C++基础-反转字符串

反转字符串

void reverseStr(char *m_str)
{

	char *p1 = m_str;
	char *p2 = m_str + strlen(m_str)-1;
	while (p1<p2)
	{
		char c = *p2;
		*p2 = *p1;
		*p1 = c;
		p1++;
		p2--;

	}

}

void main()
{
	char str[] = "abcdefghijk";
	printf("反转之前：%s\n", str);
	reverseStr(str);
	printf("反转之后：%s\n", str);
	reverseStr(str);
	printf("反转回来：%s\n", str);
	
	system("pause");
}

结果:
