CWEB is a computer programming

Computer programming

Computer programming is the process of designing, writing, testing, debugging, and maintaining the source code of computer programs. This source code is written in one or more programming languages. The purpose of programming is to create a program that performs specific operations or exhibits a...

C++

C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...

Java (programming language)

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

Features

• Can enter manual TeX codes as well as automatic.
• Make formatting of C codes for pretty printing.
• Can define sections, and can contain documentation and codes, which can then be included into other sections.
• Write the header codes and main C codes in one file, and can reuse the same sections, and then it can be tangled into multiple files for compiling.
• Include files.
• Change files, which can be automatically merged into the code when compiling/printing.
• Produces index of identifiers and section names in the printout.
