streaming into string and char

[masterinex]

i have a text file called numbers.txt with the following content:

4 a astring

i want to stream into the char ch the letter 'a'
and stream into string s 'astring'

and display the output , but it is not working.

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

using namespace std;

int main()
{

	ifstream inFile;

	inFile.open("numbers.txt");

	if (inFile.fail())
	{
		cerr << "error opeining file" << endl;
		exit(1); 

	}

	int x, y;

	string s; 

	char ch[1]; 

	inFile >> x >> y;

	cout << "num 1 " << x << endl;

	cout << "num 2 " << ch << endl;

	cout << "num 3 " << s << endl;


	system("pause");

	return 0; 


}

Hello masterinex,

Try this:

        int x;

	string s; 

	char ch[1]; 

	inFile >> x >> ch;

        std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');   // <--- Needs the "limits" header file. To clear the \n from the input buffer after a cin >>.

        std::getline(infile, s);

and see what happens.

Hope that helps,

Andy

You are simply not reading the char.

If the file is number character string you need to read
inFile >> x >> ch >> s;

For example:

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

void waitForEnter();

int main()
{

    std::ifstream infile("numbers.txt");
    if (!infile)
    {
        std::cerr << "\nError opening file\n";
        exit(1); 
    }

    int x;
    char ch; 
    std::string s; 

    // File format is:
    // 4 a string
    // i.e. integer char string
    // So I need to stream all the three components:
    infile >> x >> ch >> s;

    std::cout << "number read: " << x << '\n';
    std::cout << "character read: " << ch << '\n';
    std::cout << "string read: " << s << '\n';

    waitForEnter();
    return 0;
}

void waitForEnter()
{
    std::cout << "\nPress ENTER to continue...\n";
    std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
}

Writing only

it is not working

, without adding the wrong output or the errors, is not of much help.
