篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了* * * * * * * * * * * very good * * * * * * * * * * * 这个东西用c语言得输入啥才能让它输出？相关的知识，希望对你有一定的参考价值。
* * * * * * * * * * * *
* very good *
* * * * * * * * * * * *
要输出这行字符串，C中可以采用两种方法。
1 用printf直接输出。
printf为格式化输出语句，可以直接输出字符串。
调用
printf("* * * * * * * * * * * very good * * * * * * * * * * * ");
即可直接输出该字符串。
2 用puts函数输出。
puts可以直接输出字符串，不过该函数会自动在输出字符串后多输出一个换行。
所以如果要输出字符串后换行，可以直接调用puts，更为高效。
调用方式：
puts("* * * * * * * * * * * very good * * * * * * * * * * * "); 参考技术A 没弄明白你说的是什么意思？
#include<stdio.h>
main()
printf("**********");
printf("verygood");
printf("**********\n");
参考技术B 明显楼上两楼都是错的。
#include(stdio.h)
main
printf("* * * * * * * * * * * *");
printf("\n* very good *\n");
printf("* * * * * * * * * * * *");
本回答被提问者采纳 参考技术C printf("* * * * * * * * * * * very good * * * * * * * * * * * \n");

(2)VC++实现Windows中双显示器（主屏、扩展屏）
Windows中鼠标右键桌面->“屏幕分辨率”时出现的“更改显示器的外观”对话框下实现了双屏操作的诸多功能，如：主屏的设置、主屏和扩展屏的分辨率、方向、屏幕合并等。实际项目中需要通过VC++代码实现这些功能，用了将近一周的事件，在网上经过几番搜索、整合及改写，终于开发出了所需功能。以下将cpp源码贴出，以弥补此方面网上资料的匮乏。完整工程见上传资源Windows下双屏各种设置的VC++实现(完整源码工程)（VS2010下开发）。
