What is Structure Programming

There are many Programming paradigms we use in programming languages, and the Programming paradigm deals with how the problem will be solved using a programming language. A Programming language can consist of more than one programming paradigm which makes it more efficient. The programming paradigm also controls the flow of program execution, and here in this article, we have explained what is Structured Programming and what are its advantages and Disadvantages.

What is Structured Programming?

Structured programming is similar to Procedural programming you can also say it is a subset of Procedural programming. It is used to improve the quality, and clarity of the programming language so the execution of the program becomes more logical and readable.


By its name you might have noticed that the programming languages which support structured programming use structured control flow which involves selection, iteration, subroutines, and sequence blocks structure and the code of that programming language executed according to the structure in which it has written.

Like Procedural Programming, the structured programming also follows the approach of top to bottom, this means the code written in Structured programming executes one after other in sequential order from top to bottom.

Structured Control

Structure programming involves some elements which are Sequence, Iteration, Selection, and Subroutines.

1. Sequence

In structured programming, the code is written in sequential order so the program can follow the approach of top to bottom. The sequence of the program also increases the readability, so a human can read the code and can tell what that program supposed to do.

 2. Selection

Structured Programming also consists of a Selection block such as if…else statements, where the execution of the next code depends upon the selection statement.

3. Iteration

In iteration, we can repeatedly execute a block of code again and again with the help of loop statements. We can control how many times we want to execute the same block of code.

4. Subroutines

Subroutines are the functions, methods, procedures or subprograms which termed as a single block of code.

Advantages & Disadvantages of Structured Programming


  • It is easy to understand.
  • It consists statement of English vocabulary
  • Need less time to write code.
  • Easier to maintain
  • Can be debugged Easily
  • Most of the high-level programming language support this paradigm
  • It is machine independent, which means the Structured programming written in one computer can be run on any other computer.


  • It is a machine-independent so we need a translator to convert it into machine language.
  • The program depends upon changeable factors like data-types. Therefore, it needs to be updated with the need on the go.
