This is because the looping condition is verified at the top of the loop block in case of while, and since the condition is false, the program doesn't enter the loop.In case of do-while, the program unconditionally enters the loop, increments "b" to 11 and then doesn't repeat as ...
1. What is the primary purpose of the 'DO WHILE' loop in REXX? A. To execute a block of code a fixed number of times B. To iterate over a collection C. To repeat a block of code while a condition is true D. To define a function Show Answer 2. What keyword is used ...
–Awk Do whileloop is called exit controlled loop, whereas awk while loop is called as entry controlled loop. Because while loop checks the condition first, then it decides to execute the body or not. But theawk do whileloop executes the body once, then repeats the body as long as the ...

If d_lookup finds that a rename happened while it unsuccessfully scanned a chain in the hash table, it simply tries again. 名称查找过程(d_lookup())不会尝试阻止这种情况发生,而只是检测它何时发生。rename_lock是一个序列锁,每当重命名任何dentry时都会更新它。如果d_lookup发现在无法成功扫描哈希表中的...

shell是一个解释器,为了解释Unix命令,目的就是交互,因为shell就是为了实现Unix命令的思想来引入的;shell命令就是Unix系统命令;shell同时又是一种编程语言,如提供了变量定义、控制结构等。所以shell包含了unix系统命令、系统命令解释器和编程语言三个部分。 shell是一种泛称。Bash shell是shell的一种具体实现,它实现了...
