How can I find the length of a character pointer in 'C'?

TIA

If you mean the number of chars in the array the pointer points to,
then the general answer is: you can't. If this pointer points to an
array, where the end of the array is signalled by a 0-char, then you can
use strlen.

With sizeof(char*).

Thanks folks!
The function I was looking for is strlen().

To the OP:

You could have avoided such replies by leaving out the word 'C' in your
question or by replacing it with 'C++'. Since you specified a language
that this group is not about you get smart-ass answers like the above.
However, without having specified the language as something other than
C++ your question would have been totally on-topic.

Use strlen()

be careful with strlen, because it counts until a '\0'... the array
could be more longer ;-)

sizeof(char*);

length returned is in bytes.

If you mean the length (size would be a more appropriate term) of a
character pointer then just use 'sizeof(char*)'. For the length of a
string pointed to by the character pointer use 'strlen'.
