Object debugging. Class of Char Arrays

I hate giving out my code like this but I'm getting some errors about my UserName class.

Error code is as follows:

    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  

I've tried a number of different ways and this is my final resting place as of now. Any insight or constructive criticism would be much appreciative.

char UserName::getName()

}

Your problem is here:

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

Arrays in C++ cannot be assigned - you need to use strcpy:

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

Better yet, replace all your arrays with std::string.

Edit: And in your class definition:

void setFirstName(char);

should be:

void setFirstName(char[] );
