标题: C++求助!!!急！！！！
我有一个assignment是用C++ 来做一个auto billing system
“press any key for next payment" / " press enter for next payment" 的 code要怎样打什么？

作者: 小暗 时间: 2013-3-27 03:53 PM
我是学C的~.~虽然不知道怎么打~不过你可以试看看这个logic~
我试看看用C++~
char ans;
do
{
//your Bill System
cout<< "Do you want to continue the next Bill (Y/N)?\n";
cin >> ans;
}
while((ans !='Y')&&(ans !='y'));

如果你是不要问user的话~那么你就用for loop
for(int i =0;i<9999;i++){
//your Bill System
}
如果你是他按enter才跑去下一个的话~就放 sleep还是什么了~忘记了~

用for loop然后你最后加这个
system("pause");
他就会让user按了enter 才继续xD

事么==~
那么你就用咯~吓一吓他~extra的东西会有分数的xD~
用法你看我刚才那个~~
do{

}while()

这个东西的意识就是先作~然后当发生什么事情~就在做多一次~
你问user要不要continues会比较好~试看看xD~
