Counting all characters in a string

How do i count all the characters in a string?

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.
