In that case we want to normalize it to 0 so all grades fall into the range [0, 100]. ex: bound_0_to_100(75) returns 75, bound_0_to_100(103) returns 100, and bound_0_to_100(-5) returns 0arrow_forward
- 5. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how- ever, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime. 6. In another program, use the function you wrote in question 5 to print the prime numbers between 1 and 100 using for loop.arrow_forwardLucky Customer Code in C Languagearrow_forwardCoin Toss Write a function named coinToss that simulates the tossing of a coin. When you call the function, it should generate a random number in the range of 1 through 2. If the random number is 1, the function should display "heads". If the random number is 2, the function should display "tails". Demonstrate the function in a program that sks the user how many times the coin should be tossed and the coin then simulates the tossing of the coin that number of times.arrow_forward
- Convert totalMeters to hectometers, decameters, and meters, finding the maximum number of hectometers, then decameters, then meters. Ex: If the input is 815, then the output is: Hectometers: 8 Decameters: 1 Meters: 5 Note: A hectometer is 100 meters. A decameter is 10 meters. 1 #include 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13 14 15 16 17 18 int totalMeters; int numHectometers; int numDecameters; int numMeters; cin >>totalMeters; cout << "Hectometers: cout << "Decameters: cout << "Meters: " << numMeters << endl; " << numHectometers << endl; << numDecameters << endl; 2 3arrow_forwardint func(int a, int b) { return (aarrow_forwardWrite the following function to display three numbers in increasing order:def displaySortedNumbers(num1, num2, num3):Write a test program that prompts the user to enter three numbers and invokes the function to display them in increasing order.arrow_forwardAssignment Write a program that tracks how much steps the user walks in total in a day and reports if the daily target is reached or not. The program will keep reading double values, each representing steps walked during an individual activity within a day (stepsWalked) until either the user enters a negative value or the daily target of 5000 steps is met. If the user enters a negative number, the program should print total steps walked as a double. Otherwise, if the target is exactly reached, the program should simply print "Target is reached", finally if the target is surpassed the program should print the text "Target is surpassed by", followed by the excess amount above the target as a double, and finally printing the text "steps". NOTE: YOU MUST use a repetitive statement in this question. NOTE: Each stepsWalked value will be given as a non-negative value. You do NOT need to check this.
