A. For loop is used for definite iterations while while loop is for indefinite iterations. B. For loop is faster than while loop. C. While loop can only be used with numbers while for loop can be used with any data type. D. There is no difference. ...
while loop can run indefinitely C. for loop is more complex D. none of the above 相关知识点: 试题来源: 解析 B。本题考查 for 循环和 while 循环的主要区别。while 循环可以根据条件无限运行,而 for 循环通常有明确的循环次数限制。选项 A 不准确,不能说 for 循环总是更快。选项 C 不准确,不...
Which loop should I use? The choice of loop depends on the situation. If you know the exact number of iterations, a "for" loop is often a good choice. If the number of iterations is uncertain and depends on a condition, you can use a "while" or "do-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. ...
What is the advantage of using a do-while loop over a while loop? Explain the difference between while loop and for loop? Give an example for the while loop and the for loop. How do you control a loop? What is the difference between using for loop and while loop? When to use them...
then you redefined "get_fib" inside the function so that it no longer refers to the function and instead refers to an array of double. If you are intending to work recursively then you should not have the loop. If you are intending to not work recursively then you need the output, F,...
we want to protect, area 0 in our case, next we have to configure the priority, there are two options; high and low. When we use the high priority, OSPF treats loopback and /32 prefixes with higher priority. When we choose the low priority, it just calculates an LFA for all ...
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 : * 若為 ture ,則執行 do 與 done 之間的命令,然後重新判斷 while 後的 return ...
Ado loopruns code, then checks for the condition afterward. Ado-while loopis like a while loopbut puts the condition at the end, so that the loop runs at least one time if the condition is not met. A while loop will not run if the condition is not met. ...
🔹 Same output with the first one but different approach 🔹 In this case, the condition is in the while statement, and once i becomes greater or equal to 4, the while loop will stop. For better understanding, I adjusted the value of i so it will be the same for both exam...
