C語言編程題（如果答案對還會加幣）

void main()

{ int i,p;

double m;

char a;

while(a!='n'||a!='N')

{cout<<"請輸入車型"<<endl;

cout<<"1為夏利，2為富康，3為桑塔納"<<endl;

cin>>i;

if(i==1)

{

cout<<"請輸入車程"<<endl;

cin>>p;

if(p<=3)cout<<"車費是7元"<<endl;

if(p>3)

{

m=7+(p-3)*2.1;

cout<<"車費是"<<m<<"元"<<endl;

}

}

if(i==2)

{cout<<"請輸入車程"<<endl;

cout<<"請輸入車程"<<endl;

cin>>p;

if(p<=3)cout<<"車費是8元"<<endl;

if(p>3)

{

m=8+(p-3)*2.4;

cout<<"車費是"<<m<<"元"<<endl;

}

}

if(i==3)

{cout<<"請輸入車程"<<endl;

cout<<"請輸入車程"<<endl;

cin>>p;

if(p<=3)cout<<"車費是9元"<<endl;

if(p>3)

{

m=9+(p-3)*2.7;

cout<<"車費是"<<m<<"元"<<endl;

}

}

cout<<"是否繼續?輸入n結束，輸入其他則繼續"<<endl;

cin>>a;

if(a=='n'||a=='N')break;

}

}

用C++寫的，想轉換為C語言修改頭文件和輸入輸出語句即可！
