In most programming languages, you'll come across three main types of loops: the "for" loop, the "while" loop, and the "do-while" loop. What's a "for" loop? A "for" loop is often used when you know the number of times you want to repeat a certain block of code. You specify...
Do-While Loop: The do-while loop is similar to the while loop but with one crucial difference: the condition is checked after the loop body is executed. This guarantees that the loop body is executed at least once. For Loop: The for loop is used when you know the exact number of iter...
What is the difference between a while loop and a do-while loop? Explain when to use "for loop" and the "while loop". What is an infinite loop? What are limitations when using a for loop? How to use a for loop What is the advantage of using a do-while loop over a while loop?
How does the "while" loop work? The "while" loop is another type of loop used for iteration. It repeatedly executes a code block if a specified condition remains true. The condition is evaluated before each iteration, and if it becomes false, the loop terminates. ...

除了for loop ,上面的例子我們也可改用 while loop 來做到: num=1 while [ "$num" -le 10 ]; do echo "num is $num" num=$(($num + 1)) done 复制代码 while loop 的原理與 for loop 稍有不同: 它不是逐次處理清單中的變量值,而是取決於 while 後面的命令行之 return value : ...
