If someone wants to use a wireless keyboard and mouse with a laptop computer, below are the steps.
First check if there’s a USB receiver attached to the mouse or keyboard. If there is, see below steps.
1. Connect the USB receiver of both mouse and keyboard into the USB port of your laptop computer. Some USB dongle would ask you to install or add it your device, just click OK and then add.
2. Make sure that the batteries on your wireless keyboard and mouse are working. And also check if the keyboard and mouse are turned on or have power.
3. Check if there’s a “connected” indication for both wireless mouse and keyboard on your laptop. You can now use your wireless mouse and keyboard on your laptop.
If there’s no USB receiver, and you’re using a bluetooth wireless mouse and keyboard, below are some steps to follow.
1. Turn on bluetooth connection on your laptop.
2. Make sure that batteries are working and turn on both wireless mouse and keyboard.
3. On your laptop, find your wireless mouse and keyboard under bluetooth option and connect the devices. You can now use your wireless bluetooth mouse and keyboard for laptop.
Answer:
The correct answer to this question is: "this program give an error".
int i = 7; //declare a variable(i) and assign value.
while (i>=2) //use loop and check condition.i greater then equal to 2.
{
System.out.print (i +""); //print value of i.
if ((i%3) == 0) //hold remainder
{
i +2; //error.
}
else
{
i/=2; //hold Quotient
}
}
Explanation:
In the above program, there is an error in the if block because it is not the correct way to declare. To use the variable from the correct output we use a variable like this.
Example
int i = 7;
//declare a variable(i) and assign value.
while (i>=2)
//use loop and check condition.i greater then equal to 2.
{
System.out.print (i +""); //print value of i.
if ((i%3) == 0) //hold remainder
{
i =i+2;
}
else
{
i/=2; //hold Quotient
}
}
Output: 732
I can solve it with Java. Here it is:
areaOfSquare = stdin.nextDouble();
double sqrt = Math.sqrt(areaOfSquare);
if(Double.isNaN(sqrt)){
System.out.print("INVALID");
} else {
System.out.print(sqrt);
}
