strlen()

The strlen() string function returns the length of the string without including the terminating character, '\n'.

strlen(string)

It takes in the string and returns an unsigned short.

#include <stdio.h>
#include <string.h>

int main() {
  char spell[20] = "Abracadabra";
  printf("Length: %i", strlen(spell));
  return 0;
}

The output would be:

Length: 11

Notice how it didn’t count the terminating character.
