write string to txt file and print it later

[ashton vern]

im quite new to c++ and this is my problem
im writing a program where user can input a string and two integers of their choice
the inputs will then write into a file

let's assume that text file, "example.txt" is already exist with the contents of

hello world		1		2
i like you		3		4
c++ programming 	9		8

after the user inputs, the user is able to search strings in the text file.
for example, if the user search "hello world", it will print:

hello world
1
2

my problem is that, i cant search strings with white spaces in my text file
this is my program code so far :

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


using namespace std;


struct example {

	string title;
	int x, y;

};

int main(){
	example test;
	test.title = "" ;
	test.x = 0;
	test.y = 0;

	bool found = false;

	fstream testing;

	string search;


	if (testing.fail()){

		cout << "example.txt file not found!" << endl;
		return -1; //abnormal termiation. if something fail	
	}
	
	testing.open("example.txt", ios::out | ios::app);
	cout << "please enter a string" << endl;
	testing << "\n";
	getline(cin, test.title);
	testing << test.title;

	cout << "please enter an integer" << endl;
	cin >> test.x;
	testing << "\t" << test.x;

	cout << "please enter another integer" << endl;
	cin >> test.y;
	testing << "\t" << test.y;
	testing.close();



	cout << "what do you like to search?" << endl;
	cin.ignore();
	getline(cin,search);
	

	testing.open("example.txt", ios::in);
	while (!testing.eof()){
		
		testing >> test.title;
		if (test.title == search){
			testing >> test.x >> test.y;
			cout << test.title << endl;
			cout << test.x << endl;
			cout << test.y << endl;
			found = true;
		}


	}
	testing.close();

	if (found != true){
		cout << "not found" << endl;
	}



	return 0;
}

std::getline has 3 arguments, stream, destination variable and separators. Newline is by default a separator for std::getline, space will be taken.

std::getline(file, line, '\n');
