本程序中，首先比较输入的a,b的大小，并把大数装入max，小数装入min中，然后再与c比较，若max小于c，则把c赋予max；如果c小于min，则把c赋予min。因此max内总是最大数，而min内总是最小数。最后输出max和min的值即可。-This procedure, the first comparison of the input a, b of the size, and large numbers into the max, a small number of load min, and then compared with c, if the max is less than c, while c given max　if c is less than min, while c given min. Therefore is always within the maximum number max, while the smallest is always within a few min. Finally, the output value of max and min to.
