{

void myMethod( )

{

int num1, num2, num3, sum ;

num1 = 250 ;

num2 = 100 ;

num3 = 350 ;

sum = num1 + num2 + num3 ;

System.out.println(" 3 given numbers are: ");

System.out.println( num1 ) ;

System.out.println( num2 ) ;

System.out.println( num3 ) ;

System.out.println( " Sum = " + sum ) ;

}

}

Output:

Answer 2

1. ## I'm using Python language.
2. ## This is a simple question so let's add some functions.
3. ## For defining a function we use "def <name_of_function>():"
4. def Sum(): ## I'm naming the function Sum().
5.    SUM = a[0]+a[1]+a[2] ## Taking a variable SUM for storing the added values.
6.    print ("The sum of {0}, {1} and {2} is {3}.".format(a[0],a[1],a[2],SUM)) ## This will print the last line for the code.
7. ## I'm going to create 2 lists a, and b.
8. a=[0,0,0] ## This list is having temporary values. The value will change in the for loop.  
9. b=["first","second","third"]
10. for i in range(0,3): ## for loop for asking the numbers that is to be added.  
11.    a[i]=int(input("Enter the {} number : ".format(b[i])))  
12. Sum() ## This is used to call the function.
