The computer teacher has given a task of writing a program to add two numbers using any computer language. Later Rohan used Java to develop the program which consists of 5 lines of code. Java uses compiler to convert the source code to object code. How many times, compilation of Rohan's program will take place?
Answers
Answer:
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). ... So, for a compiled language the conversion from source code to machine executable code takes place before the program is run.
Answer:Computers do not understand human languages. In fact, at the lowest level, computers only understand sequences of numbers that represent operational codes (op codes for short). On the other hand, it would be very difficult for humans to write programs in terms of op codes. Therefore, programming languages were invented to make it easier for humans to write computer programs.
Programming languages are for humans to read and understand. The program (source code) must be translated into machine language so that the computer can execute the program (as the computer only understands machine language). The way that this translation occurs depends on whether the programming language is a compiled language or an interpreted language.
