作業(yè)一：輸出

include<stdio.h>
int main ()
{
  int a = 0;
  int b = 0;
  int c = 0;
  int d = 0;
  int e = 0;
  printf（"請(qǐng)輸入五個(gè)數(shù)："）；
  scanf（"%d %d %d %d %d",&a,&b,&c,&d,&e）;
  printf("輸出的數(shù)為:%d %d %d %d %d",a,b,c,d,e);
  return 0;
}

作業(yè)二：輸出小數(shù)

include<stdio.h>
int main()
{
  double a = 0;
  double b = 0;
  double c = 0;
  printf("請(qǐng)輸入三個(gè)數(shù):");
  return 0;
}

作業(yè)三：求正方形的面積

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

作業(yè)四：求正方形的面積(2)

include<stdio.h>
int main()
{
  double lenght=0;
  double square=0;
  printf("請(qǐng)輸入正方形的邊長(zhǎng):");
  scanf("%1f",&lenght);
  square=length*length;
  printf("正方形的面積為：%f\n",square);
  return 0;
}

作業(yè)五：求三個(gè)數(shù)的平均數(shù)

include<stdio.h>
int main()
{
  double x=0;
  double y=0;
  double z=0;
  double mean=0;
  printf("請(qǐng)輸入三個(gè)數(shù):");
  scanf("%1f %1f %1f",&x,&y,&z);
  mean=(x+y+z)/3;
  printf("三個(gè)數(shù)的平均數(shù)為：%f\n",mean);
  return ;
}
