C++ 对象调试。一类字符数组

我讨厌像这样给出我的代码，但是我的UserName类出现了一些错误

错误代码如下：

    232 prototype for `void UserName::setFirstName(char*)' does not match any in class `UserName'

    23 void UserName::setFirstName(char) 

    In member function `void UserName::setFirstName(char*)': 

    233 invalid conversion from `char*' to `char' 

    233 At global scope: 

    235 prototype for `void UserName::setLastName(char*)' does not match any in class `UserName
24 void UserName::setLastName(char) 
[Build Error]  [journey.o] Error 1  

我已经尝试了很多不同的方法，这是我现在最后的安息之地。任何见解或建设性的批评都将不胜感激

char UserName::getName()
{
     fullName[57] = firstName[26] + lastName[31]; 
     return fullName[57];
}

你的问题是：

void UserName::setFirstName(char fn[26]){
     firstName[26] = fn; 
}

C++中的数组不能被赋值，需要使用Struc::/P>

void UserName::setFirstName(char fn[]){
     strcpy( firstName, fn ); 
}

更好的是，用std:：string替换所有数组

编辑：在类定义中：

void setFirstName(char);

应该是：

void setFirstName(char[] );

我的意思是在最后把它们加在一起，而不是打印fn+ln@Casey抱歉-我不明白。我会完全使用strcpy，但我正在尝试合并许多不同的方法，所以我不想使用它来组合两个stringsprotype for void UserName:：setFirstNamechar*'与任何类内UserName'void不匹配用户名：：setFirstNamechar@Casey你是否也不愿意使用+来添加两个整数？如果你对C++学习很认真，使用STD::String来表示字符串，而不是char *。string有一个方便的赋值运算符，可以省去strcpy的麻烦。你能给我举个例子吗？
