strlen(s)返回字符串s的长度，char *p = s;char *q = s + strlen(s)-1;这两句执行完成后，p指向字符串的首地址，q指向字符串的末地址。p++是指针后移，q--是指针前移。为的是交换p、q指向的字符。实现的效果是把字符串反转了。

1以下函数实现的功能是void fun (char *s) char *p,*q,temp; p=s; q=s+ strlen(s)-1; while (p<q) temp=*p; *p=*q; *p=temp; p++; q--; A.将一个字符串首尾颠倒B.计算字符串的长度C.统计字符串中的空格个数D.将字符串中的小写字母变成大写字母 2以下函数实现的功能是( )...

Sets this string to str, interpreted as a classic 8-bit ASCII C string. If len is -1 (the default), then it is set to strlen(str). If str is 0 a null string is created. If str is "", an empty string is created. See
