推荐答案
查看给出错误的行的代码。也许，对于初学者（以及其他人的负载）来说这是一个：
Look at your code at the line that gives the error. Probably, it's this one for starters (and loads of others):
examiner(ans1[6],sol1[6]);
然后查看函数的定义：
Then look at the definitions of the function:
void examiner(char x[6],char y[6])其中说它需要两个数组，每个数组包含6个字符;
和参数的定义：
Which says it wants two arrays, each of 6 characters;
And the definitions of the parameters:
char ans1[6],...;
char sol1[6]={'l','i','g','h','t','\0'};
所以ans1是一个包含6个字符的数组，sol1也是如此。
但是你传递给函数的是什么？
ans1 [6] 和 sol1 [6] 这两个都是：
1）单个字符值，而不是数组，而不是实际声明的数组的边界之外的
和
2） - 在C，C＃，C ++中和大多数其他语言一样，数组索引是基于零的，所以一个六字符数组，将有ar [0]，ar [1]，... ar [5]但是没有元素在ar [6]
那么请再想一想你要做的事情，如果你想要传递两个字符或两个数组，那就确定一下 - 并传递正确的数据！
So ans1 is an array of 6 chars, and so is sol1.
But what are you passing to the function?
ans1[6] and sol1[6] both of which are:
1) single character values, not arrays at all
and
2) outside the bounds of the actual declared arrays - in C, C#, C++, and most other languages, the array index is zero based, so a six character array, will have ar[0], ar[1], ... ar[5] but no element at ar[6]
So think again exactly what you are trying to do, and work out if you want to pass two characters, or two arrays - and pass the right data!
