高精度

高精度：编程题高精度又该额怎么解答呢？希望下面的文章对大家有所帮助。

#include
#include
#define MAXN 510
using namespace std;

int s1[MAXN];
int s2[MAXN];

void high_plus(string a, string b)
{
    int la = a.length(), lb = b.length();
    int max = la > lb ? la : lb;
    for(int i = 1; i <= la; i ++)
        s1[i] = a[la - i] - '0';
    for(int i = 1; i <= lb; i ++)
        s2[i] = b[lb - i] - '0';
    for(int i = 1; i <= max; i ++)
    {
        int t = s1[i] + s2[i];
        if(t < 10) s1[i] = t;
        else
        {
            s1[i] = t - 10;
            s1[i + 1] ++;
        }
    }
    if(s1[max + 1] != 0) cout << s1[max + 1]; 
    for(int i = max; i >= 1; i --)
        cout << s1[i];
    cout << endl;   
}

int main()
{
    string a, b;
    while(cin >> a >> b)
        high_plus(a, b);
    return 0;
}
