A "running loop" is a programming construct that repeatedly executes a block of code as long as a specified condition is true. It allows developers to automate tasks, process data, or perform actions multiple times without needing to write the same code repeatedly. Common types of loops include the for loop, while loop, and do-while loop. In a running loop, the condition is checked before or after each iteration, depending on the loop type. If the condition evaluates to true, the code inside the loop runs again. This process continues until the condition becomes false, at which point the loop terminates.
