includestdioh>includeiostreamh>intqq(intx,inty){returnx*y;}voidmain(){intk=7;coutqq(k++,++k)en
main带参数代码示例includeiostreamh>intmain(intargc,char*argv[]){cout输入参数一argv[1]endl;cout输入参数二
includeiostreamh>classanimal{public:animal(){couthellokittyendl;}virtualvoideat(){couteatbianbian
方法：先继承类然后映射函数。includeiostreamh>classanimal{public:animal(charthename);};animal::animal(charthenam
includeiostreamh>classanimal{public:animal(){coutanimalconstructendl;}~animal(){coutconstructanim
