Haskell encourages the use of literate programming, where extended text explains the genesis of the code. In literate Haskell scripts (named with the lhs extension), everything is a comment except blocks marked as code. The program can be written in LaTeX, in such case the code environment marks what is code. Also, each active code paragraph ...
Some so-called code "reuse" involves simply copying some or all of the code from an existing program into a new one. While organizations can realize time to market benefits for a new product with this approach, they can subsequently be saddled with many of the same code duplication problems caused by cut and paste programming.
Coding conventions allow programmers to have simple scripts or programs whose job is to process source code for some purpose other than compiling it into an executable. It is common practice to count the software size (Source lines of code) to track current project progress or establish a baseline for future project estimates.
The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code might then be ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
its existing code has become too difficult to handle and extend; the task of debugging it seems too complicated; the programmer finds it difficult to understand its source code; developers learn new techniques or wish to do a big feature overhaul which requires much change; the programming language of the source code has to be changed
The code that a programmer writes should be simple. Complicated logic for achieving a simple thing should be kept to a minimum since the code might be modified by another programmer in the future. The logic one programmer implemented may not make perfect sense to another. So, always keep the code as simple as possible. [21]
Adapt the source of the code generator to the new machine. Execute the adapted source using the interpreter with the code generator source as input. This will generate the machine code for the code generator. The difficult part of coding the optimization routines is done using the high-level language instead of the assembly language of the target.
