主题：【原创】如何REVERSE一个C STRING? -- 老成都

you need to pass a char[], you can not pass "hello the world" directly, you need to scan a string to a char buffer.

My environment is gcc/Linux.

Do you kown the difference for "char *p="hello the world" and the "char p[100]"?

My test code is something like

"

main()

{

char str[100],

scan("%s",str);

printf("original:%s\n",str);

reverse(str);

printf("reversed:%s\n",str);

}

"

It works fine. I guess you pass "hello the world" directly into the reverse function.
