Create a C++ function that opens a stream of a connected USB camera
system
ek C ++ fnction banaaen jo connected USB camera kii ek stream kholta he
user
bilkul!yahan code he jo ek connected USB camera ke saath ek stream kii gai windo banaata he:

#include <opencv2/opencv.hpp>

shunya opencamerastream ()
{
    // difolt camera kholen
    CV :: VideoCapture Camera (0);
    
    if (!
        std :: cerr << "camera kholane main vifal" << std :: endl;
        waapas karnaa;
    }
    
    jabaki (sach) {
        // camere se ek frem padhein
        CV :: MAT frem;
        camera >> frem;
        
        // jaanchen ki kya frem khaali he
        if (frame.empty ())
