Using templates in classes

Question

I used a template within a c++ class. However, when I try to call a function using a template from another function in the class, I get an error. What should I fix?

void MyClass::Display()
{
    cout << "sum :   ";
    cout << setw(30) <<Add();
}
template <typename T>
T MyClass::Add()
{
    T sum=0;
    for (int i = 0; i < 15; i++)
    {
        sum += y[i];
    }
    return sum;
}

In this way, an error occurs in add() of the display part

Please provide a minimal reproducible example with the full error message — Alan Birtles

You want to use Add(). But you do not specify the template argument for Add() you want to use.
You can specify it by: Add<*type*>()
