本文分享了一系列C语言基础IO练习题，包括简单的输入输出操作、格式化打印、基本算术运算等，适合初学者练习掌握C语言的基本语法。

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。。。。
