题干中我们需要使得输入为3时,输出为"001",也就是说我们需要进行3次循环,且前两次循环i / j的结果为0,第三次循环i / j的结果为1。 对于选项A,i++表示先使用变量i,然后再让i自增1,所以循环条件将会是i=0, 1, 2,这样前两次循环i / j的结果是0,第三次循环i / j的结果是1,满足我们的需求。
I/O output operations refer to data signals sent by the output device in response to the data input. The data flows from the computer to the output device, where it is extracted and processed. The processing ensures the data output is presented in a manner that users will understand. What ...
BIOS, which stands forBasic Input Output System, is software stored on a small memory chip on themotherboard. It's BIOS that's responsible for thePOSTand therefore makes it the very first software to run when a computer is started. The BIOSfirmwareis non-volatile, meaning that its settings...
An input/output statement or IO statement is a portion of a program that instructs a computer how to read and process data. It pertains to gathering information from an input device, or sending information to an output device.The syntax of the IO statements will be different based on which...
