C++ Challenges

This is an introduction to how challenges on Edabit work. In the Code tab above you'll see a starter function that looks like this: bool returnTrue() { } All you have to do is type return true; between the curly braces { } and then click the Check button. If you did this correctly, the button will turn red and say SUBMIT FINAL. Click it and see what happens

Create a function that takes two numbers as arguments and returns their sum. Examples addition(3, 2) ➞ 5 addition(-3, -6) ➞ -9 addition(7, 3) ➞ 10 Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Create a function that takes a number as an argument, add one to the number, and return the result. Examples addition(0) ➞ 1 addition(9) ➞ 10 addition(-3) ➞ -2 Notes Do not test for overflow. Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Write a function that takes an integer minutes and converts it to seconds. Examples convert(5) ➞ 300 convert(3) ➞ 180 convert(2) ➞ 120 Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Write a function that takes the base and height of a triangle and return its area. Examples triArea(3, 2) ➞ 3 triArea(7, 4) ➞ 14 triArea(10, 10) ➞ 50 Notes The area of a triangle is: (base * height) / 2 Don't forget to return the result.

Create a function that takes voltage and current and returns the calculated power. Examples circuitPower(230, 10) ➞ 2300 circuitPower(110, 3) ➞ 330 circuitPower(480, 20) ➞ 9600 Notes power is voltage multiplied by current.

Write a function that converts hours into seconds. Examples howManySeconds(2) ➞ 7200 howManySeconds(10) ➞ 36000 howManySeconds(24) ➞ 86400 Notes 60 seconds in a minute, 60 minutes in an hour Don't forget to return your answer.

Create a function that finds the maximum range of a triangle's third edge, where the side lengths are all integers. Examples nextEdge(8, 10) ➞ 17 nextEdge(5, 7) ➞ 11 nextEdge(9, 2) ➞ 10 Notes (side1 + side2) - 1 = maximum range of third edge. The side lengths of the triangle are positive integers. Don't forget to return the result.

There is a single operator in C++, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) ➞ 1 remainder(3, 4) ➞ 3 remainder(-9, 45) ➞ -9 remainder(5, 5) ➞ 0 Notes The tests only us

Fix the code in the code tab to pass this challenge. Look at the examples below to get an idea of what the function should do. Examples squared(5) ➞ 25 squared(9) ➞ 81 squared(100) ➞ 10000 Notes READ EVERY WORD CAREFULLY, CHARACTER BY CHARACTER! Don't overthink this challenge; it's not supposed to be hard.

Create a function that takes length and width and finds the perimeter of a rectangle. Examples findPerimeter(6, 7) ➞ 26 findPerimeter(20, 10) ➞ 60 findPerimeter(2, 9) ➞ 22 Notes Don't forget to return the result. If you're stuck, find help in the Resources tab. If you're really stuck, find solutions in the Solutions tab.

Create a function that takes two integers and checks if they are equal. Examples isEqual(5, 6) ➞ false isEqual(1, 1) ➞ true isEqual(36, 35) ➞ false Notes N/A

Create a function that takes a number as its only argument and returns true if it's less than or equal to zero, otherwise return false. Examples lessThanOrEqualToZero(5) ➞ false lessThanOrEqualToZero(0) ➞ true lessThanOrEqualToZero(2) ➞ false Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're

In this challenge, a farmer is asking you to tell him how many legs can be counted among all his animals. The farmer breeds three species: chickens = 2 legs cows = 4 legs pigs = 4 legs The farmer has counted his animals and he gives you a subtotal for each species. You have to implement a function that returns the total number of legs of all the animals. Ex

Create a function that returns true when num1 is equal to num2; otherwise return false. Examples isSameNum(4, 8) ➞ false isSameNum(2, 2) ➞ true isSameNum(2, "2") ➞ false Notes Don't forget to return the result.

Create a function that reverses a boolean value. Examples reverse(true) ➞ false reverse(false) ➞ true Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab. If you're really stuck, unlock solutions in the Solutions tab.

Fix the code in the Code tab so the function returns true if and only if x is equal to 7. Try to debug code and pass all the tests. Examples isSeven(4) ➞ false isSeven(9) ➞ false isSeven(7) ➞ true Notes The bug can be hard to find, so look closely!

Given two numbers, return true if the sum of both numbers is less than 100. Otherwise return false. Examples lessThan100(22, 15) ➞ true // 22 + 15 = 37 lessThan100(83, 34) ➞ false // 83 + 34 = 117 lessThan100(3, 77) ➞ true Notes N/A

Write a function that takes two integers (hours, minutes), converts them to seconds, and adds them. Examples convert(1, 3) ➞ 3780 convert(2, 0) ➞ 7200 convert(0, 0) ➞ 0 Notes Don't forget to return the result. If you get stuck on a challenge, find help in the Resources tab.

Create a function that converts inches to the number of complete feet, ignoring any leftover inches. Examples inchesToFeet(324) ➞ 27 inchesToFeet(12) ➞ 1 inchesToFeet(36) ➞ 3 Notes If inches are under 12, return 0. 12 inches = 1 foot.
