c语言编程 高分 c语言编程，输出最高分和最低分，为什么出错了···

 
 
 
可以这样写：

#include <stdio.h>

    Gender   gender;
    unsigned scores[ NumberOfSubjects ];
}

}

    int i = 1;
    for ( ; i < NumberOfStudents; i++ )
        if ( students[ i ].scores[ sji ] > top.scores[ sji ] )
            top = students[ i ];
    return top;
}

bool failingAtLeastOneSubject( Student stu ) {
    int i = 0;
    for ( ; i < NumberOfSubjects; i++ )
        if ( stu.scores[ i ] < PassingScore )
            return true;
    return false;
}

void main( ) {
    int i;

    puts( "Format of displayed student data:\n" );
    printHeader( );

    puts( "\n>>> Top scorers of Literature, History and Programming (in that order):\n" );

/*用结构体就OK了~很简单,程序如下~(Dev C++)*/

#include<iostream>
#include<string>
using namespace std;

struct student
{
int id;
string name;
int sex;
//1是男,2是女,3是人妖,4是无性别的
int score[2];
}stu[9]=....//自己定义

int main()
{
int max=-1;
int scores;
int who;
int bjg[9];
int bjgtotal=-1;
int i;
for (i=0;i<=9;i++)
{
scores=stu[i].score[0]+stu[i].score[1]+stu[i].score[2]
if (scores>max)
{
max=scores;
who=i;
}
if (stu[i].score[0]<60 || stu[i].score[1]<60 || stu[i].score[2]<60){
//60分算及格吧
bjgtotal=bjgtotal+1;
bjg[bjgtotal]=i;
}
}
show(who,"最高分");
for (i=0;i<=bjgtotal;i++)
{
show(i,"不及格");
}
system("pause");
}

void show(int whois,string words)
{
int i;
int pj;
cout<<words<<"的是"<<stu[whois].name<<",他/她/它的学号是"<<stu[whois].id<<",性别是"<<stu[whois].sex<<",三门成绩分别是";
for (i=0;i<=2;i++)
{
cout<<stu[whois].score[i]<<" ";
pj=pj+stu[whois].score[i];
}
pj=pj/3;
cout<<"平均分是"<<pj<<"。"<<endl;
}

/*OK了，如果你还可以枚举性别，这里就不祥写了，偶还要赶时间。。。*/

给我加分吧。程序已经测试过了！
llf18018为什么拷贝我的答案？太过分了吧？

#include <stdio.h>

#define SIZE 10

ok有了标准答案告一下

}

我觉得用结构体比较简单
一个学生是一个结构体变量，他的学号，姓名，性别等信息是结构体的成员
这样启不是简单
用不着数组
要用的话，也有结构体数组

C语言编程 题目：输入30个学生成绩，求最高分，最低分和平均分（用数组存放数据）~

#include
intmain（）
{
intmax，min，score；
doubleavg=0；
scanf（"%d"，&score）；
max=min=score；
avg+=score；
for（inti=0；i<29；i++）
{
scanf（"%d"，&score）；
if（score>max）max=score；
if（score<min）min=score；
avg+=score；
}
avg=avg/30；
printf（"最高分max=%d，最低分min=%d，平均分avg=%lf
"，max，min，avg）；
return0；
}

文件输入/输出
在C语言中，输入和输出是经由标准库中的一组函数来实现的。在ANSI C中，这些函数被定义在头文件；中。
标准输入/输出
有三个标准输入/输出是标准I/O库预先定义的：
stdin标准输入
stdout标准输出
stderr输入输出错误
以上内容参考：百度百科-c语言
