IO-00:

#include<stdio.h>int main(){printf("Hello World!");}

IO-01：

#include<stdio.h>

int main(){  printf("------------------------------------\n");  printf("Province      Area(km2)   Pop.(10K)\n");  printf("------------------------------------\n");  printf("Anhui         139600.00   6461.00\n");  printf("Beijing        16410.54   1180.70\n");  printf("Chongqing      82400.00   3144.23\n");  printf("Shanghai        6340.50   1360.26\n");  printf("Zhejiang      101800.00   4894.00\n");  printf("------------------------------------");}

IO-02:

<pre name="code" class="cpp">#include<stdio.h>int main(){  int A,B;  scanf("%d %d",&A,&B);  printf("%d + %d = %d\n",A,B,A+B);  printf("%d - %d = %d\n",A,B,A-B);  printf("%d * %d = %d\n",A,B,A*B);  printf("%d / %d = %d\n",A,B,A/B);}

IO-03:

#include<stdio.h>int main(){  int a,b,c,d;  float sum,aver;  scanf("%d %d %d %d",&a,&b,&c,&d);  sum=a+b+c+d;aver=sum/4;  printf("Sum = %.0f; Average = %.1f",sum,aver);  return 0;}

IO-04:

#include<stdio.h>int main(){  int b;  float a,c;  char k;  scanf("%f %d %c %f",&a,&b,&k,&c);  printf("%c %d %.2f %.2f",k,b,a,c);}

IO-05:

#include<stdio.h>int main(){  printf("Programming in C is fun!");}

IO-06:

#include<stdio.h>int main(){  printf("What is a computer?");}

IO-07:

#include<stdio.h>int main(){  printf("Welcome to You!");}

IO-08:

#include<stdio.h>int main(){  printf("* * * *\n");  printf(" * * *\n");  printf("  * *\n");  printf("   *\n");}

IO-09:

#include<stdio.h>int main(){  int a,b;  scanf("%d",&a);  b=5*(a-32)/9;  printf("Celsius = %d",b);}

这几个题就是我最开始接触的ACM的题，都是最水的题，就把PAT上几道基础题作为博客的开端。

当时就是这几道题还有两三个PE了呢

现在看起来格式好差的说。。。。
