int i,weiqu[1000]={0},j,temp;
     char m;
     printf("请输入万能密码:");
     scanf("%s",&m);
     if (strcmp(m, '000086') == 0)
这个一直显示是编译错误，不知道为什么。
求大佬帮帮忙吧！！！
完整代码如下：
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
void save(int n,int mima,int bianhao);
void get(int n,int *key,int *key1);
void wanneng(int n);

    printf("寄存箱总数:");
    scanf("%d",&n);
    for(i=0;i<=n;i++)
         {
             key1[i]=key[i]=1000+2*i;
         }
    while((choice=inputchoice())!=0){
              switch(choice){

              save(n,mima,bianhao);
              break;
case 2:                     
              get(n,key,key1);

     if (strcmp(m, '000086') == 0)

             else    break;
          }
          printf("是否有物留存");
     }
 }

if (strcmp(m, '000086') == 0)
字符串用双引号

char m;    m应该定义为一个字符串
printf("请输入万能密码:");
scanf("%s",&m);
