How to iterate through a list of objects in C++

You're close.

std::list<Student>::iterator it;
for (it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

Note that you can define it inside the for loop:

for (std::list<Student>::iterator it = data.begin(); it != data.end(); ++it){
    std::cout << it->name;
}

And if you are using C++11 then you can use a range-based for loop instead:

for (auto const& i : data) {
    std::cout << i.name;
}

Here auto automatically deduces the correct type. You could have written Student const& i instead.

It is also worth to mention, that if you DO NOT intent to modify the values of the list, it is possible (and better) to use the const_iterator, as follows:

for (std::list<Student>::const_iterator it = data.begin(); it != data.end(); ++it){
    // do whatever you wish but don't modify the list elements
    std::cout << it->name;
}

Since C++ 11, you could do the following:

for(const auto& student : data)
{
  std::cout << student.name << std::endl;
}

-> it works like pointer u don't have to use *

for( list<student>::iterator iter= data.begin(); iter != data.end(); iter++ )
cout<<iter->name; //'iter' not 'it'
