CPP/IO/ReadingLines

Galik: Created page with '==ReadLines.cpp== <source lang="cpp"> #include <string> #include <fstream> #include <iostream> int main() { // Open file for input std::ifstream ifs("input.txt"); std::strin…'

==ReadLines.cpp==
<source lang="cpp">
#include <string>
#include <fstream>
#include <iostream>

int main()
{
// Open file for input
std::ifstream ifs("input.txt");

std::string line; // string to contain each line

// By placing the getline() function
// inside the while condition you
// guarantee that inside the loop
// the read was successful and that line is valid.
while(std::getline(ifs, line))
{
// deal with each line here...
std::cout << line << std::endl;
