整理樓上代碼，試運行，結果在最后，沒發現樓主的問題：#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
cout<<"........................."<<endl;
cout << "Hello !" << endl;
cout <<"Welcome to c++!"<<endl;
cout<<"........................."<<endl;
getchar();
cout<<"Which task would you like to do?"<<endl;
cout<<"11"<<endl;
int x;
cin>>x;
switch(x) {
case 1:{
float a=0.00000678f;
double b=0.00000678;
a=a+111111.111f;
b=b+111111.111;
cout<<setiosflags(ios::fixed)<<setprecision(16);
cout<<"a="<<a<<",b="<<b<<endl;
break;
}
case 2:{
cout<<"abc\tde\rf\tg"<<endl;
cout<<"h\ti\b\bjk\n123\'\"\\\x41\102CDE"<<endl;
break;
}
}
return 0;
