解题思路:

注意事项:

参考代码:

#include<stdio.h>
#include<string.h>
int main()
{
   char a[10],b[10];
   int c,d,i,f=0,e=0;
    scanf("%s%s",a,b);
    c=strlen(a);
    d=strlen(b);
    if(c!=d)
    {
        printf("1");
    }
    else
        {
            for(i=0;i<c;i++)
            {

                if(a[i]+32==b[i]||a[i]==b[i]+32)
                {
                    f=1;
                    continue;
                }
                else if(a[i]==b[i])
                {

                    e=1;
                    continue;
                }
                else
                    {
                        f=0;
                        break;
                    }
            }
            // printf("**********%d",f);
            if(f==1&&e==1)
            {
                printf("3");
                return 0;
            }

            f=1;
            for(i=0;i<c;i++)
            {
                if(a[i]==b[i])
                {
                    continue;
                }
              else
                    {
                        f=0;
                        break;
                    }
            }
                    // printf("************%d",f);
            if(f==1)
            {
                printf("2");
                return 0;
            }

            else
           {printf("4");}

    return 0;
}
