Is a code written in Eiffel programming language compiled or interpreted?
Compiled.
Give a brief description about compiled and interpreted high level languages?
Any high level language may be either compiled or interpreted. The difference is in the execution speed. Interpreted programs must re-learn how to do each statement in the program, whereas a compiled program is already in the machine code language of the hardware and runs much faster.
Which programming language is compiler type and which is interpreter type?
Although most languages are either compiled or interpreted, there's actually nothing to prevent you interpreting a language that is normally compiled, or compiling a language that is normally interpreted. BASIC, for instance, is traditionally an interpreted language, however modern implementations use compilation. Moreover, Java is typical of many modern languages that natively use both techniques by default, compiling the high-level source code into an intermediate byte code which is than interpreted to produce the machine code. But, with a suitable compiler implementation, it is possible to produce native machine code programs from Java source code. When we speak of compiled or interpreted languages we're usually referring to the language's standard, if it has one. C and C++ are standardised and both are compiled, but there's nothing to prevent them from being interpreted. BASIC, on the other hand, is non-standard because it has such a wide-variety of variants, some of which are interpreted, some of which compile to byte code (which is then interpreted) and some of which compile to native machine code. Non-standard languages are generally non-portable therefore you have to look at the specific implementation to determine if it is compiled, interpreted, or both compiled and interpreted.
Is C compiled or interpreted?
Assembler, COBOL, PL/I, C/C++ are all translated by running the source code through a compiler. This results in very efficient code that can be executed any number of times. The overhead for the translation is incurred just once, when the source is compiled; thereafter, it need only be loaded and executed. Interpreted languages, in contrast, must be parsed, interpreted, and executed each time the program is run, thereby greatly adding to the cost of running the program. For this reason, interpreted programs are usually less efficient than compiled programs. Some programming languages, such as REXX™ and Java™, can be either interpreted or compiled.
Is PHP a compiler or interpreter?
It is normally interpreted by another computer program. However subsets of the language can be compiled.
