array length check

ERrrm, i'm new here. and i'm a beginner in programming

i was wondering if there was a function to check the array length
example:

char array[50] = "Blah";

is there a way to check how long "blah" is? (in otherwords, how many spaces are actually used in the array[50])

all your responses are greatly appreciated.

Just use the sizeof() keyword.

Code:

---

cout << sizeof(blah);
