What is wrong with this piece of code?

It gives an empty output, instead of printing the contents of file stored as a.txt, what exactly is the problem with this?
It is working correctly for me. Are you sure youre textfile is in the right location? It should be in the same folder as your C++ project.
You should always check to see if the file you are trying to open exists or can be openend at all.
(see:
http://www.cplusplus.com/reference/fstream/ifstream/is_open/ for more detail)

string* readData(string array[])
{
ifstream read;
read.open("a.txt");
if(!read.is_open())
cout << "something went wrong!" << endl;
else
{
int i=0;
string a;
while(getline(read, a))
{
array[i]=a;
i++;
}
read.close();
}
return array;
}
