Answer:
the mouse is an optical mouse
Explanation:
The user's mouse does not have a ball to be cleaned when it does not work right because he or she is using an optical mouse. This type of mouse does not use the old-ball-system, but rather uses a light source, which usually consist of a light detector and a light-emitting diode, and this set-up ensures that movement is detected relative to a surface and hence the cursor is moved too.
Answer: Stubs, data flow analysis, capture-replay tools and mock object are useful during the system testing.
Explanation:
Stubs hold the predefined data and used it to answer calls during testing. Stub act as an object and test scrub simulated the charactertics of software components.
Data flow analysis used in the programming of software components by using the control flow graph. It basically focused on the data variable and their definite values. It is used in the form of whitepox testing.
Capture replay tool is used as aggression development test and during testing it records all the events. By using playback it also compared the results in the testing.
Mock object are used to verified all the expected results and behavior during testing. Mock objects are mainly used in unit testing.

2. fstream //fstream is used for input and output for files
//just like iostream for input and output data
3. tellp(); //tellp returns the "put" or write position of the file.
4. ios::ate //ate meaning at the end, sets the file output at the file end
5. binary files //binary files only store 0s and 1s
6. seekg() //seekg is used to move write position of the file
7. put //this is used to "put" or set records or arrays to a single file
8. std::ws
, skips //the std::ws is used to discard leading whitespace from an //input stream
