Explanation
- Headers:
<iostream>: For input and output operations.<vector>: For using thestd::vectorcontainer.<iomanip>: For formatting (though not strictly necessary here).
- Function
displayARFeed:- Parameters:
const vector<vector<char>>& feed: The camera feed represented as a 2D grid of characters.const vector<pair<int, int>>& objects: A list of positions for virtual objects to overlay on the feed.
- Functionality:
- Creates a copy of the feed to modify (
display). - Places virtual objects on the copy using the ‘*’ character.
- Prints the modified feed with virtual objects overlaid.
- Creates a copy of the feed to modify (
- Parameters:
- Main Function:
- Initialization:
- Sets the dimensions for the camera feed.
- Initializes the feed with a grid of ‘.’ characters representing empty space.
- Defines a list of virtual objects with specific (x, y) coordinates.
- Display:
- Calls
displayARFeedto print the camera feed with the AR overlay.

Notes:
- Text-Based Simulation: This example uses text-based representation to simulate AR. In a real AR application, you would overlay virtual objects on a real camera feed using graphical libraries and real-time image processing.
- Virtual Objects: The virtual objects are marked with ‘*’ in the feed to simulate their presence in the AR environment.
- Simplification: This program provides a basic introduction to AR concepts. Actual AR involves complex interactions with real-world data and advanced graphics.
