我是用VC写的，代码如下：#include<iostream>using namespace std;void ComputeRed(double addNow,double surveyNow,double surveyInZero){ double result=0; try { result=surveyNow/(addNow+surveyInZero)*100; cout<<addNow<<" "<<surveyNow<<" "<<result<<endl; } catch(...) { cout<<"输入有误！"<<endl; }}void main(){ double surveyInZeroForRed=0; double surveyInZeroForWhite=0; double addNow=0; double surveyNow=0; int i=0; cout<<"请输入标液加入量为0的测量值(红酒):"; cin>>surveyInZeroForRed; cout<<"请输入标液加入量为0的测量值(白酒):"; cin>>surveyInZeroForWhite; while(1) { cout<<"请输入测试酒类型(0为红酒，1为白酒)："; cin>>i; cout<<"请输入标液加入量："; cin>>addNow; cout<<"请输入标液测量值："; cin>>surveyNow; if(i) { cout<<"白酒："; ComputeRed(addNow,surveyNow,surveyInZeroForWhite); } else { cout<<"红酒："; ComputeRed(addNow,surveyNow,surveyInZeroForRed); } cout<<"是否退出？(0为继续，1为退出)："; cin>>i; if(i) break; }}
