In which phase of SDLC do you primarily write code?

In the Software Development Life Cycle (SDLC), the phase where code is primarily written is the Implementation phase. During this stage, developers take the designs created in the previous phase and start translating them into executable code. This involves applying programming languages, frameworks, and development tools to bring the application's specifications to life, ensuring that the software functions as intended.

The Implementation phase focuses on actual coding, which includes writing, testing, and integrating the code into the overall system. This is where programmers work collaboratively, often constructing individual components that will later be combined into a complete application. Testing, debugging, and iterative improvements may also occur during this phase to ensure the software meets quality standards and requirements leading up to deployment.
