When a photographer adjusts the f-stop, what are they working to change?
O the size of a RAW file
O the length of a telephoto lens
o the measurement of lens aperture
O the time between shots

Cprogram to find //perimeter of rectangle printf(" \n perimeter of rectangle \n"); printf(""); printf("\n enter width and length of the rectangle : "); scanf("%f%f", & width,& length); perimeter = 2 * (width + length); printf("perimeter of rectangle is: %.3f", perimeter);
