I am confused about the use of break and continue. If I want to perform an iteration but stop when a specified condition is met and then continue with the next iteration, do I use break or continue?

In programming, break and continue are used to control the flow of loops.

1. break: This statement is used when you want to terminate the loop entirely without checking the test expression again. When a break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop.

For example:

for i in range(1, 11):
    if i == 5:
        break
    print(i)

In this example, the loop will print numbers from 1 to 4. When i becomes 5, the break statement is encountered and the loop is terminated.

2. continue: This statement is used when you want to skip the rest of the loop for the current iteration and continue with the next iteration of the loop. It does not terminate the loop; instead, it just skips the current iteration and the loop continues with the next iteration.

For example:

for i in range(1, 11):
    if i == 5:
        continue
    print(i)

In this example, the loop will print numbers from 1 to 10, but not 5. When i is 5, the continue statement is encountered and the rest of the loop for the current iteration (i.e., the print statement) is skipped. The loop then continues with the next iteration (i.e., i becomes 6).

So, if you want to stop the loop when a specified condition is met and then continue with the next iteration, you should use continue, not break.
