Answer:
The complete program is as follows:
m_str = input('Input m: ')
mass = float(m_str)
e = mass * 300000000**2
print("e = ",e)
Explanation:
This is an unchanged part of the program
m_str = input('Input m: ')
This converts m_str to float
mass = float(m_str)
This calculates the energy, e
e = mass * 300000000**2
This is an unchanged part of the program
print("e = ",e)
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String name;
System.out.print("First name: ");
name = input.next();
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
System.out.print(name);
}
}
Explanation:
This declares name as string
String name;
This prompts the user for first name
System.out.print("First name: ");
This gets the name from the user
name = input.next();
This capitalizes the first letter of name and makes the other letters to be in lowercase
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
This prints the formatted name
System.out.print(name);
