Can the R while Loop be used to create infinite loops?
a) Yes, if the condition is always TRUE
b) No, while loops cannot be infinite
c) Yes, but only with numeric conditions
d) No, while loops always terminate after one iteration
Answer:
a) Yes, if the condition is always TRUE
Explanation:
The while
loop in R can create infinite loops if the condition is always TRUE
. This can happen if the condition never changes within the loop or if it is deliberately set to a constant TRUE
value.
# Example of an infinite loop using while
while (TRUE) {
print("This loop will run forever")
# Use break or some other condition to stop the loop
# break # Uncomment to stop the loop
}
In this example, the loop will continue indefinitely because the condition TRUE
never changes. To prevent infinite loops, it’s important to include a condition or a break
statement that eventually stops the loop.
