Use strlen() to get the length of a char array buffer

  

#include <iostream>

#include <string.h>

using namespace std;

int main()

{

   char buffer[80];

   do

   {

      cout << "Enter a string up to 80 characters: ";



      cin.getline(buffer,80);



      cout << "Your string is " << strlen(buffer);



      cout << " characters long." << endl;

   }while (strlen(buffer));

   return 0;

}
