how to use getline to read a file in c++ code example

Example 1: c++ read file line by line

#include <iostream>
#include <ifstream>
#include <string>

using namespace std;

ifstream file("file.txt");
if (file.is_open())
{
	string line;
	while (getline(file, line))
    {
    	// note that the newline character is not included
        // in the getline() function
    	cout << line << endl;
    }
}

Example 2: getline of file C++

ifstream inFile;
string name;
int age;

inFile.open("file.txt");

getline(inFile, name); 
inFile >> age; 

cout << name << endl;
cout << age << endl;  

inFile.close();
