Search struct and return

[hutty]

Hi,

I am trying to search a struct after I have loaded data via text file. I looking to look up a player and return his/her average scoring. I copied an online search program and tried to mirror it somewhat, but getting the following error:

[Error] cannot convert 'main()::player' to 'std::string* {aka std::basic_string<char>*}' for argument '1' to 'int searchList(std::string*, int, std::string)'

Any ideas? thanks

  // This program demonstrates the searchList function,
 // which performs a linear search on an integer array.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <cstring>
using namespace std;

// Function prototype
int searchList(string [], int, string);

const int SIZE = 10;

int main()
 {
 int tests[SIZE] = {87, 75, 98, 100, 82}; //online example
 
 struct player
{
              char name[20];
                int game1;//mmddyyyy
                int game2;
                int game3;
                int game4;
                int game5;
                
}person;


int results; // Holds the search results
int num;
string scorer;
string srchPlayer;
float average=0;
ifstream infile;
    infile.open("stats.dat");
    while(infile>>person.name>>person.game1>>person.game2>>person.game3>>person.game4>>person.game5)
                 infile.close();


cout<<"enter player name: "<<endl;
//cin>>num;
cin>>scorer;
 // Search the array for the value 100
 //results = searchList(tests, SIZE, num);
results = searchList(person, SIZE, scorer);
 // If searchList returned -1, 100 was not found
 if (results == -1)
 //cout << "You did not earn 100 points on any test.\n"; //online example
    cout<<"Player doesn't exist";
 else
 { // Otherwise results contains the subscript of
 // the first 100 found in the array
 //cout << "You earned "<<num<<" points on test "; //online example
 cout << (results + 1) << ".\n";
 average = (person.game1+person.game2+person.game3+person.game4+person.game5)/num;
 cout<<"Player "<<results<<" is averaging "<<average<<" points per game";
 }
 return 0;
 }

searchList() expects an array of strings as the first argument. At line 46 you are passing person, which is a variable of type struct player.

Changing line 46 to results = searchList(person[i].name, SIZE, scorer); produced an error as well.

I pretty much took an online example and substituted. The only difference being an array versus struct.

A struct is not an array. They are two entirely different things. You can't do simple substitution without a LOT of code rewriting.

Okay...I think that's the answer I was looking for....Not that deep. I can continue using Excel VBA for what I am doing.

thanks
