Answer:
The answer is below
Explanation:
There are cases where the use of a NULL value would be appropriate in a computer programming situation. These cases can be summarily described below:
The first case is in a situation where the value of the attribute of a certain element is known to exist, but the value can not be found
The second case is in a situation where the value of the attribute of a certain element is not known whether it exists or not.

Answer:
Functions of an operating system. An operating system provides three essential capabilities: It offers a UI through a CLI or GUI; it launches and manages the application execution; and it identifies and exposes system hardware resources to those applications -- typically, through a standardized API.
Explanation:
operator
b.
mathematical expression
c.
variable
d.
Boolean expression
Answer:
Boolean expression
Explanation:
The operator '&&' is called AND operator. it provide the output base on the Boolean value on each side of AND operator.
it has four possible values:
First Boolean is TRUE and Boolean is TRUE, then result will be TRUE.
First Boolean is TRUE and Boolean is FALSE, then result will be FALSE.
First Boolean is FALSE and Boolean is TRUE, then result will be FALSE.
First Boolean is FALSE and Boolean is FALSE, then result will be FALSE.
Therefore, the correct option is Boolean expression.

Hint: Use two vectors, one for the strings, another for the frequencies.
Your program must define and use the following function: int GetFrequencyOfWord(vector wordsList, string currWord)
Answer:
/ declare the necessary header files.
#include <iostream>
#include <string>
#include <vector>
using namespace std;
// declare the main function.
int main()
{
// declare a vector.
vector<string> words;
vector<int> counts;
// declare variables.
int size;
string str;
cin >> size;
// start the for loop.
for(int i = 0; i < size; ++i)
{
// input string.
cin >> str;
words.push_back(str);
}
// start the for loop.
for(int i = 0; i < size; ++i)
{
int count = 0;
// start the for loop.
for(int j = 0; j < words.size(); ++j)
{
// check the condition.
if(words[j] == words[i])
{
count++;
}
}
counts.push_back(count);
}
// start the for loop.
for(int i = 0; i < size; ++i)
{
// display result on console.
cout << words[i] << "\t" << counts[i] << endl;
}
return 0;
}
