suppose we want to round all 4-digit integer into 3 digit integers, after checking the fourth digit on right. for example, integer 2343 to be

rounded into 234 while the integer 7887 into 789, since the fourth didgit on right is >=5. write the program needed to repeatdly get a 4 digits integer from the user. stop the processing in the main function when the use provides the integer 99999.
