Counting number of words in a string

This program is used to find the number of words in a string. Now, to do this is actually very simple.
Simply count the number of spaces between words. To do this, simply traverse the string using a loop and
increment a counter variable whenever a space character occurs. Simple :) .!! Do not forget to initialize the
counter variable !!!
Here is the source code : 

// Program to count the number of words in a string
#include <iostream>

int main()
{
     char string[50];
     int counter = 1;
     // prompts the user to enter a string
     std::cout<<" Enter the string ( max 50chars ) : ";
     std::cin.getline(string,sizeof(string));

     for (int i=0; string[i]!= '\0'; i++ )
     {
          if ( string[i] == ' ' )
               counter++;
     }
     std::cout<<"\n Number of Words are : "<<counter;
     return 0;

} // end of main
