COMPILER
·
A compiler is used to convert a program written in some high
language into a target machine understandable language. This conversion is done
in one step and reports all the errors of the program at the end. In case an
error(s) is found, it is rectified and recompiled. Interestingly, the program
compilation process continues till the last statement of the program and after
that all the errors are removed (or repaired). It is very important to notify
that compilers are large programs which reside permanently on secondary storage
and when translation of program is to be done, they are copied into the main
memory of computer. The programmer can copy the executable object code onto any
other similar machine and run the program without compiling it again.
