移除字符串中连续2个0 (连续3个或3个以上不需要移除)

这个版本比之前发布的版本更为简洁 故重新发一遍

#include <cstdio>

void remove2zeros(char *str)
{
	int count = 0;
	char* base = str, *cur = str;

	while (*cur != '\0')
	{
		if (*cur == '0')
			count++;
		else
		{
			if (count == 2)
				base -= 2;

			count = 0;
		}

		*base = *cur;
		cur++;
		base++;
	}

	*base = '\0';
	return;
}

int main()
{
	char src[] = "a3409jd00dk000d";

	remove2zeros(src);
	return 0;
}
