The default value for a single char in C is usually promoted to an int. sizeof(int) = 4
but that does not mean that a single 'a' character actually is that large - 4 bytes.
A char in UTF-8 is 1 byte.
Your compiler stores a single char variable in the space it uses for an int. That is the bottom line for all the confusion.
BTW: CHAR_BIT by standard is currently defined to be fixed at 8, regardless of how the compiler decides to promote it. And regardless of what the locale may be. Which is why you should not change it to 32.
See C99 standards 5.2.4.2.1 Sizes of integer types <limits.h>

hello,
i have a problem with strlen. I have written this:
for(y=13,z=0; cInBuf!=' ';y++)
{
cBuf=cInBuf;
z++;
}
len = strlen(cBuf);
out=len/2;
fprintf(outfile,"F%i",out);
If strlen is e.g. 22, it write F22. I want to write F2F2.
How can i do this?... (5 Replies)

I have been getting some flack recently for my use of strlen() and strnlen().
