作业一：输出

include<stdio.h>
int main ()
{
  int a = 0;
  int b = 0;
  int c = 0;
  int d = 0;
  int e = 0;
  printf（"请输入五个数："）；
  scanf（"%d %d %d %d %d",&a,&b,&c,&d,&e）;
  printf("输出的数为:%d %d %d %d %d",a,b,c,d,e);
  return 0;
}

作业二：输出小数

include<stdio.h>
int main()
{
  double a = 0;
  double b = 0;
  double c = 0;
  printf("请输入三个数:");
  return 0;
}

作业三：求正方形的面积

include<stdio.h>
int main()
{
  int length = 6;
  int square = 0;
  square=length*length;
  printf("正方形的面积为：%d\n",square);
  return 0;
}

作业四：求正方形的面积(2)

include<stdio.h>
int main()
{
  double lenght=0;
  double square=0;
  printf("请输入正方形的边长:");
  scanf("%1f",&lenght);
  square=length*length;
  printf("正方形的面积为：%f\n",square);
  return 0;
}

作业五：求三个数的平均数

include<stdio.h>
int main()
{
  double x=0;
  double y=0;
  double z=0;
  double mean=0;
  printf("请输入三个数:");
  scanf("%1f %1f %1f",&x,&y,&z);
  mean=(x+y+z)/3;
  printf("三个数的平均数为：%f\n",mean);
  return ;
}
