```Write a program which stores 2 coordinates of a 2-D plane with the pair data structure and calculate the distance between them. The first coordinate is point1( 3, 5 ) and the second coordinate is point2( 10, 6 ).

#include #include #include using namespace std; int main() { pair<int, int> point1; pair<int, int> point2; // Write your code here cout << "Distance = " << distance << endl;

return 0; } /* Sample Run: Distance = 7.07107 */```

What I have tried:

```#include <iostream>
#include <utility>
using namespace std;

int main(){
pair<int, int> (3,5);
pair<int, int> (10,6);

cout << "Distance = "<< distance << endl;
return 0;
}```

## Solution 1

In order to calculate the distance you need to apply Pythagorean theorem.

This is not a code on order service !

You are learning and homework is training, nobody can do it for you.
Do you think Usain Bolt asked someone to train for him when he was a beginner ?

You show no attempt to solve the problem yourself, you have no question, your main effort is pasting the requirement, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

## Solution 3

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]

## Solution 4

```#include <iostream>
#include <utility>
using namespace std;

int main(){
pair<int, int=""> (3,5);
pair<int, int=""> (10,6);

cout << "Distance = "<< distance << endl;
return 0;
}
this what i did and i don't know what to write after the two pairs</int,></int,></utility></iostream>```

You need to provide a variable name for each pair.
```pair<int, int> pointA(3, 5);
pair<int, int> pointB(10, 6);
```

You then need to use their values to calculate the distance via geometry. Draw the points on a piece of paper and think how you would calculate the distance between them.
