Problem s fci v C – C / C++ – Fórum – Programujte.com

Ahoj. Mam problem - tvorim linuxovou aplikaci v jazyce C a potrebuji fci, ktera by cetla text(mmaped file) az k urcite hranici a pocitala by radky. Napsal jsem to takhle:

unsigned int

row_count(const char *string, const size_t len)

{

	unsigned int count = 0;

	char *tmp;	

	tmp = string;

	while (((tmp = strstr(tmp, "\n")) != NULL) && (tmp-string < len))

		++count;

	return (count);

}

a co takhle?

row_count(char *string, const size_t len)

{

      unsigned int count = 0;

      char *tmp;

      tmp = string;

      while (((tmp = strstr(tmp, "\n")) != NULL) && (tmp-string < len))

            ++count;

      return (count);

}

co alokace paměti?

To gody : asi to tvoj problém nevyrieši, ale za prvým riadkom ti chýba stredník :)

unsigned int;

To gaben : nechýba

skús toto:

size_t row_count(const char * str, const size_t len)

{

	size_t count = 0;

	for (size_t i = 0; i < len; ++i)

	{

		if (str[i] == '\n')

			++count;

	}

	return count;

}
