Discard Single character in the array

[amayakichi]

Hello! I have a task to prompt user to enter file path, read it into array up to 1024 and discard single characters. I now that it is somehow connected to the ASCII and while i can think of how to discard symbols what to do with single letters?

Thank you!

#include <iostream>
#include <string>
#include <fstream>
#include<iomanip>
using namespace std;

void readTxt(string[]);


const int SIZE = 1024;

int main()
{
	string txtArr[SIZE];

	readTxt(txtArr);



	getchar();
	system("pause");
	return 0;
}

void readTxt(string txtArr[])
{
	string fileName;
	ifstream inFile;
	
	cout << "Enter Full File Path : "; //Will that work for location also?
	getline(cin, fileName);

	inFile.open(fileName.c_str());

	while (inFile.fail()) //Check for mistakes in opening file
	{
		cout << "Error! Please enter the file name: ";
		cin >> fileName;
		inFile.clear();
		inFile.open(fileName.c_str());
	}

	
	if (inFile)	//If the file opened successfully, process it
	{
		int count = 1;
		while (count < SIZE && inFile >> txtArr[count])
			
//I would enter for loop here to discard single characters
                count++;
	}

	inFile.close();
}
