Taking the 'const' doesn't make any difference. I could use 'sizeof', but it gives one greater than the length (is it counting a null terminator?). I'm not sure why it says it's not constant as I'm doing a strlen on a pair of constant strings, so their length can't change.
sizeof() is not the same as strlen(). sizeof() gives you the size of the array. Whereas strlen() counts the number of chars in the array until a '\0' is found. Your problem is totally related to the compiler (gcc in your case).
Those declarations are global right? Try declaring them global but without assigning the value of comment_begin_len and comment_end_len.
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)

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)
Hi. I define my variables as:
month=jul
DD=17
YEAR=2012
transmission_file_name_only=test_$month$DD$YEAR_partial.dat
However when I run my script the variable 'transmission_file_name_only' resolves to:
File "/downloads/test_jul17.dat" not found.
How can I append this '_partial'... (3 Replies)
Hi All !
I am just trying to print bash variable in awk statement as string
here is my script
n=1
for file in `ls *.tk |sort -t"-" -k2n,2`; do
ak=`(awk 'FNR=='$n'{print $0}' res.dat)`
awk '{print "'$ak'",$0}' OFS="\t" $file
n=$((n+1))
unset ak
doneI am getting following error

I wonder string constant exists permanently or temporary.
For example,
printf("hello, world");
the function printf access to it is through a pointer. Does it mean storage is allocated for the string constant to exist permanently in memory? :confused: (4 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!):

unsigned char *str = in;
