in c++ i have this lab to read from text file but i have errors in the header file and implementation file can you help me to fix it without change anything in the Lab2driver.cpp

Lab2driver.cpp

#include

#include

using namespace std;

#include "studentType.h"

//function prototype

void sort(studentType[], int);

const int SIZE = 5;

int main()

{

// creating an array of studentType's

studentType students[5];

//defining and opening the input file

ifstream data("lab2Data.txt");

// Read the data from the file

for (int pos = 0; pos < SIZE; pos++)

data >> students[pos];

// sort the array by LAST name (using the given sort function)

sort(students, SIZE);

// printing the array

for (int pos = 0; pos < SIZE; pos++)

{

students[pos].print(cout);

cout << endl;

}

return 0;

}

//function definition

void sort(studentType arr[], int s)

{

int index;

int smallestIndex;

int location;

studentType temp;

for (index = 0; index < s - 1; index++)

{

//Step a

smallestIndex = index;

for (location = index + 1; location < s; location++)

if (arr[location] < arr[smallestIndex])

smallestIndex = location;

//Step b

temp = arr[smallestIndex];

arr[smallestIndex] = arr[index];

arr[index] = temp;

}

}

studentType.h

#ifndef STUDENTTYPE_H #define STUDENTTYPE_H

#include #include class studentType

{ private: string firstName; string lastName; int credits; double gpa;

public: void getInfo(ifstream& in, studentType& s) {

getfName = firstName; getlName = lastName; getCridet = credits; getGpa = gpa; }

void print(ostream& out);

bool operator <(const studentType& s);

};

#endif

studentType.cpp (implementation file)

#include using namespace std; #include "studentType.h"

void studentType:: getInfo(ifstream& in, studentType& s) { in >> s.firstName; in >> s.lastName; in >> s.credits; in >> s.gpa; }

void studentType::print(ostream& out) { out << endl << "First Name : " << studentType::firstName << endl; out << "Last Name : " << studentType::lastName << endl; out << "Credits : " << studentType::credits << endl; out << "GPA : " << studentType::gpa << endl; }

bool studentType::operator <(const studentType& s) { if (lastName < s.lastName) return true;

else return false; }
