String array HELP

[ivDwAqkS]

Is there any way to fix this bug? I would like to print the string array but if some of the element is not a or c, it has to change the letter to X. why it doesn't print?

#include <iostream>
#include <string>
using namespace std;
string arr[5]={"a", "b", "c", "d", "e"};

int main(){
  int counter;
  for(counter = 0; counter < 5; counter++){
     if(arr[counter]!= "c" || arr[counter]!= "a")//this doesn't print why?
       cout << "X" << endl;                    //correction: change || for &&
     else
       cout << arr[counter] << endl;
  }
  return 0;
}

You used the logical-or operator instead of the logical-and operator. It can't be both a and c at the same time, so one of the conditions always fails.

so I just have to change it by &&? THANKS L B
