1.Assume you have a variable declared like this int n=5; When this runs a variable n is created somewhere in memory. Write one line of code that will print out the memory address of n to the console.

2.What does the sizeof function do? Write a few line of codes to show an example of its use, and predict the outcome.

3. Write one line of code that wil declare a variable that is a pointer to a double. Name your variable 'ref'. Then assuming you have already declared and defined a double variable named height, write a second line of code that stores a pointer to height in ref.

4. Continue from the previous problem... Write one line of code that increases the current value stored in height variable by 1.05 without using the height variable name.(Use only the ref variable in your solution. Height = height+1.05 is not allowed.)
