While writing a program, there may be a situation when you need to adopt one out of a given set of paths. In such cases, you need to use conditional statements that allow your program to make correct decisions and perform right actions.

Solidity supports conditional statements which are used to perform different actions based on different conditions. Here we will explain the if..else statement.

The following flow chart shows how the if-else statement works.
