I've been at this for hours and I cant figure out why I can't convert the text in a txt file to a simple char array
Code:
// inFix to post fix converter
//Gary Chapman CMPS 401
//This does it correctly but, the User must type in the statement but they are given what to type.

#include<iostream>
#include<stdio.h>
#include<conio.h>
#include<vector>
#include<string>
#include <stdlib.h>
#include <stdio.h>
#include<stdlib.h>
#include<fstream>



const int size =50;
char postfix[size],stack[size];
int top=-1;

int precedence(char ch);   //  get the precedence of the operator
char pop();  // pop an element from the stack
char topelement();  // returns the top element of the stack
void push(char ch);  // pushes an element into the stack

using namespace std;

int main()
{
   
string getdata;
    int cont=0;
    fstream data;
    data.open("C:\\InFix.txt",ios::in);
 while(!data.eof()){
        data.getline(getdata,sizeof(data));
        cout<<getdata<<endl;
    }
    system("pause");


   ifstream inFile("C:\\InFix.txt");

   string word;

     cout << "Please type The following statement" ;
     cout << "\n" ;
     
       
              cout << "\n";
             cout << "THis will convert what is in InFix.txt to Post Fix";

     char ele,elem,st[2];
     int prep,pre,popped,j=0,chk=0;
     strcpy(postfix," ");
    char dirt[size] = "lol";
