Create a basic program that accomplishes the following requirements: Allows the user to input 2 number , a starting number x and
katrin [286]

Answer:

Explanation:

The following program is written in Java. It asks the user for the two inputs and then uses those inputs in a for loop. The loop goes through each number checking to see if it is even or odd. If it is even it prints out Even: and the number after multiplying it by 3. If it is odd it prints out Odd: and the number after adding 10 to it. The output can be seen in the attached picture below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter number 1: ");

       int num1 = in.nextInt();

       System.out.println("Enter number 2:");

       int num2 = in.nextInt();

       for (int x = num1; x <= num2; x++) {

           if ((x % 2) == 0) {

               System.out.println("Even: " + (x*3));

           } else {

               System.out.println("Odd: " + (x+10));

           }

       }

   }

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance
Stels [109]

Answer:

#include <stdio.h>

int main()

{

float your_value1, your_value2, your_value3, your_value4, your_value5;

printf("Enter a frequency: ");

scanf_s("%f", &your_value1);//storing initial key frequency in your value 1

 

float r = 2.0 / 12;//typing 2.0 so it is treated as float and not int

your_value2 = your_value1 * r * 1; //initial*r*n

your_value3 = your_value1 * r * 2; //initial*r*n

your_value4 = your_value1 * r * 3; //initial*r*n

your_value5 = your_value1 * r * 4; //initial*r*n

printf("%0.2f %0.2f %0.2f %0.2f %0.2f", your_value1, your_value2, your_value3, your_value4, your_value5);

return 0;

}

Explanation:

The purpose of this exercise is to make you understand the difference between float and int. float variables are used when you need decimals in your calculations. int is used when you need integers. The problem in this exercise was the formulation of r. Now r is = 2/12, this means that when we type r as that, the computer assumes that it is an integer and treats it as such. So, it will convert the 0.166667 into 0. To overcome this, all you have to do is type 2.0 instead of 2 alone.

The %0.2 command restricts the float variable to 2 decimal places. By default, it has 6 decimal places.

I have used the function scanf_s instead of scanf simply because my compiler does not work with scanf.
