You come across programming and coding by pursuing computer science engineering. It helps you in making programs ie making systems which will work on programs just by a click of computer. Let's take an example) railway ticket booking.. There are thousands of people who book tickets for a particular train at the same time from different cities of India from different windows, some do it from home too using their computers.  Then have you ever thought how the seats get allotted? Which person gets which seat and why there is no collision.. These all things if done by human can lead to errors and mistakes like 2 people bymistakenly are given the same seat. So this all happens by a single click. And that is through the program that computer software engineers have created. Even machine learning, aritificial intelligence, etc things are learned in this field.
