CString and array.

[Oskar]

Hi.
I`m new in cpp and i have a litlle problem.
i have a CString from Edit Box (eg."aaa bbb ccc 7327373 d feaf 323 dvjiv
234") and i want to put the data (space separated) into an array.It shuld be
somethign like this.

array1[0]="aaa";
array1[1]="bbb";
....
array1[43653]="234";

The thing is i don`t have any clue how to do it. :|

CString is OFF-TOPIC here.

As for an array of strings:

char* p_array_strings[50];

p_array_strings[0] = "Aa";
p_array_strings[1] = "Bb";
p_array_strings[2] = "Cc";
p_array_strings[3] = "Dd";
p_array_strings[4] = "Ee";
p_array_strings[5] = "Ff";

I know how to add data to array, but i need function or smth. that get that
data from CString (separates by spaces) and add it do array.

The CString class is a Microsoft Specialty and best discussed
in a Microsoft newsgroup.

If it were an std::string, you could use the "find" method
to look for spaces.

std::string text;
std::string string_array[43653];

string::size_type position(0);
string::size_type end_posn;

end_posn = text.find(" ", posn);
string_array[0] = text.substr(posn, end_posn - posn);
posn = text.find_firs_not_of(" ", end_posn);
end_posn = text.find(" ", posn);
string_array[1] = text.substr(posn, end_posn - posn);

and so on.

Some suggestions -
1. CString is not a standard C++ class. Use std::string instead (#include
<string>).

string s="abcd efgh ...";

2. Use stringstreams
istringstream istr(s); // Initialize with your string

3. Then don't use arrays, use std::vector class. It's a dynamically growing
array.
vector<string> vec;

4. Extract strings from stringstream.
string temp;
istr >> temp; // temp now contains abcd
vec.push_back(temp); // Push into the vector
istr >> temp; // temp contains efgh
so on...

CString is off topic here. For splitting a std::string, see my example
at

strtok function does what you want.

You haven't defined CString or array1.

So I'll assume:

typedef char CString[80];
CString array1[5];

You can use various tricks for separating-out
space-separated "words". My favorite is a stringstream.
Try something like this:

#include <iostream>
#include <cstring>
#include <sstream>

using std::istringstream;
using std::cout;
using std::endl;

int main()
{
typedef char CString[80];
CString array1[5];
CString string1 = "my red dog is handsome";
std::istringstream blat(string1);
char buffer[65];
for (int i=0 ; i<5; ++i)
{
blat >> buffer;
if (!blat) break;
strcpy(array1[i], buffer);
}
for (int i=0 ; i<5; ++i)
{
cout << array1[i] << endl;
}
return 0;
}

Why not just write a function?

First of all, find out how many spaces there are.
Then define an array via new. Then just take the addresses.
Untest code but you'll get the jist:
char* ReturnStringArray(const char* input_string)
{
size_t length = strlen(input_string);

size_t amount_spaces = 0;

for(size_t i = 0; i < length; ++i)
{
if (input_string[i] == ' ') ++amount_spaces;
}

char* const p_stringarray = new char*[amount_spaces + 1];

p_stringarray[0] = input_string;

unsigned short index = 1;

for(size_t i = 0; i < length; ++i)
{
if (input_string[i] == ' ')
{
p_stringarray[index++] = input_string[i+1];
}
}

p_stringarray[index] = 0;
}
int main()
{
char* p_blah = "aaaa bbbb cccc ffff kkkk";

char* p_stringarray = ReturnStringArray(p_blah);

//Work with it

delete [] p_stringarray;
}
