invalid conversion from `char' to `const char*

I'm writing a programm in C++ that mimics a database, and this problem keeps comming up, and I can't seem to get rid of it. I placed a comment above the line where the problem is. And sorry its so long!

Code:

#include <iostream>



#include <cstring>



#include <fstream>



#include <string>            



#include <stdio.h>



#include <iomanip>







using namespace std;







struct Score



{                  // making record fields



    char student[50];



    char studentscore[50];



    char student_name;



    int how_many;



};

.

.

.



// Add score function



void add_Score(int&, Score [])







{



        //declareing local varables that are needed







        char score[50];



        char studentscore[50] ;



        char student_name;



        int student_score ;



        int how_many;



        int new_score;



        int i = -1 ;



        int num_students;



        char choice = 'Y' ;



        Score The_Scores[50];







        cout << "You selected 'Add a score' to the list." << endl ;



        cout << endl ;







        // user enters a score which is stored in score[20])



        cout << "\t"<< "1) Enter the score (up to 3 characters) " 



                    << endl << "\t" << ": " ;







    fflush(stdin);



        gets(score) ;







//searches for the student name the user enters

//the following line is where the problem is 

        while (strcmp(score,  The_Scores[i].student_name)!=0 && i <=num_students)



                i++ ;







//if the student name was not found



        if (strcmp(score, The_Scores[i].student_name)!=0)



        {



                cout << "The student name was not found and will be added to the list." << endl ;



                



                cout << "\n\t" << "2) Please, enter the student's last name (up to 20 characters)" 



                        << endl << "\t" << ": " ;



                fflush(stdin) ; 



                gets(studentscore) ;



                



                cout << "\n\t" << "3) Now, enter the enter the students score: " 



                        << endl << "\t" << ": " ;



                fflush(stdin) ;



                gets(score) ;







        // the info is then stored in the array 'Scores' 



                strcpy(The_Scores[num_students].student, score);  



                strcpy(The_Scores[num_students].studentscore, score);



                strcpy(The_Scores[num_students].student_name, student_name) ;



                The_Scores[num_students].studentscore = studentscore ;



                The_Scores[num_students].how_many = how_many; 



                num_students++;  // increment after adding another score



        }







  // if there is a match with a student's name already in inventory, user is notified



  //if sutdents name is there option to update score is given



        {



                cout << setw(59) << "The student's name is already in the list." << endl ;



                cout << setw(70) << "Do you want to update the his/her Score (Yes/No)? " ;



                cin >> choice ;



                cout << endl ;











        if (choice == 'Y' || choice == 'y')



                {



                        cout  << "Enter students new score: " ;



                        fflush(stdin) ;                



                        cin >> new_score ;



                        The_Scores[i].student_name, score = The_Scores[i].student_name, new_score  ; //not sure if its right



                }



        }



        cout << endl ;



}        //end of function

Thanks for the help!

studentname is a char, strcmp expects char*, so give it the address of student name.

Code:

while (strcmp(score, &(The_Scores[i].student_name) )!=0 && i <=num_students)

And unless all your students of single character names (you've said upto 20 ), this ain't going to work.

Thanks a million leonscape!!

One of these days I'll go from trying to learn C++ to kinda knowing C++

Thanks again!

My advice, would be not to use char*, but use the string class from the STL. This would cure most of your problems. you've included the header why not use it?

if ( score != The_Scores[i].student_name && i <=num_students )

Could you explain it a little more, I don't quite understand what you meen.

I'm still very new to programming, and trying to get an understanding of it all.

char is a single character, ( as in studentname ) char* is a pointer to a char. arrays of chars are used for strings. a char array without an index is also a char*.

string is a c++ class. Its very useful, as unlike a char array, its dynamically sized ( no need to worry so much about its length. ) and can beused with operators.

eg.

Code:

string str2;

str2 = "hello world.";

if ( str2 == "hello" )

        str2 += "Adding letters";

str2 = str2 + "adding letters";

No need for all the extra functions. They work as you would expect. I just think it would be easier for your code.

Ok I get it, thanks again leonscape!
