//* Activity 1: Arithmetic Operations
//* **************************************************************

//* Task 1: Write a program to add two numbers and log the result to the console.
const firstNum = 10;
const secondNum = 20;
const result = firstNum + secondNum;
console.log(`Result is : ${result}`);               // Output -> Result is : 30


//* Task 2: Write a program to subtract two numbers and log the result to the console.
const operand1 = 50;
const operand2 = 30;
const difference = operand1 - operand2;
console.log(`Difference is : ${difference}`);       // Output -> Difference is : 20


//* Task 3: Write a program to multiply two numbers and log the result to the console.
const firstValue = 11;
const secondValue = 10;
const product = firstValue * secondValue;
console.log(`Product is : ${product}`);             // Output -> Product is : 110


//* Task 4: Write a program to divide two numbers and log the result to the console.
const divisor = 5;
const dividend = 40;
const quotient = dividend / divisor;
console.log(`Quotient is : ${quotient}`);           // Output -> Quotient is : 8


//* Task 5: Write a program to find the remainder when one number is divided by another and log the result to the console.
const divisor1 = 5;
const dividend1 = 43;
const remainder = dividend1 % divisor1;
console.log(`Remainder is : ${remainder}`);         // Output -> Remainder is : 3   


//* **************************************************************
//* Activity 2: Assignment Operators
//* **************************************************************

//* Task 6: Use the += operator to add a number to a variable and log the result to the console.
let num1 = 15;
num1 += 100;                                        // num = 15 + 100
console.log(`Result is : ${num1}`);                 // Output -> Result is : 115   


//* Task 7: Use the -= operator to subtract a number from a variable and log the result to the console.
let value = 50;
value -= 45;                                        // value = 50 - 45

//* **************************************************************
//* Activity 3: Comparison Operators

console.log(`Result is : ${price1 > price2}`);      // Output -> Result is : false
console.log(`Result is : ${price1 < price2}`);      // Output -> Result is : true


//* Task 9: Write a program to compare two numbers using >= and <= and log the result to the console.
const cost1 = 150;
const cost2 = 200;

console.log(`Result is : ${cost2 >= cost1}`);       // Output -> Result is : true
console.log(`Result is : ${cost2 <= cost1}`);       // Output -> Result is : false


//* Task 10: Write a program to compare two numbers using == and === and log the result to the console.

//* '==' : The == operator compares two values for equality after converting both values to a common type (type coercion).
//* '===' :  The === operator compares both value and type without performing any type conversion.

const number = 15;
const number1 = '15';
console.log(`Result is : ${number == number1}`);    // Output -> Result is : true
console.log(`Result is : ${number === number1}`);   // Output -> Result is : false

const value2 = 40;
console.log(`Result is : ${value1 == value2}`);     // Output -> Result is : false
console.log(`Result is : ${value1 === value2}`);    // Output -> Result is : false


//* **************************************************************
//* Activity 4: Logical Operators
//* **************************************************************

//* Task 11: Write a program that uses the && operator to combine two conditions and log the result to the console.
const condition1 = true;
const condition2 = false;
console.log(`Result is : ${condition1 && condition2}`);     // Output -> Result is : false


//* Task 12: Write a program that uses the || operator to combine two conditions and log the result to the console.

const flag2 = false;
console.log(`Result is : ${flag1 || flag2}`);               // Output -> Result is : true


//* Task 13: Write a program that uses the ! operator to negate a condition and log the result to the console.
