#include<stdio.h>
#include<string.h>
#include<windows.h>
#include<stdlib.h>
int main()
{
	int sl = strlen("welcome bit !!!!!!");//strlen()遇到\0会停止！！！
	char arr1[] = "welcome bit !!!!!!";
	char arr2[] = "##################";
	int left = 0;
	int right = sl - 1;
	
	while (left<right)
	{
		arr2[left] = arr1[left];
		arr2[right] = arr1[right];
		left++;
		right--;
		printf("%s\n", arr2);
		Sleep(500);
		system("cls");
		
	}
	printf("welcome bit !!!!!!");
	return 0;
}

注意：sleep() 单位为ms
