IF-THEN statement

In computer science, an if-then statement is a fundamental control structure that allows a program to make decisions and execute different paths of code based on whether a condition is true or false. It's a core concept in programming, enabling conditional execution.1

The basic structure is: IF a certain condition is met, THEN execute a specific block of code. This allows programs to respond dynamically to varying circumstances, a key aspect of machine programming and automation. For example, a program might check if a variable's value is greater than zero; if it is, it proceeds with a calculation. This conditional logic is essential for error detection, safety monitoring, and optimizing processes.12
