Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

#include <fstream>
#include <iostream>
#include <cstring>

using namespace std;

void sort(string names[], int count);
int main()
{
   // Declaring variables
string* names = NULL;
  
int count = 0;
string name;
ifstream dataIn;
  
// open the input file
dataIn.open("strnames.txt");
/*
* checking whether the file name is valid or not
*/
if (dataIn.fail())
{
cout << "** File Not Found **";
return 1;
}
else
{
/*
* Reading the data from the file
*/
while (dataIn >> name)
{
count++;
}
/*
* closing the file
*/
dataIn.close();

// Creating array dynamically
names = new string[count];

dataIn.open("strnames.txt");
for (int i = 0; i < count; i++)
{
dataIn >> names[i];
}
dataIn.close();

cout << "Before Sorting :" << endl;
for (int i = 0; i < count; i++)
{
cout << names[i] << endl;
}
sort(names, count);
cout << "After Sorting :" << endl;

for (int i = 0; i < count; i++)
{
cout << names[i] << endl;
}
}

return 0;
}

// this function will sort the string in lexical order
void sort(string names[], int size_of_arr)
{
string temp;
for (int i = 0; i < size_of_arr - 1; i++)
{
for (int j = 0; j < size_of_arr - i - 1; j++)
{
if (names[j] > names[j + 1])
{
temp = names[j];
names[j] = names[j + 1];
names[j + 1] = temp;
}
}
}
}
