country , countrylanguage and city are the table names.

country and countrylanguage are joined based ON country.Code = countrylanguage.CountryCode

What set of code correctly initializes all elements of the array ar to the value 0, given the declaration

Veronika [31]

Answer:

The correct answer is:

C. ndx = 0;

while (ndx < 3) {

ar[ndx] = 0;

ndx++;

}

Explanation:

The declaration given is:

int ar[3];

This means the array consists of three locations and is named as ar.

We know that the indexes are used to address the locations of an array and the index starts from 0 and goes upto to 1 less than the size of the array which means the indexes of array of 3 elements will start from 0 and end at 2.

Now in the given options we are using ndx variable to run the while loop.

So the code to assign zero to all elements of array will be

ndx = 0;

while(ndx<3)

{

ar[ndx] = 0;

ndx++;

}

Hence, the correct answer is:

C. ndx = 0;

while (ndx < 3) {

ar[ndx] = 0;

ndx++;

}

omeli [17]

Answer:

For 1), you should also add that methods in C++ are called member functions. Thus, the difference between functions and methods in this context is analogous to the difference between functions and member functions in C++. Furthermore, languages like Java only have methods. In this case, functions would be analogous to static methods and methods would have the same meaning. For 2), you should add that a method is able to operate on the private instance (member) data declared as part of the class. Any code can access public instance data. A function is a mathematical construct. I would say all methods are functions but not all functions are methods
