1.複習瘋狂程設題目

/// 讀入整數反序列印


#include <stdio.h>
int a[20];
int main()
{
int i=0;
while(i<10)
{
scanf("%d",&a[i]);
if(a[i]==0)break;
i++;
}
for (int j=i-1;j>=0;j--)
{
printf("%d ",a[j]);
}
printf("\n");
return 0;
}

///大小寫轉換



#include <stdio.h>
char line[20];
int main()
{
scanf("%s", line);

for (int i=0; line[i]!=0;i++)
{
char c=line[i];
if(c>='A' && c<='Z')
{
line[i]=c-'A'+'a';
}
else if(c>='a'&&c<='z')
line[i]=c-'a'+'A';

}
printf("%s\n", line);

}



//int []a=new int[10];//Java's Array
//int []a={3,0,1,8,7,2,5,4,6,9};//https://www.youtube.com/watch?v=lyZQPjUT5B4
//int []a={6,3,5,9,1,0,4,2,7,8};
//int []a={1,2,3,5,0,4,6,7,8,9};
//int []a={0,9,1,2,3,5,4,6,7,8};//對於快要排好的東西, 特別快!!!
int []a={9,8,7,6,5,4,3,2,1,0};//最糟的狀況:全倒 => QQ
void setup(){
  size(500,800);
  //for(int i=0;i<10;i++){//random choose number
  //  a[i]=int(random(10));//亂數決定數字
  //}
  textSize(36);
  textAlign(LEFT,TOP);
  showArray(y);
}
int y=0;
void showArray(int y){
  for(int i=0;i<10;i++){
    fill(255);  rect(i*50, y, 50,50);
    fill(0);         text(a[i], i*50, y);
  } 
}
void draw(){

}
void mousePressed(){
  for(int i=0; i<10-1;i++){
    if(a[i] > a[i+1]){
      int temp=a[i];
      a[i]=a[i+1];
      a[i+1]=temp;
      fill(255,0,0,128); rect(i*50, y, 100,50);
    }
  }
  y+=50;
  showArray(y);
}

會張嘴
void setup()
{
  size(400,400);
}
int x=100,y=100,angle=45,diff=1;
void draw()
{
  background(0);
  arc(x,y,80,80,radians(angle),radians(360-angle),PIE);
  angle+=diff;
  if(angle>60)diff=-1;
  if(angle<0)diff=+1;
}

還會跑
void setup()
{
  size(400,400);
}
int x=100,y=100,dx=1,dy=0,angle=45,diff=1;
void draw()
{
  background(0);
  arc(x,y,80,80,radians(angle),radians(360-angle),PIE);
  angle+=diff;
  if(angle>60)diff=-1;
  if(angle<0)diff=+1;
  x+=dx; y+=dy;
}
void keyPressed()
{
  if(keyCode==RIGHT){dx=+1;dy=0;}
  if(keyCode==LEFT){dx=-1;dy=0;}
  if(keyCode==UP){dx=0;dy=-1;}
  if(keyCode==DOWN){dx=0;dy=+1;}

}


可以控制方向了
void setup()
{
  size(400,400);
}
int x=100,y=100,dx=1,dy=0,angle=45,diff=1,dir=0;
void draw()
{
  background(0);
  arc(x,y,80,80,radians(dir+angle),radians(dir+360-angle),PIE);
  angle+=diff;
  if(angle>60)diff=-1;
  if(angle<0)diff=+1;
  x+=dx; y+=dy;
}
void keyPressed()
{
  if(keyCode==RIGHT){dx=+1;dy=0;}
  if(keyCode==LEFT){dx=-1;dy=0;}
  if(keyCode==UP){dx=0;dy=-1;}
  if(keyCode==DOWN){dx=0;dy=+1;}

}

可以玩囉
int[][]bean=
{
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
  {1,1,1,1,1, 1,1,1,1,1},
};
void setup()
{
  size(400,400);
}
int x=100,y=100,dx=1,dy=0,angle=45,diff=1,dir=0;
void draw()
{
  background(0);
  fill(255);
  for(int y=0;y<10;y++)
  {
    for(int x=0;x<10;x++)
    {
      if(bean[y][x]==0)continue;
      ellipse(20+x*40,20+y*40,10,10);
      if(dist(x,y,20+x*40,20+y*40)<20)bean[y][x]=0;
    }
  }
  fill(#FFCF0D);arc(x,y,40,40,radians(dir+angle),radians(dir+360-angle),PIE);
  angle+=diff;
  if(angle>60)diff=-1;
  if(angle<0)diff=+1;
  x+=dx; y+=dy;
}
void keyPressed()
{
  if(keyCode==RIGHT){dx=+1;dy=0;}
  if(keyCode==LEFT){dx=-1;dy=0;}
  if(keyCode==UP){dx=0;dy=-1;}
  if(keyCode==DOWN){dx=0;dy=+1;}

}
