'''Structured Programming''' is a programming paradigm aimed at improving the clarity, [[Quality|quality]], and development time of a [[Computer Program|computer program]] by making extensive use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines in contrast to using simple tests and jumps such as the go to statement, which can lead to “spaghetti code” that is potentially difficult to follow and maintain.<ref>Definition - What Does Structured Programming Mean?

		+
		+	Structured Programming is a programming paradigm aimed at improving computer programs' clarity, quality, and development time by extensively using subroutines, block structures, for loops, and while loops. Introduced in the late 1960s and early 1970s, particularly through the work of computer scientists like Edsger W. Dijkstra, structured programming advocates for the modular design of programs, where the control flow is structured into blocks that can be easily understood, leading to programs that are easier to write, debug, and maintain.
		+
		+	== Key Principles of Structured Programming ==
		+
		+	*Sequential Execution: The program's execution flows from one statement to the next in a linear sequence.
		+	*Selection: Uses conditional statements (if-then-else) to perform different operations based on conditions.
		+	*Iteration: Employs loops (for, while, do-while) to execute a block of code repeatedly based on a condition.
		+	*Subroutines/Procedures/Functions: Modularizes code into smaller, reusable blocks that can be called from multiple places within a program, reducing redundancy and improving maintainability.
		+
		+	== Advantages of Structured Programming ==
		+
		+	*Improved Readability: Clear, logical structures make programs easier to read and understand.
		+	*Ease of Maintenance: Modular design allows easier updates and modifications without affecting the entire program.
		+	*Reduced Complexity: Breaking down a program into smaller, manageable units helps simplify the development process.
		+	*Enhanced Debugging and Testing: Smaller, independent modules can be tested and debugged in isolation, leading to more reliable code.
		+
		+	== Implementation of Structured Programming ==
		+
		+	Structured programming can be implemented in virtually any programming language. However, it is more naturally suited to those that explicitly support structured control flow constructs like C, Java, Python, and others. The approach revolves around the creation of well-defined functions or procedures and the careful control of program flow using loops and conditional statements, avoiding practices like the use of "goto" statements which can lead to "spaghetti code" - a term for code that is tangled and difficult to follow or maintain.
		+	Examples of Structured Programming
		+
		+	*For Loop: Iterating over a range of values to execute a block of code a specified number of times.
		+
		+	**C Programming Language
		+
		+	for(int i = 0; i < 10; i++) {
		+	*printf("%d\n", i);
		+	}
		+
		+	*If-Then-Else Statement: Making decisions based on conditions.
		+
		+	**Python Programming Language
		+
		+	if condition:
		+	# block of code if condition is true
		+	else:
		+	# block of code if condition is false
		+
		+	Function: A reusable block of code designed to perform a specific task.
		+
		+	**JAVA Programming Language
		+
		+	int add(int a, int b) {
		+	return a + b;
		+	}
		+
		+	== Challenges and Criticisms ==
		+
		+	While structured programming significantly improved software development practices, it is not without its challenges and criticisms. As programs grow in size and complexity, even well-structured code can become difficult to manage without higher-level organizational principles. This limitation led to the development of further paradigms, such as Object-Oriented Programming (OOP), which builds on the ideas of structured programming but adds concepts like encapsulation, inheritance, and polymorphism to manage complexity in large software projects better.
		+	Conclusion
		+
		+	Structured programming is a foundational paradigm in computer science that emphasizes readability, maintainability, and simplicity in program design. Developers can create efficient, reliable, and easy-to-understand software by adhering to its principles. As programming paradigms evolve, the basic principles of structured programming remain integral to effective software development.

		+	== See Also ==
		+	Structured Programming is a programming paradigm that aims to improve the clarity, quality, and development time of a computer program by extensively using subroutines, block structures, for and while loops, and conditional if-else statements. This approach discourages the use of goto statements and other unstructured control flows, promoting instead a logical and hierarchical structure of program construction. Introduced in the late 1960s and early 1970s, structured programming became a foundational concept in software engineering, influencing the development of many programming languages and methodologies.
