C++ program reports "Process terminated with status -1073741510" - c++

Question

I am doing a algorithm and data structure exercise in C++ which requires to read a ten-word txt file then display them in a reserved order by using a stack without STL, class or struct. All the code looks good but it display nothing when I actually run it.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int mindex = -1;
string word[10];
void push(string p);
void top();
void pop();
bool isEmpty();
int main()
{
string filename,eli;
cout << "Please input a file name" << endl;
cin>>filename;
ifstream inData;
inData>>eli;
inData.open(filename);
if (!inData)
{
cerr<< "Error opening : " << filename << endl;
return -1;
};
while (inData >> eli)
{
if(inData.fail()){
break; }
else push(eli);
}
while (!isEmpty()){
top();
pop();
}
inData.close();
return 0;
}
void push(string p){
index++;
word[mindex] = p;
}
void pop(){
mindex--;
}
void top(){
cout<<word[mindex]<<" ";
}
bool isEmpty(){
return (mindex<0);
}

There are several mistakes and assumptions here that could go wrong. I will only focus on the immediately obvisous.
#include <iostream>
#include <fstream>
#include <string>
using namespace std; // only for demos/slideware/toy projects.
int mindex = -1;
string word[10]; // we will only ever get 10 strings?
// 10 is a magic number use a const like const int maxWords = 10;
// using std::array will catch problems like this, std::vector can be used to dynamically resize the array.
void push(string p);
void top();
void pop();
bool isEmpty();
int main() {
string filename,eli;
cout << "Please input a file name" << endl;
cin>>filename;
ifstream inData;
inData>>eli; // reading from not open file!!!
inData.open(filename);
if (!inData) {
cerr<< "Error opening : " << filename << endl;
return -1;
};
while (inData >> eli) {
if(inData.fail()) {
break;
} else
push(eli);
}
while (!isEmpty()){
top();
pop();
}
inData.close();
return 0;
}
void push(string p){
index++; // did you mean mindex???
word[mindex] = p; // fatal error if mindex is not at least 0.
}
void pop(){
mindex--;
}
void top(){
cout<<word[mindex]<<" ";
}
bool isEmpty(){
return (mindex<0);
}
A check for mindex at/above 10 should be done somewhere unless you are absolutely sure there will never be more than 10 words.
