求大神修改
int getDistance(char s1,char s2)
{  
    int len1,len2;
    len1=strlen(s1);
    len2=strlen(s2);
    int d[len1+1][len2+1];
    int i=0;,j=0;
    for(i=0;i<=len1;i++)
    {
        d[i][0]=i;
    }
    for(j=0;j<=len2;j++)
    {
        d[0][j]=j;
    }
    for(i=1;i<len1+1;i++)
    {
        for(j=1;j<len2+1;j++)
        {
             int cost = 1;  
             if(s1[i-1] == s2[j-1])
             {
                  cost=0;
             }
             int delete=d[i-1][j]+1;
             int insert=d[i][j-1]+1;
             int substitution=d[i-1][j-1]+cost;
             d[i][j]=min(delete,insert,substitution);
        }
        return(d[len1][len2]);
    }
}
int min(int d,int i,int s)
    {
        int temp=0;
        if(d>i)
           temp=i;
         else
           temp=d;
         return s<temp?s:temp;      
    }
main()
{
    char s1[] = {"kitten"};
    char s2[] ={"sitting"};
     printf(getDistance(s1,s2));
}

不知所云

没仔细看你代码，不过有几处错误稍微改了下，你看看可以了么

int getDistance(char s1[],char s2[])
{ 

    int len1,len2;
    len1=strlen(s1);
    len2=strlen(s2);
    int d[len1+1][len2+1];
    int i=0,j=0;
    for(i=0;i<=len1;i++)
    {
        d[i][0]=i;
    }
    for(j=0;j<=len2;j++)
    {
        d[0][j]=j;
    }
    for(i=1;i<len1+1;i++)
    {
        for(j=1;j<len2+1;j++)
        {
             int cost = 1; 

             if(s1[i-1] == s2[j-1])
             {
                  cost=0;
             }
             int delete=d[i-1][j]+1;
             int insert=d[i][j-1]+1;
             int substitution=d[i-1][j-1]+cost;
             d[i][j]=min(delete,insert,substitution);
        }
        return(d[len1][len2]);
    }
}
int min(int d,int i,int s)
    {
        int temp=0;
        if(d>i)
           temp=i;
         else
           temp=d;
         return s<temp?s:temp;     

    }
main()
{
    char s1[] = {"kitten"};
    char s2[] ={"sitting"};
    printf("%d",getDistance(s1,s2));
} 

还是不行
