程序设计IPO模式: I:Input输入,程序的输入。程序的输入包括:文件输入、网络输入、控制台输入、随机数据输入、程序内部参数输入等。输入是一个程序的开始。 P:Process处理,程序的主要逻辑。程序对输入进行处理,输出产生结果。处理的方法也叫算法,是程序最重要的部分。可以说,算法是一个程序的主要灵魂。 O:Output输出,...
Theinput()function only returns the entire statement of the input in a String format. When programmers call the input() function, it stops the program and waits for the end-user to enter data or information. After inserting the data and pressing enter, the program restarts and returns what ...
