My code is:

#include <iostream.h>
#include <ctype.h>
#include <vector>
#include <conio.h>

#include <string.h>

using std::vector;
using std::string;

std::vector<char *> nocode;
std::vector<char *> code;
std::string input("");

char inputs[500];
char y_n;
int x;

void encode();

int main()
{
	do{
		cout << "Input the line:" << endl;
		cin.ignore(80, '\n');
		cin.getline(inputs, 60);
		cin.ignore(80, '\n');
		input=inputs;
		

		cout << endl;
		cout << input << '\n';

		system("CLS");

		cout << "Unencrypted:\n";
		cout << input;

		encode();

		cout << "Encrypted:\n";
		cout << input;

		input="";
		cout << "Do another line? (y/n)";
		cin >> y_n;
	}while(tolower(y_n)!='n');
	return 0;
}


void encode()
{
	for(int x=0; x<int(input.size); x++)
	{
		if(toupper(input[x])=='A'||toupper(input[x])=='E'||toupper(input[x])=='I'||toupper(input[x])=='O'||toupper(input[x])=='U')
		{

			if(input[x]<65)
			{

			{

		else

My errors are
"error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptable conve"

I have three of them, every time I try to output the string input. I can't use getline to receive "input," just as an addendum. Anybody know why I'm getting these errors? it's been almost an hour now and I still can't figure it out.

EDIT: it's lines 32, 37, and 42

I wonder if this has to do with using std::string mixed with iostream.h's cout...

The preferred headers are #include <iostream> , etc. (without the .h). Then to bring each unknown symbol into scope you can use using std::symbol; or using namespace std; to bring them all in.

[Lowest0ne]

To add, you would need at least:

using std::cin;
using std::cout;
using std::endl;

I've also been a little confuse with std::string, I don't think this is the same type of string one gets when he/she includes <string>, but I could be wrong. I don't really understand why you extract a char array and then convert it to a string, but that is another story.

Whoa whoa whoa whoa whoa ...

I've seen so many people use #include <iostream.h> , when iostream.h is obselete. Use iostream (no extension) instead. Same with #include <string.h> and #include <string> , don't use the extension.

[NerdTastic]

MSVC++ 6.0 Enterprise does not have iostream. This comes up every time. it uses non-standard headers. Today I gave up and switched to code::Blocks. Will keep you updated.

x<input.size

I'm being told that's illegal... x is of int type, and input is a string. Any ideas? I've tried typecasting (in fact I think it's typecasted above) but that didn't help.

Exact error:

error: invalid use of member (did you forget the '&'?)

do i need an &?

x < input.size()

'Preciate it.

[NerdTastic]

Is there any std::string equivalent for the cstring spanexcluding() function? I used the same thread because it's for the same program.

[moorecm]

What does it do?

Hello everyone

I am not a programmer.
I was running a data analysis software for ecology and there was the following debug error:
heap corruption detected: before normal block (#271) at 0x026A8C68
Do you think I can ignore the error? what I have to resolve this?
The problem does not occurs with all .txt files with data which I import to the software. Only for some .txt.
Thank you very much
Regards
Jose

No. Heap errors need addressing as soon as they arise. I recommend reporting the error to the developers so that they can home-in on the issue. Be sure to provide a detailed report.

Are the troublesome text files of a large capacity (2:4GB+)?

[macedo]

Thanks for the help
Who are the developers (C++ or from the software)?
The text files are of very small size

regards
Jose

[zb0S216C]

Send it to the developers of the software. As for your files, perhaps there data inside the file has the wrong format? Without a sample of the file, it's difficult to determine.

I don't want us to hijack this thread, so create a new discussion and we'll go from there.

Err... bump? lol

@moorecm it returns a substring that cuts out all of a character, for example

Cstring str("Hello Test");
Cstring stri;


stri=str.spanexcluding(" ");

stri would then be equal to "HelloTest".

EDIT: for any who just joined this thread, the question is are there any std::string equivalents for the cstring spanexcluding() function

[moorecm]

http://cplusplus.com/reference/algorithm/remove/
http://cplusplus.com/reference/string/string/erase/

Something like this:

string str( "Hello Test" );
str.erase( remove( str.begin(), str.end(), ' ' ), str.end() );
cout << str << endl;

[NerdTastic]

Would that work for more than one space?
i.e. "Hello This Is A Test"

[Whovian]

Test it!

[NerdTastic]

you rock.
