void tongji(char *s ,char *p)
{
    char *t;
    t=p;
    int n=0;
    while(*s!='\0')
    {
        if(*p==*s)
        {
            while(*p==*s && (*p)!='0')
            {
                p++;
                s++;

            }
        }
        else
            s++;

    printf("%d",n);
}
int main()
{
    char str1[20],str2[10];
    scanf("%s%s",str1,str2);
    tongji(str1,str2);
}


当我输入的子字符串最后出现时候，统计个数总会少1。。。。愁死我了！！

while(*p == *s && (*p) != '\0')

我真是醉了，，谢谢
