指法练习软件TT

发布时间：2023年12月25日

1、说明

? ? ? ? ?这个是90年代后期读书时写的C语言练习软件，模仿当时的打字练习软件。

? ? ? ? ?在技能上使用屏幕直接输出，支持彩色，能够在DOS和Windows98的窗口下运行。

2、主要界面

? ? ? ?支持多用户档案，以键盘操作。

? ? ?进入具体用户档案后，支持各类实时统计。

3、主要代码TT.C

Mr. Prime Minister and all of your distinguished guests this
 evening:
 On behalf of all of your American guests, I wish to thank
 you for the incomparable hospitality for which the Chinese
 people are justly famous throughout the world.I particularly
 want to pay tribute, not only to whose who prepared the magnificent
 diner,but also to whose who have provided the splendid music. Never
 have I heard American music played better in a foreign land.
 Mr. Prime Minister, I wish to thank you for your very gracious
 and eloquent remarks. At this very moment,through the wonder of
 telecommunications,more people are seeing and hearing what we say
 than on any other such occasion in the whole history of the world.
 Yet,what we say her will not be long remembered.What we do here
 can change the world.
 As you said in your toast,the Chinese people are a great people,
 the American people are a great poeple.If our two peoples are
 enemies,the future of this world we share together is dark indeed.
 But if we can find common ground to word together,the chance for
 world peace is immeasurably increased.
 In the spirt of frankness which I hope will characterize our tallks
 this week,let us recognize at the outset these points: We have at times
 in the past been enemies. We have great differences today. What brings
 us together is that we have common interests which transcend those
 differences.As we discuss or differences,neither of us will compromise our
 principles. But while we cannot close the gulf between us ,we can try to
 bridge is so that we may be able to talk across it.
 So,let us in these next five days,start a long march together,not in the
 lockstep,but on different roads leading to the same goal, the goal of
 building a world structure of peace and justice in which all  may stand togeter
 with equal dignity and in which each nation,large or small,has a right to determine
 its own form of government, free of outside interference or domination. The
 world watches. The world listens. The world waits to see what we will do.
 What is the world? In a personal sense,I think of my eldest daughter whose
 birthday is today. As I think of her,I think of all the children in the world,
 in Asia,in Africa,in Europe,in the americas, most of whom were born since the
 date of the foundation of the People's Republic of China.
 What legacy shall we leave out children? Are they distined to die for the hatreds
 which have plagued the old world,or are they destined to live because we had
 the vision to build a new world.
 There is no reason for us to be enemies. Neither of us seeks the territory
 of the other;neither of us seeks domination over the other;neither of us seeks
 to stretch out our hands and rule the world.
 Chairman Mao has written, "so many deeds cry out to be done,and always urgently;
 The world rools on. Time presses. Ten thousand years are too long. Seize the day,
 seize the hour!"
 This is the hour. This is the day for our two peoples to rise to the heights
 of greatness which can build a new and a better world.
 In the spirit, I ask all of you present to join me in raising your glasses to
 Chairman Mao,to Prime Minister Zhou,and to the friendship of the Chinese and
 American people which can lead to friendship and peace for all people in the world.
