Answer:

Variables are used to store values (name = "John") or expressions (sum = x + y).

Declare Variables in JavaScript

Before using a variable, you first need to declare it. You have to use the keyword var to declare a variable like this:

var name;

Assign a Value to the Variable

You can assign a value to the variable either while declaring the variable or after declaring the variable.

var name = "John";

var name;

name = "John";

7.8.1: Function pass by reference: Transforming coordinates. Define a function CoordTransform() that transforms the function's f

Lilit [14]

Answer:

Here is the CoordTransform() function:

void CoordTransform(int xVal, int yVal, int &xValNew, int &yValNew){

xValNew = (xVal + 1) * 2;

yValNew = (yVal + 1) * 2; }

The above method has four parameters xVal and yVal that are used as input parameters and xValNew yValNew as output parameters. This function returns void and transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew according to the formula: new = (old + 1) *

Here new variables are xValNew and yValNew and old is represented by xVal and yVal.

Here the variables xValNew and yValNew are passed by reference which means any change made to these variables will be reflected in main(). Whereas variables xVal and yVal are passed by value.

Explanation:

Here is the complete program:

#include <iostream>

using namespace std;

void CoordTransform(int xVal, int yVal, int &xValNew, int &yValNew){

xValNew = (xVal + 1) * 2;

yValNew = (yVal + 1) * 2;}

int main()

{ int xValNew;

int yValNew;

int xValUser;

int yValUser;

cin >> xValUser;

cin >> yValUser;

CoordTransform(xValUser, yValUser, xValNew, yValNew);

cout << "(" << xValUser << ", " << yValUser << ") becomes (" << xValNew << ", " << yValNew << ")" << endl;

return 0; }

The output is given in the attached screenshot

A python programmer is writing a function definition. What syntax should be used?

Kay [80]

Answer:

<u>Syntax of function in the Python Programming Language.</u>

def function_name():

'''body of the function or code'''

#calling of the function

function_name()

Note: In Python Programming Language, Indentation is sensitive if you not focus on the indentation then, you program occurs an indentation error.

Explanation:

In Python Programming language, we can use the "def" keyword to define a function then we write the name of the function and then use parentheses for the argument list. "#" is used for the single-line comment and " ''' ''' " is used for the multiple line comment.

A function is the part or module of the program which provides users the feature of reusability of that code anywhere only by calling them.
