Question

C语言，结构体题目，怎么做，求大神修改一下

#include<stdio.h>#include<stdlib.h>struct Student{int num;char name[20];char sex;int age;float chinese;float math;float english;};int main(){struct Student stu[4]= { {1,"zhangshan","M",20,86.3,88.5,78.5},{2,"lisi","F",18,78.5,76.3,68.5},{3,"wangwu","M",19,90.2,85.6,84.6},{4,"zhaoliu","F",21,76.5,90.5,85.5} };int n=4;int i;int j;struct Student temp;for(i=n-1;i>0;i--){for(j=0;j<i;j++){if(stu[j].chinese<stu[j+1].chinese){temp=stu[j];stu[j]=stu[j+1];stu[j+1]=temp;}}}for(i=0;i<n;i++)printf("%2d%10s%2f%4d%6.2f%6.2f%6.2f\n",stu[i].num,stu[i].name,stu[i].sex,stu[i].age,stu[i].chinese,stu[i].math,stu[i].english);printf("\n");return 0;}

Answer 1

已经修改完成：

#include<stdio.h>

#include<stdlib.h>

struct Student

{ int num;

  char name[20];

  char sex;

  int age;

  float chinese;

  float math;

  float english;

};

int main()

{ struct Student stu[4]=

  { {1,"zhangshan",'M',20,86.3,88.5,78.5},

    {2,"lisi",'F',18,78.5,76.3,68.5},

    {3,"wangwu",'M',19,90.2,85.6,84.6},

    {4,"zhaoliu",'F',21,76.5,90.5,85.5}

  };

  int n=4;

  int i;

  int j;

  struct Student temp;

  for(i=n-1; i>0; i--)

  { for(j=0; j<i; j++)

    { if(stu[j].chinese<stu[j+1].chinese)

      { temp=stu[j];

        stu[j]=stu[j+1];

        stu[j+1]=temp;

      }

    }

  }

  for(i=0; i<n; i++)

    printf("%2d%10s%2c%4d%6.2f%6.2f%6.2f\n",

stu[i].num,stu[i].name,stu[i].sex,stu[i].age,stu[i].chinese,stu[i].math,stu[i].english);

  printf("\n");

  return 0;

}

这些题目的结构也是非常符。修改起来也是非常困难的。一定要认真仔细的修改。
