For Loop to Read From File C++

while loop and read file program

i take to write a plan that 2. Apply file I/O to read the integers from the file. If the data file is saved in your project binder, only
the file name is needed when you lot declare an ifstream variable, otherwise, a path to the file is
required.
3. Suppose the ifstream variable is input, and so apply while(!input.eof()) for testing whether the cease
of file is reached.

This is all I accept so far... Delight help!

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
ifstream inFile;

inFile.open (" hw4dataf11.txt")

y=ten%2
if (y=0) = even;
if (y=one) = odd;
}

// reading a text file #include <iostream> #include <fstream> #include <string> using namespace std; int main () { cord line; ifstream myfile ("example.txt"); if (myfile.is_open()) { while ( myfile.skilful() ) { getline (myfile,line); cout << line << endl; } myfile.close(); } else cout << "Unable to open up file"; return 0; }

Woo my 100th post :D

In that location are so many things wrong nearly this information technology hurts a little.

@xander337 be squeamish, he is just starting :P

Here is a complete program that will take each line (if it is a number) and output "Odd" or "Even"

#include <iostream> #include <fstream> #include <string> #include <stdlib.h> #include <sstream> using namespace std; // Determines if the string is a number bool isNumeric(string pszInput); int main () { // Hold the line in the file string line; // Open the file ifstream myfile ("example.txt"); if (myfile.is_open()) { // While the file is good while (myfile.skillful() ) { // Get the current line in the file getline (myfile, line); // Verify that the line is an integer if (isNumeric(line)) { // Convert 'line' to an integer and summate if (atoi(line.c_str())%2 == 0) { cout << "Even\due north"; } else { cout << "Odd\n"; } } } myfile.close(); } else { cout << "Unable to open up file\n"; } // Exit return 0; } // Determines if the cord is a number bool isNumeric(string pszInput) { istringstream iss(pszInput); double dTestSink; iss >> dTestSink; // was any input successfully consumed/converted? if (!iss) { return false; } // was all the input successfully consumed/converted? return (iss.rdbuf()->in_avail() == 0); }

it might be a petty shotty.. whipped it upwardly in a couple minutes

No I mean. Well for ane he posted his thread in the wrong forum. He didn't and then much ask a question as plead for help, oh and he didn't even thinly vale the fact that this is a homework assignment that you just gave him a consummate answer to. Also no lawmaking tags (only that's nitpicking.)

I didn't hateful there was and then much wrong with his code, I meant there was then much wrong with this thread.

I didn't think of that... I learn c++ on my own so my first thoughts are that it is a personal projection... >_>
