A compiler is a computer program that transforms code written in a high-level programming language into the machine code. It is a program which translates the human-readable code to a language a computer processor understands binary 1 and 0 bits.

The computer processes the machine code to perform the corresponding tasks.

What is Interpreter?

A compiler should comply with the syntax rule of that programming language in which it is written. However, the compiler is only a program and cannot fix errors found in that program. So, if you make a mistake, you need to make changes in the syntax of your program.

Otherwise, it will not compile. What is Interpreter? An interpreter is a computer program, which coverts each high-level program statement into the machine code.

This includes source code, pre-compiled code, and scripts. Both compiler and interpreters do the same job which is converting higher level programming language to machine code. However, a compiler will convert the code into machine code create an exe before program run. Interpreters convert code into machine code when the program is run. 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 Create the Program No linking of files or machine code generation Source statements executed line by line DURING Execution Advantage The program code is already translated into machine code.

Thus, it code execution time is less. Interpreters are easier to use, especially for beginners. Disadvantage You can't change the program without going back to the source code. Interpreted programs can run on computers that have the corresponding interpreter.

Machine code Store machine language as machine code on the disk Not saving machine code at all. Running time Compiled code run faster Interpreted code run slower Model It is based on language translationlinking-loading model.

It is based on Interpretation Method. Program generation 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.

Execution Program execution is separate from the compilation. It performed only after the entire output program is compiled.

Program Execution is a part ofInterpretation process, so it is performed line by line. Memory requirement Target program executeindependently and do not require the compiler in the memory.

The interpreter exists in the memory during interpretation. Best suited for 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. Code Optimization The compiler sees the entire code upfront.

Hence, they perform lots of optimizations that make code run faster Interpreters see code line by line, and thus optimizations are not as robust as compilers Dynamic Typing Difficult to implement as compilers cannot predict what happens at turn time. Interpreted languages support Dynamic Typing Usage It is best suited for the Production Environment It is best suited for the program and developmentenvironment.

Error execution Compiler displays all errors and warning at the compilation time. Therefore, you can't run the program without fixing errors The interpreter reads a single statement and shows the error if any. You must correct the error to interpret next line.

What is Compiler?

Input It takes an entire program It takes a single line of code. Output Compliers generates intermediate machnie code. Interpreter never generate any intermediate machnie code. Errors Display all errors after, compilation, all at the same time. Displays all errors of each line one by one.

PHP, Perl, Ruby uses an interpreter. Role of Compiler Compliers reads the source code, outputs executable code Translates software written in a higher-level language into instructions that computer can understand. It converts the text that a programmer writes into a format the CPU can understand.

The process of compilation is relatively complicated. It spends a lot of time analyzing and processing the program. The executable result is some form of machine-specific binary code.

Interpret completely translates a program written in a high-level language into machine level language. Interpreter allows evaluation and modification of the program while it is executing.

It makes programming process easy. However, it must be translated into machine language before execution.

This translation process is either conducted by either a compiler or an interpreter. Also known as source code.

Beginner Friendly Tutorials for Programmers

Every computer has its machine language. A machine language programs are made up of series of binary pattern. Machine language programs are executable so that they can be run directly. It is an intermediary code similar to machine code that no processor will understand.

At run time, the object code is converted to the machine code of the underlying platform. Java is both Compiled and Interpreted. To exploit relative advantages of compilers are interpreters some programming language like Java are both compiled and interpreted.

The Java code itself is compiled into Object Code. At run time, the JVM interprets the Object code into machine code of the target computer. Compiled code runs faster while interpreted code runs slower.

Compiler displays all errors after compilation, on the other hand, the Interpreter displays errors of each line one by one. Compiler is based on translation linking-loading model, whereas Interpreter is based on Interpretation Method.

Compiler takes an entire program whereas the Interpreter takes a single line of code. Sublime Text is source code editor majorly used for the MAC platform.
