The size of variable length array in c programming must be of integer type and it cannot have an initializer.

The Array.FindIndex (array, pattern) function gets the index of the element that matches the pattern pattern inside the array array in C# if the element is present in the array.

This is the same of write $var = array (array ('index' => 'some value')) character_array[j] = counter; But it is better to use scanf( "%s", character_array ); and read the whole string at once. Note that you character_array array is better to be longer!
