㈠ 平均成績計算 c語言程序編寫
# include<stdio.h>
# include<stdlib.h>
# include<string.h>
#define N 10//修改學生人數
struct data
{ int number;
char name[20];
int score[3];
float ave;
int sum;
}stu[10];
void ave(struct data stu[],int n)
{int sum[3]={0,0,0},i,j;
for(i=0;i<3;i++)
for(j=0;j<n;j++)
sum[i]+=stu[j].score[i];
for(i=0;i<3;i++)
printf("第%d門課程的平均成績:%d\n",i+1,sum[i]/n);
}
void main()
{int i,j,m;
char str[20];
int a,c;
float d;
for(i=0;i<N;i++)
{printf("the %d student 學號:",i+1);
gets(str);
stu[i].number=atoi(str);
printf("姓名:");
gets(stu[i].name);
printf("3門課的成績分別為：");
stu[i].sum=0;
stu[i].ave=0;
for(j=0;j<3;j++)
{gets(str);
stu[i].score[j]=atoi(str);
stu[i].sum+=stu[i].score[j];
stu[i].ave+=stu[i].score[j];
}
(float)stu[i].ave/=3;
}
ave(stu,10);
for(i=0;i<N;i++)
printf("\n%2d%6s%3d%10d%9d%9d%8d %4.2f",i+1,stu[i].name,stu[i].number,stu[i].score[0],stu[i].score[1],stu[i].score[2],stu[i].sum,stu[i].ave);
printf("\n");
}
㈡ 用C語言編寫 運動會分數統計系統
200分，可以考慮。
㈢ C語言求平均成績
#include<stdio.h>
intmain()
{
floata[5][50],s,av;
inti,j,stu,sub,count;
while(scanf("%d%d",&stu,&sub))
{
for(i=0;i<stu;i++)
for(j=0;j<sub;j++)
scanf("%f",&a[i][j]);//輸入信息
for(i=0;i<stu;i++)
{
for(j=0,s=0;j<sub;j++)
s+=a[i][j];
av=s/sub;
if(j!=stu-1)
printf("%.2f",s/sub);//這里應該是%f，下同
else
printf("%.2f",s/sub);
}
printf(" ");//這里要換行
for(i=0;i<sub;i++)
{
for(j=0,s=0;j<stu;j++)
s+=a[j][i];
if(j!=sub-1)
printf("%.2f",s/stu);
else
printf("%.2f",s/stu);
}
printf(" ");//這里要換行
for(i=0;i<stu;i++)
{
for(j=0,count=0;j<sub;j++)
if(a[i][j]>=av)
count++;
printf("%d",count);
}
printf(" ");//這里要換行
}
}
一個小錯誤，把%f寫成了%d，下次看到正常運行，還出現0就有經驗了。
還有你給出的代碼換行應該是不正確的。被輸入輸出示例誤導了。
㈣ 搞個運動會，要求有個統計分數的程序(C語言)

㈤ C語言程序，請你編寫一個程序計算每個學生的平均成績
#include<stdio.h>
void main()
{
float a[10][10];//用來存放10名學生的5門成績,最後一位用於存放平均成績
int i,j;
float sum=0.0;
for(i=0;i<10;i++)
{
printf("請輸入第%d個學生的5門成績",i+1);
for(j=0;j<5;j++)
{
scanf("%f",&a<i>[j]);
sum=sum+a<i>[j];
}
a<i>[10]=sum/5.0;
}
printf("10名學生的成績及平均分 ");
for(i=0;i<10;i++)
{
for(j=0;j<10;j++)
printf("%.3f",a<i>[j]);
printf(" ");
}
}
(5)求平均運動會成績c語言擴展閱讀：
printf的用法
格式
printf函數的原型為：
#include<stdio.h>
int printf(const char*format,...);
在講每一個函數的時候都會先把它的函數原型寫出來，這個原型你們現在看不懂不要緊，等到學完C語言之後再來看這個原型就會發現它是很有參考意義的！它對深刻理解函數有著很大的價值。
printf的格式有四種：
1)printf("字元串 ");
#include<stdio.h>
int main(void)
{
printf("Hello World! ");// 表示換行
return 0;
}
其中 表示換行的意思。它是一個轉義字元，前面在講字元常量的時候見過。其中n是「new line」的縮寫，即「新的一行」。
此外需要注意的是，printf中的雙引號和後面的分號必須是在英文輸入法下。雙引號內的字元串可以是英文，也可以是中文。
2)printf("輸出控制符"，輸出參數);
純文本復制
#include<stdio.h>
int main(void)
{
int i=10;
printf("%d ",i);/*%d是輸出控制符，d表示十進制，後面的i是輸出參數*/
return 0;
}
㈥ c語言如何循環結構編程求若干成績平均值
#include <stdio.h>main()
{
int i = 0;
float t, ave = 0; scanf("%f", &t );
while( t > 0 && t <= 100)
{
ave += t;
i++;
scanf("%f", &t );
} ave /= i; printf( "ave = %.2f\n", ave );
}
