+
+        - **Step 1**: The programmer **analyzes reuqirements** to identify the process to complete the task.
+        - **Step 2**: The programmer **implements** the identified process in programming code as a computer program.
+        - **Step 3**: The programmer **deploys** the program on the computer and let the complete complete the task and give expected outcomes.
+
+        This is a simplified outline of coding (computer programming), and additional steps may be involved depending on the task's complexity and the program.
