字符串逆序

代码实现

#include
void swap(char* ch1, char* ch2)
{
	char tmp = *ch1;
	*ch1 = *ch2;
	*ch2 = tmp;
}
void reverse_string(char* string)
{
	int left = 0;
	int right = strlen(string) - 1;
	while (left < right)
	{
		swap(string + left, string + right);
		left++;
		right--;
	}
}
void main()
{
	char arr[] = "abcdefgh";
	reverse_string(arr);
	printf("%sn", arr);
}
