C++解答

#include <cstdio>
#include <cstring>

int main() {
    //freopen("test.in", "r", stdin);
    //freopen("test.out", "w", stdout);
    int cnt = 0;
    char s[100];
    while (scanf("%s", s)) {
        if ('0' == s[0]) break;
        ++cnt;
        if (cnt > 10) break;
        printf("%s ", s);
        int n = strlen(s), x = 0;
        for (int i = n - 1; i >= 0; --i)
            x = x * 10 + (s[i] - '0');
        printf("%d\n", x);
    }
    return 0;
