Structured Programming and Its Impact on Application Efficiency Structured programming is one of the oldest and most important programming paradigms. It is based on dividing programs into clear units using sequence, selection, and iteration. This approach improves code readability and maintainability. Structured programming reduces complexity and minimizes programming errors. It also enhances application performance by organizing execution flow. Programs written in a structured way are easier to test and debug. Many modern programming techniques are built upon this paradigm. Therefore, structured programming plays a vital role in improving application efficiency and reliability.
