E3062 PROGRAMMING 1

Once the program has been written it must be compiled and executed. This is accomplished by an editor and compiler. An editor lets us type a program, makes changes and save it to a file. The compiler then translates the program into a form that the computer can read. Once the program has been compiled and executed the presence of errors will be readily apparent. Syntactic and execution errors usually result in the generation of error when compiling or executing a program. Error of this type is usually quite easy to find and correct. Much more difficult to detect are logical errors since the output resulting from logically incorrect program may appear to be error free. Thus a good bit of probing may be required which is known as logical debugging.
