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,不一定...
While loop runs until the condition is satisfy and we use while loop when number of iteration are not exactly known to us ,the while loop has initialization. For loop is used when we know the number of iteration,the for loop has all its declaration (initialization,condition,iteration)... ...
For loop: When it is desired to do initialization, condition check and increment/decrement in a single statement of an iterative loop, it is recommended to use 'for' loop.
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. ...
Usually, flowchart loops hold two major types: for loop and while loop. The for loop in the flowchart performs a specific operation until the last element of the criterion is reached. On the other hand, while loop flowcharts operate on conditioning, they execute until a particular condition ...
A for loop is a programming construct that allows a block of code to be executed repeatedly until a certain condition is met.

What is the difference between using for loop and while loop? When to use them? What is the difference between for loops and while loops in c programming? What line of code could be inserted in place of the /// to end the loop immediately and continue the next statement after the loop...
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 ...
