Answer:
ls, cd, cat, nano, gedit
Explanation:
There are several commands that will help the sys admin navigate through files but the most common ones are ls and cd. The cd command is quite helpful especially if the sys admin wants to change the current working directory. The ls, however, is the go-to command when we want to navigate and list computer files and folders. Typing ls without invoking any arguments will list all the files in the current working directory. He can invoke extra arguments if he wants to like adding an -a and will list entries starting with . To open text files, the sys admin can use cat, nano, or gedit followed by the text file name to view contents in that file.
Answer:
for (int i = 0; i < 9; ++i)
{
int k = 0;
while (k < 20 && scotus[i][k] != '')
{
cout << scotus[i][k];
k++;
}
cout << "\n";
}
Explanation:
scotus here is a two dimensional array. It contains names of 9 justices. so the loop starts from 0 and ends when i points to the last name element in the array. Then a while loop is used to check that name is longer than twenty characters and will keep on printing each output on the separate line.
Another way to write this:
for (int i = 0; i < 9; i++){
cout << scotus[i] << "\n";
}
This loop will keep on executing and printing the names of the nine justices at every iteration until it reaches the end of the array (last element of the array scotus).
Answer:
The correct answer to the following question will be "Run-length encoding (RLE)".
Explanation:
RLE seems to be useful for replicated information, swapping it with a qualify as well as a copy of something like a repeat element.
- Optimized dictionary strategies construct a table of sequences, then substitute appearances of chords with simpler codes.
- This is a straightforward type of data compression, where data runs become stored as an individual data count as well as a value rather than as the initial run.
