Thread: pointer to array as parameter to function

Hi,

I wrote a simple program that counts the letters in the words from a sentence.
The program works, but what i was wondering is :
did i use the correct approach to pass the pointers to the function bereken. Also with a pointer to an array, do you have to de-reference this pointer (in the function bereken) ? I just used the name without de-referencing, this seems to work.

Thanks.

Code:

#include <iostream.h>
#include <string.h>

void bereken(char *zinp, int *letters);

void main()
{
	char zin[80];
	int letters[10];
	int i;

	//clrscr();
	cout << "Geef een nieuwe regel: ";
	cin.getline(zin,80);

	cout << "lengte zin : " << strlen(zin) << endl;

	// initialiseren van de array

	for(i=0; i<10; i++)
		letters[i]=0;

	bereken(zin, letters);

	for (i=0; i<10; i++)
	{
		cout << "Aantal woorden met " << i+1 << " letters: " << letters[i] << endl;
	}
}

void bereken(char *zinp, int *letters)
{
 int j, letters2;

 letters2=0;
 j=0;
 do
 {
    if ((zinp[j] != ' ') && (zinp[j] != '.'))
       letters2+=1;
	else
	{
	   letters[letters2-1]+=1;
	   letters2=0;
	}
	j++;
 } while (zinp[j] != '.');

 // laatste waarde ook nog in tabel zetten

 letters[letters2-1]+=1;
}
