source-to-source compilers translate one program, or code, to another of a different language e.

Choosing a compiler then, means that first you need to know the ISA, operating system, and the programming language that you plan to use. Compilers often come as a package with other tools, and each processor manufacturer will have at least one compiler or a package of software development tools that includes a compiler. Often the software tools including compiler are free; after all, a CPU is completely useless without software to run on it.

Compilers will report errors after compiling has finished. Interpreters Another way to get code to run on your processor is to use an interpreter, which is not the same as a compiler. An interpreter translates code like a compiler but reads the code and immediately executes on that code, and therefore is initially faster than a compiler. Thus, interpreters are often used in software development tools as debugging tools, as they can execute a single in of code at a time.

Compilers translate code all at once and the processor then executes upon the machine language that the compiler produced. If changes are made to the code after compilation, the changed code will need to be compiled and added to the compiled code or perhaps the entire program will need to be re-compiled.

There are several types of interpreters: the syntax-directed interpreter i.
