C++ Function Coding

Question

I just started learning functions. I'm trying to write this code with using a function to have a user input the names. I can't figure out what the argument should be. I thought I could put in getName(i.name) passing an array into it, but I'm doing it wrong. What should the correct parameter be?

void getName(Horse &);  //function prototype
struct Horse
{
    string name;
}
array<Horse, horseCount> Horses;
for (Horse &i : Horses)
{
    getName(i.name);
}
void getName(Horse &Nag)
{
    cout << "Enter a horse's name: ";
    getline(cin, Nag.name);
}

Answer 1

The correct parameter would be an object of type Horse. You can change your code to this. The below code seems to be just a snippet, I'm assuming it's part of a function body that you've defined.

i.name in this case is of type std::string, but your prototype of getName takes a Horse object, not a string.

for (Horse &i : Horses)
{
    getName(i);
}

void getName(Horse &Nag)
{
    cout << "Enter a horse's name: ";
    getline(cin, Nag.name);
}

Answer 2

You are passing a std::string to getName() when it actually expects Horse&.

You must call it as getname(i) to actually pass the Horse object.
