I beam jumps to location where the pointer is

When using programs like word or just typing (write now), the blinking beam jumps to the position where the pointer was. Sometimes it acts as I click on something when I didn't.

I don?t understand the use of pointers in C++


Pointers are variables which store memory address of other variables.
It is denoted by an astrix *
Pointers and normal variables must have same data types.
Need of Pointers:
As said pointers variables store memory addresses of other variables, this can be used when we want to perform some calculations on a variable, we pass the address of this variable to the function from using pointers, thus any changes made to the variable will directly affect the variable as it is pointed to the same memory location.
It can also be for pointing various memory locations e.g. video memory. In the days of Dos we could actually read and write directly on to the video memory using address 0xB8000000 hexa decimal address.
Declaring a pointer:
int a = 10;
int *p = &a;
Here are passing address of a to p. Make sure that the data types should be same.
When we use pointers as arrays, it is much faster then the usual array iterators.
int num[] = {43,52,54,53};
int i=0, *j;
j=&num[0];
while(i<=3) { cout<<"num ["<<i<<"] = "<<*j<<endl; j++; } // This peice of code is faster than following method
for (int i=0;i<=3;++) { cout<<"num ["<<i<<"] = "<<num[i]<<endl; }
As we are directly working on memory.
Pointers are most commonly used to allocate memory dynamically, using new operator.
int *p = new [10];
This code allocates for 10 integer type array dynamically.
Dont forget to release the reserved memory using new operator by delete operator.
delete []p; // Frees the reserved memory.
This is an overview of pointers, as it requires study and practice.
Please rate. Thanks :)

Pointer on laptop jumps to a different line while typing.


This may be caused by weak batteries, or interference by some nearby appliance (the worst case is another wireless mouse, of course: happened all the time in an office with six identical workstations, even to the two that were beyond a wall. But also wireless - not cellular - phones may interfere). Also the positions of receiver and mouse may play a part. Once sure the batteries work, try placing the receiver and mouse in different positions and see if it helps.
Otherwise, the receiver antenna could be defective.

Hello, this normally happens on laptops. I think that it is from the sensitivity of the touch pad. You would have to check the position of your hands when typing since when your finger happens to touch the pad unexpectedly, the cursor quickly jumps to where ever the mouse pointer is: As a result, whatever you type next will rather go there instead of your current position.
Hope that helps
Thanks
