Problems with array of strings

Hello,
I would like to as how shoul i input strings into array from keyboard?

Thanks in advance.

my code is:

Code:

---

#include <stdio.h>

void main () {

 char *string[3];
 int i;

 for(i=0;i<3;i++)
    scanf("%s",&string[i]);

 for(i=0;i<3;i++)
      printf("%s",string[i]);

}

---

:confused:

Firstly, don't use void main, use int main.
Secondly, you must have some sort of space to store the strings. Simply defining a pointer will not give you space. You have to manually call malloc and later free to do that. Or you can simple use an array.

char string[3][100];

Or the like.
This is very important. Be very careful when using scanf to read strings. Read this for more information:

probably char string[3][100] to have 3 strings of 100 bytes each

Right. Good correction. Not used to 2D arrays, since I hardly need them in C++...

ok, i tired to correct mistakes.. but..there are some left..

Code:

---

#include <stdio.h>

int main () {

        char string[3][100];
        int i, j;

        j=0;
                while (j<4)
                {fgets(*string,100,stdin);
            for(i=0;i<100;i++)
                        {if(string[j][i]=='\n')
                                {string[j][i]='\0';
                            j+=1; break;}}
        return 0;

Erm. This will fail to compile in every sort of way.
You need to learn indenting. You can use an auto-indenting IDE such as Visual Studio or Code::Blocks if on Windows.
And as for the fgets... do you know how arrays work?

1. indentation
2. you should update different strings
3. use for loop

Code:

---

for(j=0;j<3;j++)
{
  fgets(string[j], sizeof string[j], stdin);

no..i'm new to C.. that's why i'm having problems with such a simple task :(

Thanks very much, i did it (atctually you did it) ;) I had some practice programing with Delphi, but it's much easier to work with strings there :)

And the other thing i wanted to ask what should i do, if i need other chars, which are not stored in ANSI C, for example Russian.

If you want to attempt non-english languages, I suggest you use unicode or wide char.
Usually denoted by wchar_t instead of char.
Wide strings also uses an L before the string, so "My string" would be come L"My string".
You also need to use appropriate library functions. But they should all be available in documentation if you need to find them.

But if I need to save all Russian chars, isn't it possible to set whole language alphabet somehow, using UTF-8 locale?

I imagine it might be, but code locales isn't directly my area.
If you use wide chars, you don't really have much about code locales to worry about. Or, at the very least, less to worry about.

So if I'll try to solve this problem using wide chars, I should define every char, which isn't included to ANSI C?

You do have russian encoding in ANSI - like Windows(Cyrillic), KOI-8 or ISO(Cyrillic) or DOS(Cyrillic)

You will have encoded russian chars in the codes from 128 to 255 (using different tables for each of the above) - and be able still work with the standard string functions

If you go for the wide char encoding - you will need to change the type od the string to wchar
and the function used to the w-version
