用一个整型数组表示一个大数,数组的每个元素储存大数的一位数字,则实际的大数d表示为: d=a[k]*10的k-1次幂+a[k-1]*10的k-2次幂+......+a[2]*10+a[1] 其中a[0]保存该大数的位数．

（２），实现两个大数相乘．

（３），再此基础上实现两个大数相除

-With an integer array to represent a large number, every element of the array storage of large numbers of one digit, the actual large number d is expressed as: d = a [k]* 10 of the k-1 th power+ a [k-1] k-2* 10 plays a power+......+ a [2]* 10+ a [1] where a [0] save the large number of bits. (2), to achieve multiply two large numbers. (3), based on which further divided the two large numbers
