What are pointer to pointer?
A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
What is a USB laser pointer?
a USB laser pointer is simply a laser pointer powered by the USB socket.
Difference between void pointer and null pointer?
A Null pointer has the value 0. void pointer is a generic pointer introduced by ANSI. Before ANSI, char pointers are used as generic pointer. Generic pointer can hold the address of any data type. Pointers point to a memory address, and data can be stored at that address.
What is the small picture or icon on the screen whose position is controlled by the mouse?
The pointer.
What is the use of void pointer?
Void Pointer is a General purpose pointer ,that does not have any data type associated with it and can store address of any type of variable. Declaration: void * pointer_name;
Instrument used to measure the thickness of hair?
Micrometer caliper
What is the advantage of using a light beam as a pointer to measure all small deflections?
Using a light beam as a pointer allows for precise and accurate measurements of small deflections due to its ability to detect even slight changes in position. It eliminates parallax errors common in traditional pointer methods, ensuring more reliable results. Additionally, light beams do not exert any force on the object being measured, making them ideal for delicate or sensitive materials.
Can you measure the sugar content of a liquid with a laser pointer?
No, a laser pointer cannot measure the sugar content of a liquid. To measure sugar content, you would need a specialized device like a refractometer or a hydrometer. These tools work by measuring the refractive index or density of the liquid, which correlates with its sugar content.
What moves the mouse pointer?
In a ball mouse, the ball, which is moved by contact on a surface, has three directional roll sensors which transfer electrical signals to the computer which then moves the mouse pointer on the screen. In laser and optical mice, the roll sensors are replaced by lasers or infrared sensors, which detect which direction the mouse is moving. This is sent to the computer which moves the mouse pointer. Laser and optical mice are more accurate than ball mice, but don't work on reflective or transparen surfaces such as foil or glass, which is not a problem for ball mice.
In order to measure an air pressure change the set pointer is placed the?
The set pointer is placed to measure the reference pressure before the air pressure change occurs. This allows the gauge to accurately detect any pressure deviations relative to the initial reading.
Is there anything to do so my optical mouse doesn't move the pointer while it's about 5mm above my black mousepad?
Found a solution by downloading software for my mouse and calibrating the sensor
What is used to turn the pointer of a galvanometer?
A small current passes through the coil that actuates the pointer. When you select different ranges on the instrument you are in fact selecting different resistors so that the sensitivity of the pointer is changed.
Difference between pointer to constant and constant pointer?
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
What is triple pointer?
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
What are pointer to pointer?
A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
Are there sensors which can measure the strength of the grip?
Yes, many. force sensors, suitably arranged would do, so would pressure sensors. The simplest would be a spring with a pointer to measure displacement.
What is pointer of pointer?
pointer is the variable that holds the address of another variable
