For a class Foo, one difference between a variable declared Foo * and a variable declared Foo & is that only the variable declared Foo & can potentially have the value NULL.
Select one:
a. FALSE
b. TRUE
Answer:
False.
Explanation:
When we declare a variable as reference type we have to initialize that variable otherwise the compiler will give error that the reference variable is not initialized.You also cannot initialize the variable Foo& with NULL value because it is a reference variable and we have to initialize it.
On the other there is no need to initialize the variable Foo * since it is a pointer it can also store NULL value.
So the answer is only Foo* can store NULL value not Foo &.
Which of the following statements about a stack is correct?

Then write a statement to output the month, a dash, and the year. End with newline. The program will be tested with inputs 1 2000, and then with inputs 5 1950. Ex: If the input is 1 2000, the output is: 1-2000 Note: The input values come from user input, so be sure to use cin statements, as in cin >> birthMonth, to get those input values (and don't assign values directly as in birthMonth
Answer:
// here is code in c++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main() {
// variables to read birth month and year
int birthMonth,birthYear;
cout<<"Enter the birth month:";
// read the birth month
cin>>birthMonth;
cout<<"Enter the birth Year:";
// read the birth year
cin>>birthYear;
// print the output
cout<<birthMonth<<"-"<<birthYear<<endl;
return 0;
}
Explanation:
Declare two variables "birthMonth" and "birthYear". Read the value of birthMonth and birthYear from user. Then print the birth month and birth year and a dash(-) in between them.
Output:
Enter the birth month:1
Enter the birth Year:2000
1-2000
Enter the birth month:5
Enter the birth Year:1950
5-1950
The program is an illustration of a sequential program, and it does not require loops, iterations or conditions.
The programming statements in C++, where comments are used to explain each line is as follows:
//This gets input for birthMonth
cin>>birthMonth;
//This gets input for birthYear
cin>>birthYear;
// This prints the month, a dash, and the year

The World Wide Web (not the Internet) went live in this decade:
Select one:
a. 1960s
b. 1970s
c. 1980s
d. 1990s
Answer:
d. 1990s
Explanation:
The World Wide Web is a kind of friendly information system that uses hypertext, and since its creation has made Internet available for most people.
The Internet already existed quite before the World Wide Web: the first computer network was ARPANET (created in 1969), a project of the Advanced Research Projects Agency of the United States Department of Defense.
Further developments in computers' protocols (ways in which computers communicate with each other) resulted in a network of networks, or the Internet, in 1983.
Although the World Wide Web was a proposal first published on March 12, 1989, by Tim Berners-Lee of the European Nuclear Research Center (CERN) --this is why it is considered that the World Wide Web was created in 1989-- the idea came into life at the end of the year 1990, for the following reasons:
After that proposal of 1989, Berners-Lee wrote another on May 1990, and in September 1990 he received support to develop those ideas.Some of the essential technologies needed to create the World Wide Web were already available by October 1990, that is, the HTTP (Hypertext Transfer Protocol), the HTML (Hypertext Markup Language) and the URI (Universal Resource Identifier), all considered been developed by Berners-Lee.On November 12, 1990, with the Belgian engineer Robert Cailliau, who was working in similar ideas, wrote a more formal proposal of such a system to share information across the CERN where they mentioned: "build a Hypertext project called WorldWideWeb" [Wikipedia, 2019].Well, by the end of December 1990, in a NeXT computer, and after the creation of the first web server and the first web page browser, the first web site, running at CERN, appeared on December 20, 1990.
This idea was rapidly adopted outside the CERN in 1991 and, by the end of the 1990s, more than 130 million people could access the Internet using the World Wide Web technology.
In conclusion, the World Wide Web went live in the decade of 1990s: was a project, a proposal by the end of 1989 and started to work as a fast-adopted technology at the beginning, and throughout, the 1990s.

Answer:
Following are the program in c++
if(score>= 90)
// check if score 90 or higher
{
comments = "Excellent"; // initialize comments to excellent
}
else if(score<90 && score >= 80)
// check if when score is between 80 and 89
{
comments = "Good"; //initialize comments to good
}
else
//when score is less than 80.
{
comments = "Try Harder"; //initialize comments to try harder
}
Explanation:
Following are the program in c++ language
#include<iostream> // header file
using namespace std; // namespace
int main() // main function
{
string comments; // variable
int score; // variable declaration
cout<<" enter score ";
cin>>score;
if(score>= 90)
{
comments = "Excellent"; // initialize comments to execellent
}
else if(score<90 && score >= 80)
{
comments = "Good"; //initialize comments to good
}
else
{
comments = "Try Harder"; //initialize comments to try harder
}
cout<<comments;
return(0);
}
Output:
enter score
