求KMP算法的实现C或C++程序与KMP算法中求NEXT【】的C或C++程序

#include<stdio.h>
#include<string.h>
#define NOTFOUND -1
#define ERROR -2
#define MAXLEN 100  
char S[MAXLEN+10],T[MAXLEN+10],st[MAXLEN+10];   
int S0,T0;                                      
int pos;                                       
int next[MAXLEN+10];
void Init(char *S,int &S0)
{
    int len,i;
    New_Input:
    scanf("%s",st);
    len=strlen(st);
    if (len>MAXLEN)
    {
        printf("This String is too long,Please Input a new one.\n\n");
        goto New_Input;
    }
    for (i=1;i<=len;i++) S[i]=st[i-1];
    S[len+1]='\0';
    S0=len;
}

void Get_next(char *S,int *next)
{
    int i=1,j=0;
    next[1]=0;
    while (i<T0)
        if (j==0 || T[i]==T[j])
        {i++; j++; next[i]=next[j];}
        else j=next[j];
}

int Index_KMP(char *S,char *T,int pos)
{

    int i=pos,j=1;
    while (i<=S0 && j<=T0)
        if (j==0 || S[i]==T[j])
        {i++; j++;}
        else j=next[j];
    if (j>T0) return i-T0;
   else return NOTFOUND;
}
int main()
{
    int ret;//函数返回值
    Init(S,S0);
    Init(T,T0);
    scanf("%d",&pos);
    Get_next(T,next);
    ret=Index_KMP(S,T,pos);
    if (ret==NOTFOUND) printf("Not Found.\n");
    else if (ret==ERROR) printf("The Input Data is Error.\n");
    else printf("In S,from %dth is equal to T.\n",ret);
    return 0;

}

求next的值的程序，要求有输出next的值在屏幕上输出的哦

wo 我的问题还没解决呢！！
