When I try to use Case 3 to update player record the program removes some of my players information instead of updating the selected players information..

Using Visual Studio for C++

Any Thoughts?

Here is the Code:

#include

#include

#include

using namespace std;

struct FootballPlayer

{

string name;

string position;

int touchdowns;

int catches;

int passingYards;

int receivingYards;

int runningYards;

};

void printData(struct FootballPlayer players[10], int size);

void writeDataToFile(struct FootballPlayer players[10], int size);

int searchNameStr(struct FootballPlayer players[10], int size, string searchName);

int main()

{

struct FootballPlayer players[10];

int i = 0;

ifstream infile;

//Reading data from file

infile.open("Ch9_Ex7data.txt");

while (!infile.eof())

{

infile >> players[i].name;

infile >> players[i].position;

infile >> players[i].touchdowns;

infile >> players[i].catches;

infile >> players[i].passingYards;

infile >> players[i].receivingYards;

infile >> players[i].runningYards;

}
