Practice set on Loops and Functions in JavaScript

//Practice set of Loops and Functions

//Question 1 : Write a program to print the marks of a student in an object using for loop

let marks = {

    harry: 90,

    shubham: 9,

    lovish: 56,

    Monika: 4

}

for (let i = 0; i < Object.keys(marks).length; i++) {

    console.log("The marks of " + Object.keys(marks)[i] + " are " + marks[Object.keys(marks)[i]]);

}

//Question 2 : Write a program in Question 1 using for in loop

for (let key in marks) {

    console.log("The marks of " + key + " are " + marks[key]);

}

//Question 3 : Write a program to print "try again" until the user enters the correct number

let cn = 43;

let i;

while (i != cn) {

    console.log("Try again");

    i = prompt("Enter a number : ");

}

console.log("You have entered a correct number");

//Question 4 : Write a function to find mean of 5 numbers

let p = prompt("Enter the value of a :");

p = Number.parseInt(p);

let q = prompt("Enter the value of b : ");

q = Number.parseInt(q);

let r = prompt("Enter the value of c : ");

r = Number.parseInt(r);

let s = prompt("Enter the value of d : ");

s = Number.parseInt(s);

const mean = (a, b, c, d) => {

    return (a + b + c + d) / 4;

}

console.log(mean(p, q, r, s));
