10 Most Commonly asked Questions about the Compilers

Follow by Email

1.Is C Compiler Written in Assembly

The first C compiler wasn’t written in C, usually when writing a compilers we use either assembly language, or another programming languages, and it’s common that after first compilation, the compiler is rewritten in it’s native language

2.What is the BootStrappnig of the Compiler

Bootstrapping (compilers) … In computer science, bootstrapping is the process of writing a compilers (or assembler) in the source programming language that it intends to compile. Applying this technique leads to a self-hosting compilers.

3.What kind of Programming Language is C

C (programming language) is a general-purposes, imperative computer programming language, supporting structured programming, lexical variables scope and recursion, while a static type system prevents many unintended operation.

4.What are Device Drivers which language is used to write them

It is usually easiest to write them in the same language the OS was written in. Most of device driver are written using system level programming language like C. First and foremost C Compiler is light weight compilers, which is easy to port even on devices with less memory.

5.Who Wrote the first Compiler

The first compiler was written by Grace Hopper, in 1952, for the A-0 System language. The term compiler was coined by Hopper. The A-0 functioned more as a loader or linker than the modern notion of a compiler.

6.Can a Compiler Compile itself

You use the former compiler to compiles the new compilers, and then the new compiler can compile itself. The compiler which can compilers its own sources is called self-hosting compiler. Early compilers were written in another language. For example, first C compiler was probably written in assembler.

7.What is the use of Compiler in java

A Java compiler is a compiler for the programming language Java. The most common form of output from a Java compiler is Java class files containing platform-neutral Java bytecode, but there are also compilers that emit optimized native machine code for a particular hardware/operating system combination.

8.Is JVM Compiler or Interpreter

It is a little of both, but neither in the traditional sense. Modern JVMs take bytecode and compile it into native code when first needed. “JIT” in this context stands for “just in time.” It acts as an interpreter from the outside, but really behind the scenes, it is compiling into machine code

9.What is Compile Time

Compile time refers to the time duration during which the statements written in any programming language are checked for errors. The operations performed at compile time usually include syntax analysis, various kinds of semantic analysis (e.g., type checks and instantiation of the template) and code generation.

10.What is Execution Time

In computer science, runtime, runtime or execution time is the time during which a program is running (executing), in contrast to other program lifecycle phases such as compile time, link time and load time.
