剑指offer 打印1到最大的n位数

#include <iostream>#include <string.h>#include <stdlib.h>using namespace std;void PrintMaxN(char* num){int flag = 1;int len = strlen(num);for (int i = 0;i<len;i++){if (!(num[i] - '0') && flag)      continue ;else {            printf("%c",num[i]);flag = 0;}}printf("\t");}bool increase(char* num){int conver=0;int len = strlen(num);num[i] += 1;for (int i = len -1;;i>=0;i--){conver = num[i] - '0';if (conver >= 10){if (i == 0)return false;num[i] = '0';num[i-1] += 1;}else return true;}}void OneToMaxN(int n){if (n<=0)        return;char* num = new char[n+1];memset(num,'0',n);num[n] = '\0';while (increase(num)){PrintMaxN(num);}delete []num;}

需要考虑大数问题
