Answer:
True.
Explanation:
It is true that some applications work on some devices but not on others. This is so because it depends on the operating system of each device, that is, if the device has an operating system compatible with the application in question, said application will work, but if, on the contrary, the operating system is not compatible, the application will not be useful in this.
Answer:
B. 1 6 3
Explanation:
Given function definition for calc:
void calc (int a, int& b)
{
int c;
c = a + 2;
a = a * 3;
b = c + a;
}
Function invocation:
x = 1;
y = 2;
z = 3;
calc(x, y);
cout << x << " " << y << " " << z << endl;
- Since x is passed by value, its value remains 1.
- y is passed by reference to the function calc(x,y);
Tracing the function execution:
c=3
a=3
b=c+a = 6;
But b actually corresponds to y. So y=6 after function call.
- Since z is not involved in function call, its value remain 3.
So output: 1 6 3
The answer to this is Optical mouse.
The reason the answer is optical mouse is because the optical mouse is a computer mouse which uses a light source, typically a light-emitting diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.
Hope this helped :)
have a great day
