Here is how to do exponentiation asking the user for two numbers:

The program should ask the user for two numbers “a” and “b”, and then, raise “a” to the power of “b”. In order to do this, we will be using 4 variables:

• long a;
• long b;
• long power=1;
• long counter=0; 

We will be using a “do, while” loop, therefore, we need a variable to use as a counter and asign to it the value of 0. 
After asking the user for both numbers a and b, you will create a “do while” loop that works (while counter < b), because we will need the loop to work until we get to the value of b.

Lets remember the formula for exponentiation:   photo by:  http://en.wikipedia.org/wiki/Exponentiation

Our do while loop, will multiply “a”, “b” times, which means that the loop should multiply “a x a” as many times as the variable “b” states.

Here is how it should look:

  do{

power=power*a;

counter=counter+1;

       }while(counter < b); 

After that you can print out the new value of your variable “power” in order to show your result. 

Here is a picture of the code and how it should run:
