Question
Knowing the call to strlen() within the loop conditional below is inefficient, why doesn’t even a good compiler move the call to strlen() out of the conditional such that it is only called once?
// assume i is an int and s is a character string
for (i = 0; i < strlen(s); i++)
if (s[i] >= 65 && s[i] <= 97)
s[i] += 32;
