char array of words

Hi,I wanted to have a array for char words. That is have a list of words like one two three

So, tried

Code:

---

char *num[]={"One","Two","three"};

---

And it works fine. But later I wanted to assign the char words manually.So i tried the following,but it fails to work.

Code:

---

  char *num[5][10];
 
  strcpy("one",num[0]);
  strcpy("two",num[1]);
  strcpy("three",num[2]);

---

dunnno if its coding error or wrong methodolgy(if wrong do tell me correct one.thanx).

You've got the order of the arguments to strcpy wrong. Also, num shouldn't be a 2-D array of pointers in this case:

Code:

---

char num[5][10];
 
strcpy(num[0],"one");
strcpy(num[1],"two");
strcpy(num[2],"three");

---

Since this is the C++ board, maybe you should try an array or vector of strings:

Code:

---

vector<string> strVect;

strVect.push_back("one");
strVect.push_back("two");
strVect.push_back("three");

although vector is much convenient that array, arrays offer much more functionality and push you to your limits.

aren't chars contained in single quotation marks ??
'char' ??
, note: I did not compile this code, it's just for demonstration

Code:

---

char* charArray[5];
for(int i = 0; i < 5; i++)
charArray[i] = new char;

*charArray[0] = 'H';
*charArray[1] = 'E';
*charArray[2] = 'L';
*charArray[3] = 'L';
*charArray[4] = 'O';

//Deleting
for(int i = 0; i < 5; i++)
delete[] charArray[i];
charArray[i] = 0;

corrected :)

How on earth do arrays offer more functionality than vectors?

delete[] is for new[]

you have new char - it sould be deleted with regular delete

Besides the fact that vectors let you do anything that arrays do (often more easily and just as efficiently - assuming you use reserve() and/or resize() to avoid unnecessary reallocation when you know in advance an upper bound for the size), you don't WANT to be pushed to your limits by an unnecessarily limited programming language (otherwise, why not use assembly?), but by choosing harder problems to code. Features like vectors let your limits go farther.
