一个多位数逆置

#include <stdio.h> int main() { //一个多位数逆置 int n = 0; scanf("%d",&n); int b = 1, ans = 0; int flag = 0; while (n!=0){ int k = n % 10; n /= 10; if (k == 0 && flag == 0){ flag = 1; ans = ans * 10; } else if (k == 0 && flag == 1){ continue; } if (k != 0){ ans = ans * 10 + k; flag = 0; } } printf("%d\n",ans); return 0;
