• You cannot define a new variable inside a loop (i.e. String s defined in the while loop.)

• Variables defined in a while loop cannot be accessed outside the loop (String s variable is used outside the while loop.)

• You cannot use a variable in the loop when the variable is defined outside the loop (i.e. int count is defined outside the loop, but used/incremented inside the loop)

• No error in the code
