To indicate something visible in the microscope, like say a part of that paramecium your teacher tells you to locate, or as a point of reference, if your subject is moving, or even as a means to make an estimated measurement of something, although a micrometer is better in this case.
A pointer to a function is the memory address that stores the address of a function, while the pointer itself is a function pointer.A pointer to a function might be defined as "int (*pf)(int, int);", while to actually point to the function, you would use a function pointer, such as "pf = &func;".
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
float *(*funptr)(int *); float *fun (int *); funptr= fun;
// declare a function int* function(int, int); or int* (function)(int, int); // declare a pointer to a function int* (*pointer_to_function)(int, int);

The ocular is the upper lens and objective is the lower lens
The function of the ocular (eyepiece) is to magnify the image produced by the objective lens in a microscope or telescope, allowing the user to see the image more clearly. It typically provides a fixed magnification power for the device.
Eyepiece Lens or Ocular Lens is the lens on top. This is use to see the things or objects to observe or to study.
The ocular lens magnify the image 10x.
The main magnifying parts of a microscope are the objective lens and the ocular lens. The objective lens magnifies the specimen being viewed, while the ocular lens further magnifies the image produced by the objective lens. Together, they help to achieve high magnification for detailed observation of microscopic structures.
The eyepiece, or ocular, is the lens at the top of a microscope that you look through. Its function is to magnify the image of the specimen that is produced by the objective lens, allowing you to see the details of the specimen more clearly.
The ocular lens used for nearsightedness is known as a diverging lens. It is also known as a concave lens.
Another name is eyepiece or eyepiece lens.
An ocular lens is the top part of a microscope it is the eyepiece that you look through. The ocular lens is there it magnify whatever if being viewed. It can be different strengths base on the size power of the lens.
ocular lens
The upper lens is called the ocular lens or the eyepiece.
The ocular lens is located at the eyepiece of a microscope and is used to magnify the image produced by the objective lens. The objective lens is located close to the specimen being observed and is responsible for gathering light and forming the initial image.
