Extracting and storing data to ostream - c++

Question

Is it possible to store data to an ostream like this
void write(std::ostream& os){
int x,y = 0; bool b = true;
os<<x<<" "<<y<<" "<<b<<std::endl;
}
and then extract data from it like this
void read(std::istream& is){
unsigned int x,y,b;
is>>x>>y>>b; // I want to take x,y,b and make store them in a object but it is not important I want to know if I can extract information from istream like this and use x,y,b
}
I tried to make a simple program to just try that
#include <iostream>
#include <fstream>
#include <string>
int main(int argc, char const *argv[]) {
std::fstream file(argv[1]);
if (!file.is_open()){
std::cerr<<"erreur"<<std::endl;
return 1;
}
bool v = false;
size_t x = 1;
size_t y = 2;
for(size_t i=0;i<4;i++) {
file<<v<<" "<<x<<" "<<y<<std::endl;
}
for (size_t j = 0; j < 4; j++) {
bool b; size_t a; size_t c;
file>>b>>a>>c;
std::cout<<b<<a<<c<<std::endl;
}
return 0;
}
but my output is this:
026422044
026422044
026422044
026422044

Answer 1

After closing and reopening the file my problem fixed.
#include <iostream>
#include <fstream>
#include <string>
int main(int argc, char const *argv[]) {
std::ofstream file(argv[1]);
if (!file.is_open()){
std::cerr<<"erreur"<<std::endl;
return 1;
}
bool v = false;
size_t x = 1;
size_t y = 2;
for(size_t i=0;i<4;i++) {
file<<v<<" "<<x<<" "<<y<<std::endl;
}
file.close();
std::ifstream file1(argv[1]);
if (!file1.is_open()){
std::cerr<<"erreur"<<std::endl;
return 1;
}
for (size_t j = 0; j < 4; j++) {
size_t b; size_t a; size_t c;
file1>>b>>a>>c;
std::cout<<b<<a<<c<<std::endl;
}
return 0;
}
