check the null terminating character in char

Question

I was just trying to see how to check for the null terminating character in the char   array but I failed  I can find the length using the for loop procedure where you keep on checking each element  but I wanted to just use the while loop and find the null terminating string  I never seem to exit the while loop  Any reason why this is so   char  forward    What is up   int forward length   0  while    forward       0         forward length        printf  Character  d   forward length

You have used   0  instead of   0   This is incorrect  the   0  is a null character  while   0  is a multicharacter literal   Moreover  in C it is OK to skip a zero in your condition   while    forward                   is a valid way to check character  integer  pointer  etc  for being zero

The null character is   0   not   0    while    forward         0

To make this complete  while others now solved your problem    I would like to give you a piece of good advice  don t reinvent the wheel   size t forward length   strlen forward

Your   0  should be   0     you got the slash reversed leaning the wrong way  Your while should look like   while    forward       0      though the      0  part of your expression is optional here since the loop will continue as long as it evaluates to non-zero  null is considered zero and will terminate the loop    All  special  characters  i e   escape sequences for non-printable characters  use a backward slash  such as tab   t   or newline   n   and the same for null   0  so it s easy to remember
