程序设计answer输出一个字符串

1、Exercise 1.1Output a string输出一个字符串Output the string givenhe following.his exercise, you are required to output spel characters,including and .Please add comments in your program输出下面给出的字符串.这题需要你掌握如何输出特殊字符，如和.whereappropriate.请在程序中适当的地方添加注释.EXnLE OUTPUT主程序1 #include source 程序文本框测试数据保存和测试测试输出Exercise 1

4、在它的#includeThere are two types of exercise:am conthe #include source line. the complete programit isplete wiyou needprogram,to provide the exact in order to completemissing par the main protputcorrectly.共有两类练习题：在第一类中，主程序只包含一行:能产生正确输出的整个程序。在第二类中，主程序中包含程#include source行。这种掉，这部程序中缺少的部分所在位置由#include sou

5、rce行所表示。这种情况下，你要给出分，以使得主程序完整并能正确地输出。This exercise belongs to the second ty write something to complete theto write an evaluation s anired to ou need这个练习题属于第二类：你需要写一些东西来是使主程序完整。具体来说，你需要写一个赋值来使一个名为age的整数变量的值增加10。 EX10EX20LE OUTPUT主程序 1 #include 2 using namespatd; 34main() 6cin age; 78#include source 9
