Code templates are pre-defined structures or patterns used in programming to streamline the coding process. They provide a framework that developers can fill in with specific details, reducing the time spent on repetitive tasks. By using code templates, programmers can ensure consistency and maintain best practices across their projects. These templates can be found in various programming languages and are often included in integrated development environments (IDEs) like Visual Studio or Eclipse. They can cover a range of functionalities, from simple functions to complex class structures, making it easier for developers to focus on the unique aspects of their code.
