一、How to stop while loop

In programming, while loop is a common control structure, and its operation depends on the conditions in the loop body. To stop the while loop, there are three main methods:

0, the loop will automatically end. At this time, because the condition is not established, the while loop will automatically exit.

2. Use the break statement in the loop body to force termination. For example, in the while(1) loop, if a certain condition b5 is detected, a break statement can be inserted to make the program jump directly out of the loop body.

3. When certain conditions are met, the function execution ends through the return statement and the while loop is indirectly exited. For example, while(1){if(c8)return(XXX);}, when c8 is true, the program will execute the return statement and return to the pre vious function.

It should be noted that the syntax of while loop may be different in different programming languages. For example, in C language, use do- while or while(condition) statement, but in Java it is written While(condition){statement;}. Although the syntax varies, the core principle is that the loop stops when the condition no longer holds or when a specific exit condition is encountered.

In a loop, sometimes we may also use the continue statement to skip the remaining part of the current loop and directly enter the next round of loop. The break statement will directly terminate the entire loop and no longer execute the subsequent loop body code.

In short, by adjusting loop conditions, using break or return statements, and using continue, we can effectively control the execution and stopping of while loops.
