The previous article covered the use of the for loop in detail, but this article also introduces two additional keywords: **break ** and continue, which are usually used with loops;

A for loop can loop 100 times or even 10000 times, and it will always end. If the expression 2 is always true, it will never end. Such as:

for(;;)
Copy the code

The for loop is a perpetual loop that never ends until the seas run dry and the rocks crumble… If we want to solve this awkward problem, we can do it by using the keyword break; Using break in a loop means to terminate the loop immediately.

If the value of I is greater than 10, break the loop and wait for the program to exit…

Using continue in a loop means that the code after the continue will not be executed and the next loop will continue. This can be used as a filter in a loop, for example: 0 to 100, 0, 10 and 90, 99.

If condition 2 is true, the loop continues until the end of the for loop, waiting for the program to exit. If condition 2 is true, the loop continues until the program exits.
