使用cstring数组有问题

我有麻烦与我的代码与数组的东西。我得到以下错误

In function ‘int main(int, const char**)’:
75: error: cannot convert ‘char*’ to ‘char (*)[81]’ for argument ‘1’                                                                  ion(char (*)[81], OneItem*, int&, int&)’
 In function ‘void parseInformation(char (*)[81], OneItem*, int&, in
164: error: ISO C++ forbids comparison between pointer and integer
166: error: incompatible types in assignment of ‘const char [2]’ to
169: error: ISO C++ forbids comparison between pointer and integer
174: error: ISO C++ forbids comparison between pointer and integer
174: error: ISO C++ forbids comparison between pointer and integer
176: error: invalid conversion from ‘char*’ to ‘char’

代码与行号不对齐。我已经尝试了很多东西谷歌一些东西仍然没有找到解决方案。

const int MAX_CHARACTERS = 80;
