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
C program pointers to pointers examples?
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;
What is generic pointer in C?
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
What does pointer to pointer finger mean?
yea that's why its called the point FINGER
Which two pointer does not increment or decrement in arithmetic array?
constant pointer and character pointer
What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
Which way does a compass needle usually point?
The needle, or "pointer", of a compass will always point North. See: http://en.wikipedia.org/wiki/Compass
Why does compass needle get deflected when brought near a bar magnet?
The compass needle gets deflected when brought near a bar magnet because the magnet induces a magnetic field around it. This field interacts with the Earth's magnetic field, causing the needle to align itself with the magnetic field lines. This alignment results in the needle pointing towards the North and South poles of the bar magnet.
What are the 2 different types of torque wrenches?
There are more than 2 types, but the most common 2 have a long pointer needle or a snap ratchet.
What part of an analog scale gives the most accurate reading?
The part of an analog scale that gives the most accurate reading is typically the pointer or needle. This is because the pointer directly indicates the measurement on the scale, making it easier to read the value precisely.
Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
What is a magnetic needle?
A magnetic needle is a small magnetized object, often shaped like a pointer, that aligns itself with Earth's magnetic field when freely suspended. It is commonly used in compasses to indicate geographic directions, with one end pointing towards the magnetic north. The needle's orientation helps navigators determine their heading relative to the Earth's magnetic poles.
Shifter engages only when arrow is in between letters no noise runs perfect just looks odd and just happened today?
Generally the pointer ["arrow"] is not directly connected to the transmission, and is loosely connected to the shift lever, or its linkage to the transmission, by a very flimsy cable or rod and connectors. The pointer is only a position indicator for the lever. If the transmission is operating properly as you describe, I suspect that the the only problem is that the linkage TO THE POINTER has been damaged or dislocated. Sometimes, if the needle linkage is a small cable, it is routed over a pivot or small pulley. If the cable has been dislocated, it will cause the needle to be dislocated also. j3h.
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.
A compass has a small balanced pointer that always points north-south this is because?
the compass needle is magnetized and aligns itself with Earth's magnetic field, which causes it to point north-south. This allows travelers to determine their direction accurately by observing the alignment of the compass needle with the Earth's magnetic field.
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
Why does a compass have lightweight magnet and frictionless bearing?
The pointer/magnet provides the opposite attractive force to align itself along the earth's magnetic field. The pointer/magnet must be lightweight so that it responds rapidly to turning, and so that it reduces friction from its weight as it rests on the supporting pin. The so-called "frictionless" bearing (the supporting pin) allows the compass pointer to spin freely in order to achieve said alignment with the earth's magnetic field. Low friction is necessary to allow the weak magnetic force on the pointer to overcome the friction between the pointer/magnet and the supporting pin.
