为什么用了strcpy之后会出现乱码

为什么用了strcpy之后会出现乱码

#include<stdio.h>

}
printf("%s\n",TOTAL_STATION);
printf("%s\n",STRATEGY);
printf("%s\n",DISTANCE);
fclose(fp);
return 0;
}

乱码

删除排序可达到想要的结果，但必须排序

我想要达到的结果

字符串比较用 strcmp() 函数，字符串用 “ ” 双引号，修改如下，供参考：

#include<stdio.h>
#include <stdlib.h>
#include <string.h>
int main()

    fscanf(fp,"%s",&canshu2);
    fscanf(fp,"%s",&e);
    fscanf(fp,"%s",&f);
    fscanf(fp,"%s",&canshu3);
    if(strcmp(a,"TOTAL_STATION") == 0)//if(a=='TOTAL_STATION')
    {
       strcpy(canshu1,TOTAL_STATION);
