简单的采样，设计一个输入序列，实现其采样，绘出采样后的时域波形(Simple sampling design an input sequence, to achieve its sample, drawn after the time-domain waveform sampling)

program that will calculate how many odd integers in a given interval from 1 to N, where N is entered through the keyboard. The program will print out the total number of odd numbers in a given interval as the product of all odd numbers in that interval. As a result, the program should print "at intervals of 1 to N has <x> odd numbers and their product is <proizvod>.".

关于自适应控制，经过仿真证明可以用，而且比较准确，值得一看。(it is good )
