今天把我之前写的大作业分享一下吧，并教你们如何实现，希望你们看了前面的教程也能自己写一个。
1.要先下载一个 graphics.h 的头文件来绘图。
2.初始化窗口：initgraph(x, y);这是先创建一个窗口的函数，以左上角为(0,0)，向右为x轴，向下为y轴，其中x表示长x个单位，y表示宽y个单位。
3.关闭图像窗口：closegraph();结束时用来关闭用的。
4.按任意键继续：getch();这个就和getchar();差不多，为了防止以运行完就关了，这样能停顿一下，他的头文件是：conio.h 。
5.画线：line(x1, y1, x2, y2);在你创建的那么窗口里以(x1,y1)和(x2,y2)为两个端点画线。
6.画矩形：rectangle(x1,y1,x2,y2);以(x1,y1)和(x2,y2)为对角画一个矩形。
7.画圆：circle(x,y,r);以(x,y)为圆点，r为半径画圆。
8.颜色：setcolor(x);用来设置颜色的，其中x是你要设置的颜色，可以填这16种：黑 BLACK、蓝 BLUE、绿 GREEN、青 CYAN、红 RED、紫 MAGENTA、棕 BROWN、浅灰 LIGHTGRAY、深灰 DARKGRAY、亮蓝 LIGHTBLUE、亮绿 LIGHTGREEN、亮青 LIGHTCYAN、亮红 LIGHTRED、亮紫 LIGHTMAGENTA、黄 YELLOW、白 WHITE；当然，你也可以根据光的三原色来调自己喜欢的颜色，方法是：setcolor(RGB(x,y,z));其中RGB分别代表红绿蓝，对应的x,y,z是你选的该颜色的多少，范围是[0,255]。
根据上面的这些就能画出很多图形了.比如：
# include <graphics.h> # include <conio.h> void main() { initgraph(640,480); setcolor(BROWN); line(200,200,300,130); line(400,200,300,130); rectangle(200,200,400,380); setcolor(RGB(100,150,200)); circle(255,260,20); circle(345,260,20); rectangle(280,300,310,360); getch(); closegraph(); }
还有这个，画一个圆，圆心是(320,240),半径r=200，根据角度的公式画一个圆：
# include <graphics.h> # include <conio.h> # include <math.h> # define PI 3.1415926 void main() { initgraph(640, 480); int x,y,r=200,c; double a; for(a=0; a<PI*2; a+=0.0001) { x=(int)(r*cos(a)+320+0.5); y=(int)(r*sin(a)+240+0.5); c=(int)(a*255/(2*PI)); setcolor(RGB(c,200-c/2,100+c/2)); line(320,240,x,y); } getch(); closegraph(); }
9.停顿：Sleep(x);停顿x/1000秒。
有了Sleep();函数，就能让线动起来了，原理就是：先画一条线，然后再画一条黑色的线覆盖原来的那条，然后再画一条线，这样不断的画线能行了。
# include <graphics.h> # include <conio.h> void main() { int i,y; initgraph(640,480); for(y=0;y<480-2;y++) { setcolor(RGB(y,125,y/2%256)); line(0,y,639,y); line(0,y+2,639,y+2); Sleep(10); setcolor(BLACK); line(0,y,639,y); } getch(); closegraph(); }
10.随机数发生器：srand();使用方法：srand(time(NULL));使用时要有头文件time.h。
11.随机函数:rand();随机生成一个数，头文件是：stdlib.h，比如：
# include <stdio.h> # include <time.h> # include <graphics.h> void main() { int t=10; while(t--) { srand(time(NULL)); printf("%d\n",rand()); Sleep(1000); } }
12.判断键盘是否有输入：kbhit();如果有的话返回1，否则返回0.
13.方向键：方健健的ASCII值我们不知道，普通的getchar();也不能输入，但是getch();通过运行程序可以发现方向比较特殊，分别是：上 224+72、下 224+80、左 224+75、右 224+77，就是说他们是由两个字符组成的，所以判断上下左右时就先判断if(kbhit()),然后判断if(getch()==224),如果是的话在判断if(getch()==72),是的话就是上，下左右同理。
# include <stdio.h> # include <graphics.h> # include <conio.h> void main() { int key; while(1) { if(kbhit()) { key=getch(); if(key==224) key=getch(); printf("%d",key); } else printf("*"); Sleep(500); } }
14.输出：outtextxy(x,y,s);在坐标为(x,y)的地方输出字符串s。
15.数字转字符串：sprintf(s,”%d”,a);将数字a,转化为字符串s，头文件是stdio.h。
16.设置字体：setfont(x,y,”字体”);其中x表示你你要输出的字的大小，y会改变形状一般都是设为0，”字体”为你想要输出的字体，比如：setfont(40,0,”楷体”);
# include <graphics.h> # include <conio.h> # include <stdio.h> void main() { char s[10]; initgraph(640,480); setfont(42,0,"隶体"); outtextxy(200,200,"俄罗斯方块"); sprintf(s,"%d",2015); outtextxy(250,250,s); getch(); closegraph(); }
上面这些都学会了的话，差不多就能够自己完成编写一个俄罗斯方块了，下面分享一下我写的代码。
# include <stdio.h> # include <time.h> # include <conio.h> # include <graphics.h> int a,visit[30][15],Color[30][15],minX=30,minY=30,maxX=310,maxY=610,speed=500,score=0,rank=0; int color[]={GREEN,CYAN,MAGENTA,BROWN,LIGHTGRAY,LIGHTBLUE,LIGHTGREEN,LIGHTRED,YELLOW};

我设置的一行能放15个小格子，一共能放30行，二维数组visit[30][15],来判断某个位置是否有方块，比如visit[29][5]=1表示第30行第6个方块的位置有方块了，0表示没方块,Color[30][15]用来记录某个位置的方块的颜色。minX=30,minY=30表示左上角的方块也就是第1行第1列的方块对应在界面的坐标，maxX,maxY同理。speed表示方块的下落速度，一开始初始化为500，没0.5s往下落一行，score记录分数，每消一行加10分，rank表示等级，每50分等级+1，且速度减100，当速度减到100时，就不变了，只有当分数超过300速度才会减为75，且以后都不会再减少了。
我一个设计了9种方块，每种方块都有4种形态，每顺时针旋转90°就有一种形态，所以一共是36个方块。每个方块都用5*5的二维数组来表示，36种就是36个二维数组，所以用block[36][5][5]来表示，block[k][5][5],（k<36&&k%4==0）表示每种方块的初始形态，k+1，+2，+3,分别表示第k种方块选择90°、180°、270°之后的形态。比如block[1][5][5]保存的是第1种方块旋转90°的方块，其中block[1][i][j]=1表示这个方块第i+1行，j+1列有一个小方块，=0代表没有，所以我的block[36][5][5]，有36行，一行25个数列，表示一种方块。一维数组color[]依次表示9种方块的颜色。
