The "if-else" statement is a fundamental programming concept used to make decisions in code. It allows a program to execute certain actions based on whether a specific condition is true or false. For example, if a variable temperature is above 30 degrees, the program can display "It's hot outside." If the condition is false, it can execute an alternative action, such as displaying "It's a pleasant day."
This structure helps in controlling the flow of a program, making it more dynamic and responsive. By using "if-else," programmers can create more complex logic, allowing for better user interactions and decision-making processes within applications.
