Imagine as you want to go to school from home daily. Your school is 20 kilometres away from your home. What you will do?
Will you go daily to school by walk ? Walking for one day itself is very complex. Then will you walk daily ?
You will go by vehicle or taxi. Right ?. You are transferring the complex work(i.e walking) to the machine which can carry you to school . This will help you to go faster in time, reduce energy consumption of the body, etc.
Programming can reduce the complexity of works and increase efficiency by assigning our work to the machines or computers. Just we have to instruct the machines/computer how to do the work in the way a computer understands. These instructions are known as programs.
