Question

This is an external javascript file

// Problem 1:   Declare the variables num1, num2, ans1,
//               greet1, greet2. Then initialize them to
//               hold the values 1, 2, 0, "Hello", and
//               "World", respectively.
var num1 = 1;
var num2 = 2;
var ans1 = 0;
var greet1 = "Hello";
var greet2 = "World";

// Problem 1a:   Display the values stored in the previous
//               variables in the console
<script>
console.log(num1);
</script>

// Problem 2:   Preform the following arithmetic using
//               the variables declared previously. Display
//               the result in the document using the ids: in1
//               in2, out1, and p2_subTitle for input1, input2,
//               output1, and subtitle, respectively.
//               1) num1 + num2
//               2) num2 - ans1
//               3) num2 * 10
//               4) num1 / 2
//               5) 21 % 7

// Problem 3:   Explain using single or multi-line
//               comments what the following is doing.
//               Then display the results on the console.
//               (Be concise and detailed when explaining)
//               1) num1 + num2 + "3"
//               2) "3" + num1 + num2

// Problem 4:   Prompt the user twice as follows:
//               "Please enter the first value: "
//               "Please enter the second value: "
//               and store the values in num1 and num2,
//               respectively. Display them in console.

// Problem 5:   Create the following program:
//               AbsoluteValue Pseudo-code (T7A slide 12)
//               get number
//               if(number < 0) then
//                   set number to (number * -1)
//               endif
//               display number

// Problem 6:   Create the following program:
//               IsPositive Psuedo-code (T7A slide 13)
//               get number
//               if(number less then 0) then
//                   display "positive"
//               otherwise
//                   display "non-positive"
//               endif

// Problem 7:   Create the following program:
//               Convert Celsius to Fahrenheit Algorithm
//               Formula: F = (C * 9/5) + 32
//       1) Declare variable named celcius and
//           fehrenheit
//       2) Prompt user to enter degree in Celcius
//           and store in appropriate variable
//       3) Calculate the Fehrenheit using formula
//           above and store in appropriate variable
//       4) Display the result as follows:
//           celcius " Celcius degrees is " fehrenheit " Fehrenheit degrees."

// Problem 8:   Display the following messages based on the
//               temperature of fehrenheit.
//               90 and above: "It's too hot man!!"
//               between 89 and 75: "It's a nice day."
//               74 and below: "It's too cold!"

Answer 1

Solution (1) ?

<script>

console.log(num1);

console.log(num2);

console.log(ans1);

console.log(greet1);

console.log(greet2);

</script>

Solution (2) ?

console.log(“Addition: ”+(num1+num2));

console.log(“Subtraction: ”+(num1-ans1));

console.log(“Multiplication: “+(num2*10));

console.log(“Division: ”+(num1/2));

console.log(“Mod: “+ (21%7))

Solution (3) ?

Single line comments:-> Single line comment is used for make a line commented which is fit in one line only and We use the (//) to comment a line.

Such as :- Single Line Comment

Multiline Comment:--> Multiline comment is used when comment is not fits in one line. We use (/*) as start and (*/) as end for multiline comment..

Such as /*This is multiline comment*/

1. num1 + num2 + "3"

? Adding num1 and num2 and concatenating string “3” at the end of result

2. "3" + num1 + num2

? Concatenating “3” with result of (num1+num2)

Solution (4)?

num1 = prompt("Please enter the first value: ")

num2 = prompt("Please enter the second value: ")

console.log(num1)

console.log(num2)

Solution (5) ?

num1 = prompt(“Enter number: ”)

if(num1 <0)

num1 = num1*-1

console.log(num1)

Solution (6) ?

num1 = prompt(“Enter number: ”)

if(num1 <0)

console.log(“positive”)

else

console.log(“non – positive”)

Solution (7) ?

var celcius = 0;

var fehrenheit =0;

celcius = prompt("Enter degree in celcius: ");

fehrenheit = (celcius*(9/5))+32;

console.log(celcius+" Celcius degrees is "+fehrenheit+" Fehrenheit degrees" );

Solution (8) ?

var celcius = 0;

var fehrenheit =0;

celcius = prompt("Enter degree in celcius: ");

fehrenheit = (celcius*(9/5))+32;

document.write(celcius+" Celcius degrees is "+fehrenheit+" Fehrenheit degrees" );

if (fehrenheit>=90)

console.log("It's too hot man!!")

else if(fehrenheit >=89 && fehrenheit <=75 )

console.log ("It's a nice day.")

if(fehrenheit <= 74)

console.log ("It's too cold!")
