Final answer:
A conditional loop, such as a while loop or a for loop, may not execute the loop body if the initial condition is false. Examples include while loops with false conditions from the outset and for loops initiated with a range of 0.
Step-by-step explanation:
In a conditional loop, it is possible for the loop body to never be executed. Specifically, this is true for a while loop or a for loop depending on the language and the condition given. In a while loop, the condition is evaluated before the loop body is executed. If the condition is false at the outset, the body of the loop will not run even once. Similarly, a for loop can have a condition that is false from the beginning, preventing the loop body from executing.
For example, in a programming language like Python:
while condition:
# Loop body
If condition is false initially, the loop body will not be executed. The same is true for a for loop with a condition that fails from the start:
for i in range(0):
# Loop body
The range function is set to 0, so there's no iteration and the loop body is skipped.
