Types of structured programming

Structured programming can be divided into three categories:

1. Procedural programming: It is a programming paradigm that is based on the idea that programs are sequences of instructions that must be executed. They place a strong emphasis on dividing programs into named sets of instructions known as procedures, which are analogous to functions. A procedure can access and modify global data variables and store local data that is not accessible from outside the procedure's scope. Fortran and ALGOL were two of the first procedural programming languages. The concepts developed in ALGOL are still very relevant and prevalent in modern programming languages.

2. Object-oriented programming (OOP) It defines a program as a collection of objects or resources to which commands are sent. An object-oriented language will create a data resource and pass it to processing commands. For example, a procedural programmer may say "Print(object)," whereas an OOP programmer may say "Tell Object to Print."  

3. Model-based programming: Database query languages are the most common example of this. Units of code in database programming are associated with steps in database access and are updated or run when those steps occur. The structure of the code will be determined by the database and database access structure. Reverse Polish Notation (RPN), a math-problem structure that lends itself to efficient solving of complex expressions, is another example of a model-based structure. Quantum computing, which is still in its early stages, is another example of model-based structured programming; the quantum computer requires a specific model to organise steps, and the language simply provides it.

In the Question:

_______________is a programming paradigm that is based on the idea that programs are sequences of instructions that must be executed.

_____________defines a program as a collection of objects or resources to which commands are sent.

The Answer is Model-based, Object-oriented.

Hence the Option A is Correct.

Structured Programming

Structured programs consist of a structural hierarchy starting with the main process and decomposing downward to lower levels as the logic dictates. These lower structures are the modules of the program, and modules may contain both calls to other lower-level modules and blocks representing structured condition/action combinations. All of this can be combined into a single module or unit of code, or broken down into multiple modules, resident in libraries.

Tabular difference between structured vs unstructured programming:  

 In the Question:

Which of the Following Statement is Incorrect about structured Programming?

(i)It is basically a subset of procedural programs.

(ii)It is Less user-friendly

(iii)It is difficult to learn and follow.

The Answer is Both ii and iii.

Hence the Option A is Correct.

Modules can be classified as procedures or functions. A procedure is a unit of code that performs a specific task, usually referencing a common data structure available to the program at large. Much of the data operated on by procedures is external. A function is a unit of code that operates on specific inputs and returns a result when called.

In the Question:

_____________is a unit of code that performs a specific task, usually referencing a common data structure available to the program at large

___________is a unit of code that operates on specific inputs and returns a result when called.

The Answer is Procedure, Function.

Hence the Option C is Correct.
