Only the user must enter any values (a, b, c, alpha, beta, gamma).
Then the program will calculate the angles and sides.
At the end of a table is now to be issued, which shows all six values.
You should write a little more info for example what you mean by a b c and alpha beta gamma. i suppose abc are the sides and alpha beta gamma are the angles. Which of the following will the user have to enter? Because if he specifies each one of them there is nothing to calculate.
