Final answer:
The code snippet 'for (;;) cout << "wow";' represents an infinite loop as it lacks termination conditions and will keep executing indefinitely.
Step-by-step explanation:
The for (;;) cout << "wow"; is an example of an infinite loop. This loop will continue to execute indefinitely because it lacks a loop control statement that would ordinarily cause the loop to terminate. In C++ and many other programming languages, omitting the control statements (initialization, condition, and increment/decrement) creates a loop that has no end condition, causing it to run forever unless externally interrupted.
