title: Is there an alternative to declaring a variable inside a for loop?
body: <p>I am trying to count the number of odd values in the elements of the array. Is there a way to perform the below operation without declaring a variable inside the for loop? I am aware that the variable declared inside the loop cannot be accessed outside the loop and I want to know if there is a way that the following loop is performed and the value of oddValueCountKS could be accessed outside of the loop.</p>
  <pre class="lang-cpp prettyprint-override"><code>int arr[3] = {1004, -237890, 30022};
       
  for (int i = 0; i &lt; 3; i++) {
    int oddValueCountKS = 0;
           
    while (arr[i] != 0) {
      if (arr[i] % 2) {
        oddValueCountKS++;
      }
      arr[i] /= 10;
    }
  }
