What does a compiler read?

A compiler converts source code (which you’ve written) to an object code the machine can read. This machine-readable code is usually made up of zeroes and ones since it’s in binary form.

What are strings in compiler?

Definition: A string over an alphabet is a finite sequence of symbols from that alphabet. Strings are often called words or sentences.

What does a compiler output?

The compiler takes input data sets and libraries and produces various types of output, including object code, listings, and messages. The compiler also uses utility data sets during compilation.

What are tokens in compiler?

A token is a pair consisting of a token name and an optional attribute value. The token name is an abstract symbol representing a kind of lexical unit, e.g., a particular keyword, or sequence of input characters denoting an identifier. The token names are the input symbols that the parser processes. Pattern pg. 111.

What is regular in compiler?

A regular expression is a set of patterns that can match a character or string. It can also match alternative characters or strings. The grammar defined by the regular expression is known as regular grammar, and the language is known as regular language.

Does compiler generate object code?

The compiler produces an intermediary form called object code. Object code is often the same as or similar to a computer’s machine language. The final step in producing an executable program is to transform the object code into machine language, if it is not already in this form.

Where does a compiler run?

compilers/assemblers are themselves software, and reside wherever they were installed on the computer. that also implies that you can have as many/few of each as you want. no, it doesn’t. e.g. you can trivially compile/assemble code for an ARM cpu running Android while working away on an Intel x86 cpu running Windows.
