Reading a file line by line using ifstream in C++
Hello, colleagues! I'm new to C++ and encountered a problem when reading a text file. I need to read the file line by line and process each line. I'm using ifstream, but something is going wrong.
Here's my code:
```cpp
#include
#include
#include
int main() {
std::ifstream file("data.txt");
std::string line;
while (!file.eof()) {
file >> line;
std::cout << line << std::endl;
}
file.close();
return 0;
}
```
The problem is that when I run the program, it only outputs the first word from each line, not the entire line. For example, if the file contains "Hello world", only "Hello" is output. I've read that I need to use getline, but I don't understand how to do it correctly. I've also heard that
