In C++, a struct (short for "structure") is a user-defined data type that groups related variables under one name. It’s similar to a class, but by default, its members are public rather than private.

In C++, double is a primitive data type used to store floating-point numbers with double precision. That means it can represent decimal numbers with more digits and greater range than a float.

The line for (Resource& r : resources) is a range-based for loop in C++, and it means:

“For each Resource object r in the container resources, do something.”

The switch statement in C++ is a control structure used to execute different blocks of code based on the value of a variable—typically an int, char, or enum. It’s a cleaner alternative to multiple if-else statements when you're checking the same variable against many values.

for (declaration : container) {

    // loop body

}
