编写代码，演示多个字符从两端移动，向中间汇聚

运行代码：

#define _CRT_SECURE_NO_WARNINGS 1
#include
#include
#include
int main(void)
{
	//4.编写代码，演示多个字符从两端移动，向中间汇聚
	char arr1[] = "welcome to bit";
	char arr2[] = "##############";
	int left = 0;
	int right = sizeof(arr1)/sizeof(arr1[0]) - 2;
	while (left <= right)
	{
		arr2[left] = arr1[left];
		arr2[right] = arr1[right];
		printf("%s\n", arr2);
		Sleep(100);//S要大写
		left++;
		right--;
	}
	return 0;
}

解释：sizeof(arr1)/sizeof(arr1[0]) 是表示数组含元素的个数！
