好象第二题很多人选错啊。呵呵。应该是6/(6+18)
另外这道题有点问题
According to the following code, what is the value of the function’s result?
int t(int a)
{
int s=0;
for (int i=1;i<=a,i++)
{
s=s+1;
}
}
when executing the t(10),what result will you get?

没有返回啊。所以随便选了那个起码还有点像的。难道有什么蹊跷?

varA||varB&varC==varD

A:((varA||varB)&varC)==varD; B:varA||(varB&(varC==varD)); C:(varA||varB)&var(C==varD); D:(varA||varB)&(varC)==varD;

B

8)执行以下操作后a的值为多少?
a=a+b
b=a-b
a=a-b

A:a; B:b; C:a-b; D:a+b;
B


9)The following function is meant to reverse the numbers in an array of 7 integers, but may have a bug.Where is the error,if any?(Mark it with circle)

hi=6-IO; //Line 2
int swap=A[hi]; //Line 3
A[hi]=A[IO]; //Line 4
A[IO]=swap; //Line 5
IO=IO+1; //Line 6
}
}

A:Line 1; B:Line 2; C:Line 3; D:Line 4; E:Line 5; F:Line 6;
不会
