Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection and repetition, block structures, and subroutines. It emerged in the late 1950s with the appearance of the ALGOL 58 and ALGOL 60 programming languages, with the latter including support for block structures.

Non-structured programming is the historically earliest programming paradigm capable of creating Turing-complete algorithms .It is often contrasted with the structured programming paradigm, in particular with the use of unstructured control flow using goto statements or equivalent.
Jackson structured programming (JSP) is a method for structured programming based on correspondences between data stream structure and program structure. JSP structures programs and data in terms of sequences, iterations and selections, and as a consequence it is applied when designing a program's detailed control structure.
Structured analysis is part of a series of structured methods that "represent a collection of analysis, design, and programming techniques that were developed in response to the problems facing the software world from the 1960s to the 1980s. In this timeframe most commercial programming was done in Cobol and Fortran, then C and BASIC.
A struct in the C programming language (and many derivatives) is a composite data type (or record) declaration that defines a physically grouped list of variables under one name in a block of memory, allowing the different variables to be accessed via a single pointer or by the struct declared name which returns the same address.
Procedural programming is a programming paradigm, derived from structured programming, based on the concept of the procedure call. Procedures, also known as routines, subroutines, or functions, simply contain a series of computational steps to be carried out. Any given procedure might be called at any point during a program's execution, including by other procedures or itself. The first major procedural programming languages appeared circa 1957–1964, including Fortran, ALGOL, COBOL, PL/I ...
C (/ s iː /, as in the letter c) is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, while a static type system prevents unintended operations.
SQL (/ ˌ ɛ s ˌ k juː ˈ ɛ l / S-Q-L, / ˈ s iː k w əl / "sequel"; Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).
The structured programming concept was formalized in 1966 by Corrado Böhm and Giuseppe Jacopini, who demonstrated theoretical computer program design through loops, sequences and decisions. In the late 1960s-early 1970s, Edsger W.Dijkstra developed structural programming functionality as a widely used method, in which a program is divided into multiple sections with multiple exits and one access point.
Structured programming is the suggested antidote to unstructured programming, which existed for decades before Structured programming was invented. In the beginning, there was UN-structured programming . An unstructured program is a procedural program – the statements are executed in sequence as written.
