Hi,

I wrote a palindrome code in C++, and got a few errors that I can not figure it out. I'm suppose to write the palindrome program and "erase the spaces betweeen words".

*snip*

The line in bold is the problem,

Thanks,

Doug

There were four or fives lines bolded, can you post the one that you think is the problem, and how you know it's the problem (ie - the error message, or a description of what the output is doing that is incorrect)?

[RedSon]

If this is a homework question it should be treated as such. Is this palindrome code part of your assignment?

Also dougg your thread title is unacceptable per the posting guidelines. Please read the FAQ located in the Tabs above and pay particular attention to http://www.thescripts.com/forum/faq....d_thread_title

Sorry for the title.
This is part of my hw, but i already included the code. I just need to know what is the error. I forgot to include the error message;
Here it goes:

c:\documentos\p rogramas\palind rome\palindrome \palindrome\pal indrome.cpp(77) : error C2228: left of '.length' must have class/struct/union
c:\documentos\p rogramas\palind rome\palindrome \palindrome\pal indrome.cpp(78) : error C2109: subscript requires array or pointer type
c:\documentos\p rogramas\palind rome\palindrome \palindrome\pal indrome.cpp(79) : error C2228: left of '.erase' must have class/struct/union

So those are the error messages, and here are the lines:

for (int i = 0; i < s.length(); i++)
if (s[i] == ' ')
s.erase(i, 1);

Thanks again

No problem its just a warning so that you will be better prepared for the future. Also, please read the posting guidelines in the FAQ, for homework assignments we limit code to just the lines that are causing the problem. What you have copied above is fine.

Please give us the declaration for what s is. If its String s, then it should be String s = new String(); before you can start doing operations on it.

[sicarie]

s was declared int.

[d0ugg]

s = space between words.

please let me know if you have any other question

No problem its just a warning

The compiler clearly did say "error" instead of "waring" in its diagnostic message
though.

kind regards,

Jos

ps. not surprising because that 's' identifier was defined to be of type int.

Either you are trying to make a joke or you misunderstand me. I wasn't referring to the compiler problems.

[RedSon]

s was declared int.

if s is an int you cannot do things like s.length or s[i] those are undefined for type int.
