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.

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.

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.

Why is C called a structured programming language?

C is a structured programming language because it divides a large problem into smaller modules called functions or procedures, each of which handles a specific responsibility. A collection of such functions constitutes the program that solves the entire problem.

In the Question:

C is Called a __________ Language.

The Answer is Structured.

Hence the Option B is Correct.

Structured programming uses three major concepts:

1. Top-down Analysis: Software is always designed to perform some kind of analysis. In the world of software, this type of analysis is referred to as a problem. As a result, we must comprehend how to address the issue. The problem is broken down into small pieces with some significance in top-down analysis. Each problem is solved individually, and the steps to do so are clearly stated.

2. Modular Programming: While programming, the code is broken down into smaller groups of instructions. These groups are referred to as modules, subprograms, or subroutines. Modular programming is based on an understanding of top-down analysis. It discourages program jumps using 'goto statements, which render the program flow untraceable. Jumps are prohibited, and the modular format is encouraged in structured programming.

3. Structured Coding: Structured coding, in contrast to top-down analysis, subdivides modules into smaller units of code in the order of their execution. The control structure is used in structured programming to control the flow of the program, whereas structured coding uses control structure to organise its instructions in definable patterns.

In the Question:

In______________programming, the code is broken down into smaller groups of instructions.

The Answer is Modular Programming.

Hence the Option C is Correct.
