C语言：编写代码，演示多个字符从两端移动，向中间汇聚

int main()
{
char arr1[] = “welcome to sylu!!!”;
char arr2[] = “******************”;
int left = 0;
int right = strlen(arr1)-1;

while (left <= right)
{
	arr2[left] = arr1[left];
	arr2[right] = arr1[right];
	left++;
	right--;
	printf("%sn", arr2);
	Sleep(1000);
	system("cls");//执行系统命令的一个函数-cls-清空屏幕
}
return 0;

}
