C语言中const char *字符进行切割实现

将127.0.0.1以"""."来进行切割，实现如下：

    const char * ip = "127.0.0.1";

	char *test = new char[100];

	strcpy(test, ip);

	const char *split = ".";

	char *final;

	final = strtok(test, split);

	while (final)
	{
		printf("%s\n", final);

		final = strtok(NULL, split);
	}
	return 0;

最终实现效果：

想要将字符转成整形，如下：

#include <stdio.h>
#include <iostream>

//借助strtok实现split
#include <string.h>

int main()
{
	const char * ip = "127.0.0.1";

	char *test = new char[100];

	strcpy(test, ip);

	const char *split = ".";

	char *final;

	final = strtok(test, split);

	while (final)
	{
		printf("%s\n", final);

		int c = atoi(final);

		printf("data = %d\n", c);

		final = strtok(NULL, split);
	}
	return 0;
}
