【问题描述】：
我正在写一个刽子手游戏。我无法继续调试，因为我不明白这个错误：
Project4.exe 中 0x00998876 处的第一次机会异常：0xC0000005： 访问冲突写入位置 0x00000000。未处理的异常 Project4.exe中的0x00998876：0xC0000005：访问冲突写入 位置 0x00000000。
这是产生错误的地方：
void Player::getWords()
{
ifstream WordBank;
int index=0;
WordBank.open("C:\\WordBank\\words.txt");
if(WordBank)
{
for(index=0;index<100;index++)
{
WordBank>>Words1[index];
}
WordBank.close();
}
else
{
cout<<"There was an error."<<endl;
}
}
Words 数组被声明为成员变量。
这是我的代码。我还不确定如何格式化单词，我正在尝试完成这个程序。

【问题讨论】：
-
错误告诉你，你正在尝试写入一个为 NULL 的指针。
-
你能出示 Words1 的声明吗？
-
你的调试器没有准确地告诉你哪一行正在通过空指针写入吗？
-
或者 Player 本身是否为 NULL？
-
他正在查看输出窗口而不是调试器。
