saving multiple struct based records generic question

[technologist]

ow do I make a struct of variables/values that can be saved in an array like fashion? Meaning I want to make 10 records of the struct below for example of 10 people's hair color, eye color and age. Do I make an array of struct objects?

struct foo
{
   int age;
   int eye_color;
   int hair_color;
};

int main()
{
Foo foo
//set a record
foo.age = 45;
foo.eye_color = hazel;
foo.hair_color = brown;
//make 10 new foo records...how to

}

Yes. That's exactly what you do.

Something like

foo myArray[20];

Hi,

Declare a std::vector<foo> MyFooData;

Then use MyFooData.push_back or emplace_back to put a foo into your vector.

push_back pushes an already created obj onto the vector, while emplace_back constructs a foo obj at the end of the vector. So this means foo needs to have a constructor.

foo.eye_color = hazel;
foo.hair_color = brown;

int is perhaps not a good type for these, did you mean std::string ?
