Please explain the difference between a For Loop and a While Loop.

A while-loop loops as long as it's predicate (the expression in the braces following the while-keyword) is true:

bool keepRunning = true;
while(keepRunning)
{
   // do something

   if(! UserWantsToKeepRunning()) // imagine some user input
      keepRunning = false;
}

A for-loop usually (as a beginner you shouldn't care about non-standard uses yet) increments or decrements a variable with a given starting-value on each loop until the variable reaches a value so that the predicate of the for-loop is no longer true:

// starts with x = 0
// increments x each loop by 1
// when x = 10, x < 10 becomes false, loop ends
for(int x = 0; x < 10; x++)
{
}

You usually use a for-loop if you need a variable running from a start value to an end value and a while-loop if you don't know when writing the code how many loop-runs will be required when your program is executing.

It's easy to "emulate" a for-loop with a while-loop (just an academic example, no real use):

int x = 0;
while(x < 10) // will evaluate to false as soon as x == 10
{
   x++;
}
// when reaching this point, x == 10
