Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
As the variable is global, it retains the modified value when it returns to the original code. A key concept of structured programming is the local variable, which holds its value separate from other variables with the same name in other locations in the composite program. As BASIC did not have the concept of scope, many programs relied on the ...
Dartmouth BASIC is the original version of the BASIC programming language.It was designed by two professors at Dartmouth College, John G. Kemeny and Thomas E. Kurtz.With the underlying Dartmouth Time-Sharing System (DTSS), it offered an interactive programming environment to all undergraduates as well as the larger university community.
Dahl and Nygaard were the first to develop the concepts of class, subclass (allowing implicit information hiding), inheritance, dynamic object creation, etc., all important aspects of the OO paradigm. An object is a self-contained component (with a data structure and associated procedures or methods) in a software system. These are combined to ...
Knuth discusses software patenting, structured programming, collaboration and his development of TeX. The oral history discusses the writing of The Art of Computer Programming. "Robert W Floyd, In Memoriam", by Donald E. Knuth, 2003 - (on the influence of Bob Floyd) TAoCP and its Influence of Computer Science (Softpanorama)
JSP is not used to structure programs at the level of classes and objects, although it can helpfully structure control flow within a class's methods. JSP uses a diagramming notation to describe the structure of inputs, outputs and programs, with diagram elements for each of the fundamental component types. A simple operation is drawn as a box.
S-BASIC (for Structured Basic) was a "structured" BASIC variant, distributed with Kaypro CP/M systems. [1] [2] It was made by Topaz Programming is distributed by Micro-Ap (San Ramon, California). [3] SBasic was compatible with the syntax of BASIC, a programming language commonly used in the 1970s through the 1980s, as well as Fortran77.
The textbook An Introduction to Programming: A Structured Approach Using PL/I and PL/C was written by Conway and Gries using PL/C as the programming language and was published in 1973. [14] It presented top-down design, [23] and stressed the discipline of structured programming throughout, becoming one of the most prominent textbooks to do so. [41]
