[填空题]下面的函数strcat(str1，str2)实现将字符串str2拼接到字符串str1后面的功能。请填空使之完整。 char*strcat(str1,str2) char*str1,*str2； { char*t=str1； while( 【16】 )str1++； while( 【17】 )； return(t)；}

[填空题]【说明】
下面的程序功能的功能是以行为单位对字符串按下面的条件进行排序。排序条件为：从字符串中间一分为二，右边部分按字符的ASCII值降序排序，排序后左边部分与右边部分进行交换。如果原字符串长度为奇数，则最中间的字符不参加排序，字符仍放在原位置上
例如：位置：0 1 2 3 4 5 6 7
源字符串：h g f e a b c d
则处理后字符串：d c b a h g f e
