    With size() method. Or if you are using char arrays, then strlen() (#include <cstring>). Or if you want to do it yourself , just go through the characters with while loop.

    Code:
    int Length(char* a) {
    
      int count = 0;
      char *aux = a;
    
      while (*aux != '\0') {
        count++;
        aux++;
        }
    
      return count;
      }

    Or...

    int size = sizeof( Array ) / sizeof( char );

    where array is the variable name and char is the type of
    data stored in your array.
