Install C on Windows
Step 1: Download Goto http://www.codeblocks.org/downloads. Click "Download the binary release". Select your operating platform (e.g., Windows 2000/XP/Vista/7). Download the installer with GCC Compiler, e.g., codeblocks-13.
For most of you it will be "GNU GCC Compiler". Click on the tab that says "Toolchain executables", then click the button "Auto-detect"....
gcc can actually compile c++ code just fine. The errors you received are linker errors, not compiler errors. which makes it link to the standard c++ library, then it will work just fine.
The steps are:

Compile files
GCC stands for GNU Compiler Collections which is used to compile mainly C and C++ language. It can also be used to compile Objective C and Objective C++.
Compiler Overview Our compiler will follow a three step process that is illustrated above. First, given the inputted source code, it will break the code up into tokens. These are like words and punctuation in English. Second, it will parse the tokens to make sure they are in an order that is allowed in our language.
as long as the compiler does not need to be incredibly efficient than it is not exceedingly difficult. I would say it is far less time consuming than writing an OS. basically you will want to study compilers, but I assume you know that.
LLVM is a compiler and a toolkit for building compilers, which are programs that convert instructions into a form that can be read and executed by a computer. The LLVM project is a collection of modular and reusable compiler and toolchain technologies.
How compilers work. Compilers are utility programs that take your code and transform it into executable machine code files. When you run a compiler on your code, first, the preprocessor reads the source code (the C++ file you just wrote). ... There is a final important step to reach an executable program.
C++ is designed to be a compiled language, meaning that it is generally translated into machine language that can be understood directly by the system, making the generated program highly efficient. For that, a set of tools are needed, known as the development toolchain, whose core are a compiler and its linker.
A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses. ... The object code is machine code that the processor can execute one instruction at a time.
Compilers are divided into three parts 1) Single Pass Compilers 2)Two Pass Compilers, and 3) Multipass Compilers. The "compiler" was word first used in the early 1950s by Grace Murray Hopper. Steps for Language processing system are: Preprocessor, Interpreter, Assembler, Linker/Loader.
The language processor that reads the complete source program written in high level language as a whole in one go and translates it into an equivalent program in machine language is called as a Compiler. Example: C, C++, C#, Java.
Compiler pass are two types: Single Pass Compiler, and Two Pass Compiler or Multi Pass Compiler.
three
Not all compiler systems separate the compiler from the linker -- if it's one program, than it would be OS-specific. ... But the Java compiler (which is written in Java) can run on any machine, and generate code that will run on any machine.
There are two parts to compilation: analysis and synthesis. The analysis part breaks up the source program into constituent pieces and creates an intermediate representation of the source program. The synthesis part constructs the desired target program from the intermediate representation.
The lexical syntax is usually a regular language, with the grammar rules consisting of regular expressions; they define the set of possible character sequences (lexemes) of a token. A lexer recognizes strings, and for each kind of string found the lexical program takes an action, most simply producing a token.
Lexical analysis is the first phase of a compiler. It takes the modified source code from language preprocessors that are written in the form of sentences. The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code.
Reasons for separating lexical analysis from syntax analysis are: ... Portability – Because the lexical analyzer reads input program files and often includes buffering of that input, it is somewhat platform dependent. However, the syntax analyzer can be platform independent.
As the first phase of a compiler, the main task of the lexical analyzer is to read the input characters of the source program, group them into lexemes, and produce as output a sequence of tokens for each lexeme in the source program.
Main Compiler Phases
JavaCC is the standard Java compiler-compiler. Unlike the other tools presented in this chapter, JavaCC is a parser and a scanner (lexer) generator in one. JavaCC takes just one input file (called the grammar file), which is then used to create both classes for lexical analysis, as well as for the parser.
Lexical Analyzer vs. Parser
Question 8 Explanation: Lexical analysis produces a stream of tokens as output, which consists of identifier, keywords,separator,operator, and literals. Consider the following statements related to compiler construction : I. Lexical Analysis is specified by context-free grammars and implemented by pushdown automata.
Count number of tokens : int main() { int a = 10, b = 20; printf("sum is :%d",a+b); return 0; } Answer: Total number of token: 27....Example of tokens:
Issues in Lexical Analysis 1) Simpler design is the most important consideration. The separation of lexical analysis from syntax analysis often allows us to simplify one or the other of these phases. 2) Compiler efficiency is improved. 3) Compiler portability is enhanced.
