本实验要求通过求某数据区内负数的个数来表现循环程序的结构形式。要求实验程序在数据区中存放一组数据，为统计负数的个数，逐个判断区内的数据，然后将所有数据中凡是符号位为1的数据的个数累加起来，即得到区内所包含负数的个数-This experiment requires a data region by calculating the number of negative performance cycle to structure the program. Experimental procedures required in the data storage area of a set of data, as the number of negative statistics, one by one to determine the area of data, and then sign all the data in any data bit is 1, add up the number that are contained by the region the number of negative
