Since the advent of computers, programmers have been writing codes to automate tasks and make systems more efficient. This has led to an increase in the number of jobs for programmers.

Programmers are responsible for writing codes that will help computer systems perform tasks, such as sending email or updating a database. They might also write code that helps automate other tasks like accounting, payroll management, and billing.

The process of programming can be divided into two main stages: design and development. The design stage is when a programmer creates a plan for the program they want to write and work out how it should work in detail. The development stage is when they actually write the code to make their plan a reality.
