1、16章部分选做习题16.1编写一个模板返回形参的绝对值，至少用三种不同类型的值调用模板。注意：在16.3节讨论编译器怎样处理模板实例化之前，你应该将每个模板定义和该模板的所有使用放在同一文件中。//16.1_template.cpp:定义控制台应用程序的入口点。//#include"stdafx.h"#includetemplateinlineTabs(TtVal){returntVal>0?tVal:-1*tVal;}int_tmain(intargc,_TCHAR*argv[]){std::cout<<"

2、tabs(false)is:t"<

3、。//#include"stdafx.h"#include#include#include#include#includeusingnamespacestd;templateinlinevoidtestOstream(ostream&os,TtVal){os<

4、eam(cout,6);cout<<"TestoftestOstream(cout,true):t";testOstream(cout,true);cout<<"TestoftestOstream(cout,8.6):t";testOstream(cout,8.6);cout<<"TestoftestOstream(cout,"Good!"):t";testOstream(cout,"Good!");cout<

5、m.txt");assert(outfile);if(!outfile){returnNULL;}cout<<"tTestofofstream,Pleasecheckthefilejustcreate.";testOstream(outfile,"TestoftestOstream(outfile,6):t");testOstream(outfile,6);testOstream(outfile,"TestoftestOstream(outfile,true):t");testOstream(outfile,true);test

6、Ostream(outfile,"TestoftestOstream(outfile,8.6):t");testOstream(outfile,8.6);testOstream(outfile,"TestoftestOstream(outfile,"Good!"):t");testOstream(outfile,"Good!");outfile.close();cout<

7、ss,8.6)/(oss,"Good!"):"<

8、e时，传递用字符串字面值初始化的两个string对象。如果编写以下代码会发生什么？compare(“hi”,
