设某班有50个学生，现要求： 1，键盘输入该班所有同学数学成绩
2，求全班同学数学课程平均成绩并统计高出平均成绩的学生人数 要求用C语言编写程序 急用谢了 请编程高手帮帮忙

Answer 1

#include<stdio.h>
#define N 50
int main()
{
float score[50],sum=0.0f,ave;
int i,count=0;
printf("Input all scores:\n");
for(i=0;i<N;i++)
{
printf("the %d's score is:",i+1);
scanf("%f",&score[i]);
sum+=score[i];
}
ave=sum/N;
for(i=0;i<N;i++)
if(score[i]>ave)
count++;
printf("The average score is:%.1f\n",ave);
printf("The students whose score is over average score are:%d\n",count);
return 0;
}

晃过

Answer 3

这是例题呀

Answer 4

还是用这个吧,是hahugo88编的;
#include<stdio.h>
#define N 50
int main()
{
float score[50],sum=0.0f,ave;
int i,count=0;
printf("Input all scores:\n");
for(i=0;i<N;i++)
{
printf("the %d's score is:",i+1);
scanf("%f",&score[i]);
sum+=score[i];
}
ave=sum/N;
for(i=0;i<N;i++)
if(score[i]>ave)
count++;
printf("The average score is:%.1f\n",ave);
printf("The students whose score is over average score are:%d\n",count);
return 0;
}

Answer 5

请用粘贴到记事本，把(扩展)名改为"*.c"。

// 环境：TC 3.0
// C语言

#include<stdio.h>
#include<stdlib.h>
#include<string.h> //字符串函数
#include<conio.h> //屏幕操作函数
#include<mem.h> //内存操作函数(VC6.0打开有误)
#include<ctype.h> //字符串函数

typedef struct
{ char no[16],name[30]; //学号、姓名
int score;
}STUDENT;

STUDENT student[50];

void main()
{
int i,m,sum=0;
float average;
for(i=0;i<50;i++)
{
clrscr();
gotoxy(20,6);printf("Enter Student %d Number:",i);
scanf("%s",student[i].no);
gotoxy(20,7);printf("Enter Student Name:");
scanf("%s",student[i].name);
gotoxy(20,8);printf("Input Math score:");
scanf("%d",&m);
student[i].score=m;
sum=sum+student[i].score;
}
average=1.0*sum/3;
sum=0;
clrscr();gotoxy(20,5);
printf("Students Who's score>Average are below:");
for(i=0;i<50;i++)
{
if(1.0*student[i].score>average)
{
sum++;
gotoxy(20,5+sum);
printf("%d: %s %s %s", sum,student[i].no,student[i].name,student[i].score);
}
}
gotoxy(20,7+sum);
printf("Please press any key to return!");
getch();
}

#include <stdio.h>
int main()
{
int score[50], sum=0, s=0, ave;
for(int i=0; i<50; i++)
{
printf("请输入%d号学生的成绩：\n",i+1);
scanf("%d",&score[i]);
getchar();

sum+=score[i];
}
ave=sum/50;
for(int j=0; j<50; j++)
{
if(score[j]>=ave)
s++;
}
printf("~~~~~~~~~~~~~~~~~~~~~~\n");
printf("全班平均成绩为：%d\n高出平均成绩的人数有%d人\n",ave,s);
getchar();
}
