The program would not generate an error if the var_str list have up to 5 elements

<h3>How to determine the error?</h3>

The operation is given as:

Assign a value to that same index

This is represented as:

var_str[5] = "r"

The representations from the above code segment are

List = var_str
Index = 5
Value = "r"

When a value is assigned to an index, the value at the index is updated to the new value, provided that the index exists in the list.

This means that the program would not generate an error if the var_str list have up to 5 elements

The use of fewer syllables and shorter words is likely to make teens leave out important aspects of verbal communication and may lead to misinterpretation of messages.
3)Dialogue- Internet communication mostly takes place in the written form as opposed to the spoken form. Teens primarily communicate through textual posts,emails e.t.c all of which are in the written form.
Since written communication typically occurs in form of monologue, teens addicted to the internet may find it difficult to engage in dialogue a feature of verbal communication.For instance they may find it difficult to effectively use aspects of verbal communication such as tonal variation turn taking and speed.

Which of the following would be a valid method call for the following method? public static void showProduct (int num1, double n

Alenkinab [10]

Answer:

showProduct(int,double)

for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.

Explanation:

The code is

<em>public static void showProduct (int num1, double num2){</em>
<em> int product;</em>
<em> product = num1*(int)num2;</em>
<em> System.out.println("The product is "+product);</em>
<em> }</em>

showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.

If showProduct( 10,10.0) is called the output will be 'The product is 100'.

Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.

This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
