Program development is the process of creating software applications or systems that meet specific needs. It involves several stages, including planning, designing, coding, testing, and maintaining the program. During this process, developers work closely with stakeholders to understand their requirements and ensure the final product is user-friendly and efficient. In program development, various tools and languages, such as Python, Java, or JavaScript, are used to write the code. Additionally, methodologies like Agile or Waterfall help guide the development process, ensuring that teams can adapt to changes and deliver high-quality software on time.
