Answer:
Explanation:
The following code is written in Python. It prompts the user for the name and age, saves them to their own variables. Then it creates and calculates the dogAge variable. Finally, it combines all of this information and prints out the statement.
name = input("Enter your name: ")
age = input("Enter your age: ")
dogAge = int(age) * 7
print("Your name is", name, "and in dog years you are", dogAge, "years old.")
Answer:
Here is the JAVA program:
import java.util.Scanner; //to take input from user
public class Main{
public static void main(String[] args) { //start of main function
Scanner input = new Scanner(System.in); // creates Scanner class object
int num, integer, odd = 0, even = 0; //declare variables
System.out.print("Enter the number of integers: "); //prompts user to enter number of integers
num = input.nextInt(); //reads value of num from user
System.out.print("Enter the integers:\n"); //prompts user to enter the integers
for (int i = 0; i < num; i++) { //iterates through each input integer
integer = input.nextInt(); // reads each integer value
if (integer % 2 == 0) //if integer value is completely divisible by 2
even += integer; //adds even integers
else //if integer value is not completely divisible by 2
odd += integer; } //adds odd integers
System.out.print("Sum of Even Numbers: " + even); //prints the sum of even integers
System.out.print("\nSum of Odd Numbers: " + odd);//prints the sum of odd integers
}}
Explanation:
The program is explained in the comments mentioned with each line of the code. I will explain the logic of the program with the help of an example.
Suppose user wants to input 5 integers. So,
num = 5
Suppose the input integers are:
1, 2 , 3, 4, 5
for (int i = 0; i < num; i++) is a for loop that has a variable i initialized to 0. The condition i<num is true because i=0 and num=5 so 0<5. Hence the statements inside body of loop execute.
At first iteration:
integer = input.nextInt(); statement reads the value of input integer. The first integer is 1
if (integer % 2 == 0) checks if integer is completely divisible by 2. The modulo operator is used which returns the remainder of the division and if this remainder is equal to 0 then it means that the integer is completely divisible by 2 and if the integer is completely divisible by 2 then this means the integer is even. 1%2 returns 1 so this means this condition evaluates to false and the integer is not even. So the else part executes:
odd += integer; this becomes:
odd = odd + integer
odd = 1
Now the value of i is incremented to 1 so i=1
At second iteration:
integer = input.nextInt(); statement reads the value of input integer. The first integer is 2
if (integer % 2 == 0) checks if integer is completely divisible by 2. 2%2 returns 0 so this means this condition evaluates to true and the integer is even. So
even += integer; this becomes:
even= even+ integer
even = 2
Now the value of i is incremented to 1 so i=2
At third iteration:
integer = input.nextInt(); statement reads the value of input integer. The first integer is 3
if (integer % 2 == 0) checks if integer is completely divisible by 2. 3%2 returns 1 so this means this condition evaluates to false and the integer is odd. So
odd += integer; this becomes:
odd= odd + integer
odd= 1 + 3
odd = 4
Now the value of i is incremented to 1 so i=3
At fourth iteration:
integer = input.nextInt(); statement reads the value of input integer. The first integer is 4
if (integer % 2 == 0) checks if integer is completely divisible by 2. 4%2 returns 0 so this means this condition evaluates to true and the integer is even. So
even+= integer; this becomes:
even = even + integer
even = 2 + 4
even = 6
Now the value of i is incremented to 1 so i=4
At fifth iteration:
integer = input.nextInt(); statement reads the value of input integer. The first integer is 5
if (integer % 2 == 0) checks if integer is completely divisible by 2. 5%2 returns 1 so this means this condition evaluates to false and the integer is odd. So
odd+= integer; this becomes:
odd= odd+ integer
odd= 4 + 5
odd = 9
Now the value of i is incremented to 1 so i=5
When i=5 then i<num condition evaluate to false so the loop breaks. The next two print statement prints the values of even and odd. So
even = 6
odd = 9
Hence the output is:
Sum of Even Numbers: 6 Sum of Odd Numbers: 9
