I am self learning C from the Dietel and Dietel book C How to program. I am doing an assignment at the end of the chapter that requires a user to enter a four digit integer that will be encrypted as follows. Replace each digit with the result of adding 7 to the digit and getting the remainder after dividing the new value by 10. Then swap first digit with third, and second with fourth. Then display the digit. I think I can solve the first part of the problem. I am not sure how I will switch the digits places. Any suggestions is appreciated. So far the material have only covered while loop, if, else if, and I can only use what's available to me up to this point. I look forward to your suggestions. Thank you.</p> c
