请各位学长帮我查一下，万分感谢！

cout<<"\nscore"<<float(numcorrect/numques)*100<<"%"; 这里你打错括号了，应该是cout << "\nscore " << float(numcorrect) / numques*100 << "%"; float应该是强制转换numcorrect才对的。给你改过来了，顺便修改了一下，输入答案正确的显示！号，不正确显示*号
全部代码如下：
#include<iostream>
using namespace std;
void main(void)
{
char key[] = {'a', 'c', 'b', 'c', 'd'};
char c;
int ques = 0, numques = 5, numcorrect = 0;
cout << "Enter the " << numques << " questiontests" << endl;
while (cin.get(c))
{
if (c != '\n')
if (c == key[ques])
{
numcorrect++;
cout << "!";
}
else cout << "*";
else
{
cout
