What is the name of the part of the parenthesis of a for-loop that terminates the loop?

The part of the parentheses in a for-loop that determines when the loop terminates is called the termination condition or loop condition. This condition is evaluated before each iteration, and if it evaluates to false, the loop stops executing. For example, in a loop structured as for (initialization; condition; increment), the "condition" is the termination condition.
