TRANSLATORS

There are 3 types of translators available for the languages

1. Assembler :This translator is used to convert the programs written in low level language in to Machine language.
2. Compiler:It is used to convert high level language to Machine level language. It checks for errors in the entire program and converts the program in to Machine language.
   C Uses Compiler As Translator
3. Interpreter:It is used to convert high level language program into machine level language. It checks for error statements by statement and converts the statement into machine language.

Various steps involved in executing a C program:

1. Creating a C program.
2. Compiling a C program.
3. Linking the program with functions that are needed from C library.
4. Executing the program.
