Turns all the char words in the opposite way using getline, array in c++

Question

char reversevirkne(char virkne[]) {
    int apgriests, x = 0;

    for (int i = 0; virkne[i] != ''; i++) {
        x++;
    }
    x--;
    for (int j = x; j >= 0; j--) {
        apgriests = (int)virkne[j];
        std::cout << virkne[j];
    }

    std::cout << std::endl;
    return 0;
}

This program turns all of the sentence to the opposite way. I need it to turn only the words so they would stay in there positions. example:

• input: hello world
• output: olleh dlrow

This really not complicated to do :

#include <iostream>
#include <string>

void reversevirkne(const char virkne[]) {
  std::string w;

  for (int i = 0; virkne[i] != ''; ++i) {
    if (virkne[i] > ' ') // test also manages 	
      w = virkne[i] + w;
    else if (!w.empty()) {
      std::cout << w << ' ';
      w.clear();
    }
  }

  std::cout << w << std::endl;
}

int main(int, char **)
{
  reversevirkne("hello world");
  return 0;
}
