Questions Overview 📚

1️⃣ Check for a 3-Digit Number

Check if a given number is a three-digit number.
Code Snippet:

function Question1() {
    let num = 333;
    if (num >= 100 && num <= 999) console.log(num, "is a 3 Digit Number");
}

2️⃣ Profit or Loss Calculator 💹

Calculate profit, loss, and their respective percentages for given cost price (CP) and selling price (SP).
Code Snippet:

function Question2() {
    let cp = 100, sp = 150;
    if (sp > cp) {
        const profit = sp - cp;
        const profitPercentage = (profit / cp) * 100;
        console.log(`Profit of ${profit}`);
        console.log(`Profit Percentage of ${profitPercentage.toFixed(2)}%`);
    } else if (sp < cp) {
        const loss = cp - sp;
        const lossPercentage = (loss / cp) * 100;
        console.log(`Loss of ${loss}`);
        console.log(`Loss Percentage of ${lossPercentage.toFixed(2)}%`);
    } else {
        console.log("No profit, no loss.");
    }
}

3️⃣ Student Pass/Fail Checker 🎓

Determine if a student has passed based on marks in 5 subjects.
Code Snippet:

function Question3() {
    let s1 = 55, s2 = 64, s3 = 75, s4 = 56, s5 = 55;
    if (s1 >= 33 && s2 >= 33 && s3 >= 33 && s4 >= 33 && s5 >= 33) {

5️⃣ Divisibility Check (2 and 3)

Check if a number is divisible by both 2 and 3.
Code Snippet:

function Question5() {
    let num = 6;
    if (num % 2 == 0 && num % 3 == 0) console.log(num + " is divisible by 2 and 3");
    else console.log(num + " is not divisible by 2 and 3");
}

---

6️⃣ Divisibility Check (7 or 3)

Check if a number is divisible by 7 or 3.
Code Snippet:

function Question6() {
    let num = 2;
    if (num % 7 == 0 || num % 3 == 0) console.log(num + " is divisible by 7 or 3");
    else console.log(num + " is not divisible by 7 or 3");
}

---

7️⃣ Positive, Negative, or Zero ➕➖

Check whether a number is positive, negative, or zero.
Code Snippet:

function Question7() {
    let num = 55;
    if (num > 0) console.log(`${num} is Positive`);
    else if (num < 0) console.log(`${num} is Negative`);
    else console.log(`${num} is Zero`);
}

---

8️⃣ Character Type Identifier ✍️

Determine if the given input is an uppercase/lowercase letter, digit, or special character.
Code Snippet:

function Question8() {
    let input = "%";
    let code = input.charCodeAt(0);
    if (code >= 48 && code <= 57) console.log(`Given input is a Digit ${input}`);
    else if (code >= 65 && code <= 90) console.log(`Given input is an Uppercase Character ${input}`);
    else if (code >= 97 && code <= 122) console.log(`Given input is a Lowercase Character ${input}`);
    else console.log(`Given input is a Special Character ${input}`);
}

---

9️⃣ Triangle Validity Check 🔺

Check if the given sides form a valid triangle.
Code Snippet:

function Question9() {
    let a = 30, b = 40, c = 50;
    if ((a + b) > c && (a + c) > b && (b + c) > a) console.log("Given Triangle Is Valid");
    else console.log("Given Triangle is Invalid");
}

---

🔟 Days in a Month Checker 📅

Determine the number of days in a given month.
Code Snippet:

function Question10() {
    let month = 5;
    if (month > 0 && month < 13) {
        if (month == 2) console.log(`${month} Month has 28 or 29 days`);
        else if (month == 4 || month == 6 || month == 9 || month == 11) console.log(`${month} has 30 days`);
        else console.log(`${month} has 31 Days`);
    } else console.log("Invalid Month");
}
