#include<stdio.h>
#include<stdlib.h>
#include<windows.h>
#include<string.h>

char rule1[4][5]={"DCBA","ADCB","BADC","CBAD"},
     rule2[4][5]={"DCAB","ABDC","BDCA","CABD"},
     rule3[4][5]={"DABC","ABCD","BCDA","CDAB"},
     rule4[4][5]={"DACB","ACBD","BDAC","CBDA"}; 
  
void main()
{
    char fun(char b[],int i);
    void moshu();
    char fun(char b[],int i);  //这句声明一下看看
    moshu();

}

void moshu()
{
    char ch[4],an='E';
        int i;
    system("CLS");
    tip2:scanf("%s",ch);
    for(i=0;(i<4)&&(an=='E');i++)
    {
        an=fun(ch,i);
    }
        if(an=='E') 
        {
            printf("输入有问题，请重新输入！\n");
            system("pause");
            system("CLS");
            goto tip2;
        }
  
    printf("%c\n",an);
    system("pause");
}

char fun(char b[],int i)
{
    char bn='E';
    if (strcmp(b,rule1[i])==0)  bn='A';
    if (strcmp(b,rule2[i])==0)  bn='B';
    if (strcmp(b,rule3[i])==0)  bn='C';
    if (strcmp(b,rule4[i])==0)  bn='D';
     
    return(bn);
}

我用的VC6能运行
          输入ABCD 出来C
              BCDA     C
              DCBA     A

Answer 2

把该函数要放到main函数前面
char fun(char b[],int i)
{
char bn='E';
if (strcmp(b,rule1[i])==0) bn='A';
if (strcmp(b,rule2[i])==0) bn='B';
if (strcmp(b,rule3[i])==0) bn='C';
if (strcmp(b,rule4[i])==0) bn='D';

return(bn);
}

追问

还是不对 一样的问题。。。。出现。。。

Answer 3

用strncmp（b,rule1[i]，4）试试
