I made a program that ask for 20 names and grade.
Then the program automatically arrange it alphabetically.
Now I tried to output the result the a ".txt" file. But the .txt file didn't arrange the names in the notepad
I want to know what I did wrong and how can I fix my program to output the 20 results alphabetically

What I have tried:

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

int main()
{
 ofstream outputFile;
 outputFile.open("earlfoz.txt")
 string name[20];
 int grade[20];
 int index[20];
 int i, j;

 for(i=0;i<20;i++)
 {
  cout << "Please enter name: ";
  cin >> name[i];
  outputFile << name[i] << endl;
  cout << "Please enter grade: ";
  cin >> grade[i];
  outputFile << grade[i] << endl;
  
 }

 for(i=0;i<20;i++)
 {
  index[i]=i;
 }

 for(i=0;i<20;i++)
 {
  for(j=i+1;j<20;j++)
  {
   int temp;
   
   if(name[index[i]] > name[index[j]])
   {
    temp = index[i];
    index[i] = index[j];
    index[j] = temp;
   }
  }
 }
 cout << endl;

 for(i=0;i<20;i++)
 { 
  cout << name[index[i]] << "        "
   << grade[index[i]] << endl;
 }

 cin.ignore();
 cin.get();

 outputFile.close();
 cout << "Done!\n";
 
}

is there a reason you're using your own sort mechanism ? if so, I'd suggest stepping through your program with the debugger to make sure its doing what you want it to do - not what you 'think' the computer should be doing.

Else, there's always qsort https://www.tutorialspoint.com/c_standard_library/c_function_qsort.htm or http://www.anyexample.com/programming/c/qsort__sorting_array_of_strings__integers_and_structs.xml

First, add a semi-colon to this:

outputFile.open("earlfoz.txt");

Next, comment out the outputFile in

for(i=0;i<20;i++)
{
 cout << "Please enter name: ";
 cin >> name[i];
 //outputFile << name[i] << endl;
 cout << "Please enter grade: ";
 cin >> grade[i];
 //outputFile << grade[i] << endl;
}

then output the sorted result line by line to file

for(i=0;i<20;i++)
{
  outputFile << name[index[i]] << "        "
  << grade[index[i]] << endl;
}

Lets guess, you get the sorted list on screen but the file contain the list as it was input.
Reread your code and pay attention to what you do with outputFile, a bell should start to ring.

When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute, it is an incredible learning tool.

Debugger - Wikipedia, the free encyclopedia[^]
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]
Basic Debugging with Visual Studio 2010 - YouTube[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
