Numerical mathematic and computing , c++ programming

Solutions to the following problems should consist of program codes, computed results, and short write-ups. In the write-up, discuss the results you have obtained and explain them from the numerical point of view. Use SINGLE PRECISION ONLY. Insert COMMENTS in your programs. Using a technique explained in the class, calculate the number of mantissa digits and the unit round-off on the machine that you will use for this course. You need to know the number for analyzing errors in this and other home-works and, therefore, I will not be checking your computer projects until you show me a correct solution to this
