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(). Honestly I have always just taken their functionality for granted as being the easiest way of getting the length of a string. Is it really so much better to do pointer arithmetic? What am I gaining besides more... (3 Replies)
My OS (Debian) and gcc use the UTF-8 locale. This code says that the char size is 1 byte but the size of 'a' is really 4 bytes.
int main(void)
{
setlocale(LC_ALL, "en_US.UTF-8");
printf("Char size: %i\nSize of char 'a': %i\nSize of Euro sign '€': %i\nLength of Euro sign: %i\n",... (8 Replies)
Hello,
This function was copied into my code, which was compiled without error/warning, but when executed there is always Segmentation fault at the end after the output (which seems correct!):
void get_hashes(unsigned int hash, unsigned char *in)
{
unsigned char *str = in;
