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.
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 global behaviour and used variables to pass information in and out of subroutines.
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.
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.
It teaches fundamental principles of computer programming, including recursion, abstraction, modularity, and programming language design and implementation. MIT Press published the first edition in 1984, and the second edition in 1996. It was formerly used as the textbook for MIT's introductory course in computer science.
A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. A programming language can be classified as supporting one or more paradigms. [1] Paradigms are separated along and described by different dimensions of programming.
In structured programming, the ordered sequencing of successive commands is considered one of the basic control structures, which is used as a building block for programs alongside iteration, recursion and choice.
BASIC (Beginners' All-purpose Symbolic Instruction Code) [1] is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963.
