I have read that use of
strlen is more expensive than such testing like this:
We have a string
x 100 characters long.
I think that
for (int i = 0; i < strlen(x); i++)
is more expensive than this code:
for (int i = 0; x[i] != '\0'; i++)
Is it true? Maybe the second code will not work in some situation so is it better to use the first?
Will it be better with the below?
for (char *tempptr = x; *tempptr != '\0'; tempptr++)
