问题第三部分:(问答)
1请简要说明如何测试下面的程序？
template<class T>
void OutputRoots(T a, T b , T c)
{
T d=b * b - 4*a*c;
if(d>0)
{
float sqrtd=sqrt(d);
count <<”there are two real roots”
<<(-b+sqrtd)/(2*a)
<<”and”
<<(-b-sqrtd)/(2*a)
<<endl ;
}
}
Else if (d= =0) {
Cout<<”there is only one distinct root”
<<-b(2*a)
<<endl;
}
else{
cout <<”The roots are complex”
<<endl
<<”The real part is”
<<-b/(2*a)
<<”The imaginary part is”
<<sqrt (-d)/ (2*a)
<<endl;
}
2、以下是一段用C编写的函数,请指出其中存在的问题:
1 int PtintDigit(void)
2 {
3 char*p;
4 int i=0;
5 p=(char*) malloc (256*sizeof (char));
6 for (I=0;I<=256;I++,p++)*p=I;
7 printf(Here is the numbers you need; %d\n”,i)
8 }
问题第四部分(外语考察)
请翻译下面这段文字,中文写在后面:
For Chinese applicants,the first step in applying for a visa is to make an appointment by calling 65325305 or 65322228. The problem is that the two numbers are so busy that often they can’t get through . Mr Bennet explained :“Since all embassies have to use 6532 telephone prefix and the number of lines is limited, the US embassy is only allotted two lines for our appointment system. Insgroupsto solve the problem, we plan to work through a contractor. Contractors don’t
have to use the 6532 prefix , so they can be assigned move lines and hire lots of people to answer calls . Applicants will also be able to use faxes and the Internet to make appointments, which will greatly enhance flexibility and convenience, Since the contact has not been awarded yet , I can’t say exactly when the new system will be operative-hopefully sometimes in the fall.”。
