1. Let x and y be double variables that have been defined. Write a statement that displays "x^y = " on the output window followed by the return value from calling the pow() function and passing x and y as the parameters. For example, if x is 3 and y is 4 the output would be "x^y = 81".

2. Let x and y be defined as double variables. Write an expression that will calculate the square root of x^y. Hint: make the return value from pow() the input parameter to sqrt()

3. sqrAndAdd() is a function that has two double parameters and returns the sum of the squares of the parameters (as a double). For example, callingsqrAndAdd(2, 4) would return 2^2 + 4^2 = 20. Let x and y be defined as double variables. Write an expression that will calculate (x^2 + y^2) raised to the fifth power. Hint: make the return value from calling sqrAndAdd() the first input parameter to the pow() function.

4. Write a function definition for a function named  ouch() that has no parameters and returns nothing. When ouch() is called it displays the string literal "Ouch!" on the output window.

Instructor Notes: Remember the syntax for a function definition is:
data-type-return-value name-of-function ( optional-param-list)
{
one-or-more-statements
}

A function that does not return a value is called a void function and in place of the return value data type, we write the reserved word void there.'

5. Write fhe function definition for a function named  outputDottedLine() which has no parameters and returns nothing. When called,outputDottedLine() shall display five consecutive periods ..... on the outupt window followed by a newline.
