Abstract

In life, we make a number of decisions at different moments. For example, if it’s raining then we will not play outside; if a customer is susceptible to be churned, then we will use a particular marketing approach, and so on. There are many examples of conditional statements like this. Similarly, in programming, at different instances we have to consider a number of decisions and based on the results, decide the logic/flow of the program. For example, if a username exists and if the password matches, the user will be able to log in; otherwise, they are denied access. If we don’t make these decisions, there can be no notion of intelligence in our programs and thus their usefulness is severely limited.
