Declaring a member as protected in the base class provides access to that member in the derived classes but not to anyone else.
Base class and derived classes are concepts of inheritance in the paradigm of Object Oriented Programming. Inheritance is the process in which a new class (called derived class) is created from an existing class (called base class).
When a drive class is created from the base class, it has access to some members of the base class. There are three types of access specifiers to declare members in the base class in order to provide their access in the derived classes.
The first is declaring a member as private. Private members of the base class cannot be accessed by anyone, even not by the derived classes. The second is declaring the base class members as public. Public members can be accessed by anybody including derived classes. The third type is declaring members as protected. Protected members of the base class have accessibility only in derived classes.
Thus, when a member is declared as protected in the base class, it gives access to that member in the derived classes but not to anyone else.

write a function fullwords(s) that returns a string no longer than 20 characters. if the string s is longer than 20 characters, just truncate at the space closest to the 20th position (so no word is truncated) and return it. if the string s is shorter 20 characters, just return it unchanged.
Assuming you mean a function that truncates a string to 20 characters:
function fullwords(s){
if (s.length > 20) {
//find the 20th character
var char20 = s.charAt(19);
//if it's a space, return the string up to that point
if (char20 == " ") {
return s.substring(0, 20);
}
//if it's not a space, find the closest space
else {
var spaceBefore = s.lastIndexOf(" ", 18);
return s.substring(0, spaceBefore);
}
}
//if the string is shorter than 20 characters, return it unchanged
else {
return s;
}
}
To use fullwords(), simply pass in a string as the only argument. The function will then return a string that is no longer than 20 characters. If the string you passed in was shorter than 20 characters, it will be returned unchanged.

breast cancer screening and health behaviors among african american and caribbean women in new york city.
A telephone-based survey regarding breast cancer screening (in terms of insurance status, marital status, and educational attainment) among 300 African American and Caribbean women in New York City aged 40 and over, it was found that they were no more likely to have had a mammogram than the foreign-born women.
Women with a provider referral were eight times more likely to have ever had a mammogram, after adjusting for insurance status and the source of care (AOR 8.01, 95%CI: 3.74-17.14). Compared to 77% of American-born women, just 52% of Caribbean women who were born abroad and have lived in the country for less than half their life had a provider ever recommend a mammogram.
The results support prior research on the significance of physician referral in increasing mammography screening among urban Black women, and they suggest that efforts to communicate breast cancer screening messages to Caribbean-born women should place a strong emphasis on the significance of providers.

Given a string variable s that has already been declared, write some code that repeatedly reads a value from console input into s until at last a y or y or n or n has been entered.
Answer:
s = "";
while (!(s=="Y" || s=="y" || s=="N" || s=="n"))
{
cin >> s;
}
The code for the String variable is described below.
To achieve the desired functionality of repeatedly reading values from console input into the variable s until either 'y' or 'n' has been entered, you can use a loop.
Here's an example of how you can implement this in Python:
s = ""
while s not in ('y', 'n'):
s = input("Enter a value (y/n): ")
# At this point, the user has entered 'y' or 'n'
print("You entered:", s)
In this code, the 'while' loop will continue executing as long as the value of s is not 'y' or 'n'.
The 'input()' function prompts the user to enter a value, and the input is stored in the variable s. The loop will keep repeating until the condition s not in ('y', 'n') is false.
Once the loop exits, it means the user has entered either 'y' or 'n', and you can proceed with further processing or printing the value if needed. In the example above, it simply prints the value of s using print().

Direct routing overcomes the efficiency of triangle routing, at the cost of complexity. uses a correspondent agent.
There are many different routing algorithms that can be used to route data packets across a network. One of the most commonly used algorithms is triangle routing, which is very efficient at routing data packets between three nodes. However, triangle routing can become very complex when there are more than three nodes in the network.
Direct routing uses a correspondent agent to route data packets between two nodes, without going through the intermediate node. This can make direct routing much more complex than triangle routing, but it also eliminates the need for the intermediate node to keep track of the data packets.
Direct routing is often used in networks where there are a large number of nodes, or where data packets need to be routed between nodes that are not all part of the same network. However, it is important to note that direct routing can also be used in smaller networks, where it can be more efficient than triangle routing.

should variables that contain numbers always be declared as integer or floating-point data types? why or why not? name potential examples.
No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.
It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.
Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.
Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.
In Python int, float, and complex are the data types used to declare number type variables.SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers. To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.JavaScript uses a single data type called 'number' to declare numbers.In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
