Let’s say I have a list of points represented in cartesian coordinates (Ex. (x,y)). I’m trying to grab one of those points, and make it the origin of a polar plane, and get the polar coordinates of all of the other points.

Right now I have this:

**This is my point struct**

```
struct point
{
float x;
float y;
string type;
float toDegrees = (180/3.1416);
point(float x, float y)
{
this->x = x;
this->y = y;
}
void makePolar()
{
float oldX = this->x;
float oldY = this->y;
this->x = sqrt(pow(oldX, 2) + pow(oldY, 2));
this->y = atan(oldY/oldX) * toDegrees;
if (this->y < 0)
{
this->y = 360 + this->y;
}
}
};
```

**And here is where I’m trying to do what I just explained**

```
for (int i = 0; i < points.size(); i++)
{
for (int j = 0; j < points.size(); j++)
{
point temp = points[j];
if (points[i].x != points[j].x && points[i].y != points[j].y)
{
temp.x += points[i].x;
temp.y += points[i].y;
temp.makePolar();
}
}
}
```

In this snippet, "points" is a vector<point>.
