Assistant Teacher Hello: for the second homework this calculator, I spent four days of time, did n times, due to my foundation is too poor, I have to maximize in the console to be able to randomly generate numbers, and four algorithm, (I can do the maximum) and the difficulty is that I can not let users of the four algorithm to calculate the results, Not to mention the correct rate, and it does not recognize division when the divisor cannot be zero. In the form program I made out of the form frame, but I wrote the code after I found TextBox1 and TextBox2 unexpectedly do not produce numbers randomly, I also like most classmates, according to the textbook example to make changes, but I am not as others, I did not use the form to complete, And in the form I can't let the user choose an operation method, also, in the division, the divisor is zero is also a point of my headache. I hope the teacher can give me some guidance and finish the homework better. Teacher, I have been working hard to review the C # language, I hope that you help me in the days ahead can be improved,
For the second assignment does not understand the place
