Question

Give a C++ definition of a struct called pair that consists of two members. The first is an integer called first, and the second is a double called second. When you answer the questions, please provide the justification/process/mathematical process why and how you came up with your own answers.

Answer 1

In C++, a struct is a user-defined data type that can hold different types of data. A struct called pair with two members, an integer called first and a double called second, can be defined using the given code.

Step-by-step explanation:

In C++, a struct is a user-defined data type that can hold different types of data. To define a struct called pair with two members, we can use the following code:

struct pair {
int first;
double second;
};

This struct consists of an integer member called first and a double member called second. The integer member first can store whole numbers, while the double member second can store decimal numbers.
