Answer 1

You had a few issues, but I've corrected your code for you and it complies now.

1. When you copy/pasted the code into Code Playground, it replaced your whitespaces with periods, which was causing a problem with compiling the code.

2. You didn't have a main loop/function, so there was no entry point into your program.

3. At the top you were using your structs before you even created them, so I removed that from the top and placed it at the bottom inside of the main loop instead.

Posted a link to the code (if you need to copy/paste) and provided the code before for your viewing. Hope it helps! Good luck.

#include <iostream>

struct Size{
int width, height;

Size () {}
Size (int width, int height) {
this->width = width;
this->height = height;
}
};

struct Point {
int top, left;

Point () {}
Point (int top, int left) {
this->top = top;
this->left = left;
}
};

struct Rectangle {
Size size;
Point point;

Rectangle (Size size1, Point point) {
this->size = size1;
this->point = point;
}
};

int main() {
Size size(10, 10);
Point point(5, 5);
Rectangle rect(size, point);

std::cout << "Completed.";
return 0;
}
