函数里的数组

[人海迷航]

请问下面这个简单的程序，错在哪里？
输入Ｎ个学生的四门功课的成绩，然后打印出来。

//随意输入N个学生的成绩，每个学生有四门课程
//如果输入0,0,0,0则表示输入结束
void read(int score[][4],int n){
    //int score[][4];
    int number = 0;
    for(;;){
        if(number > 0){
            if(score[number-1][0] == 0 || number >= n)
            break;
        }
        scanf("%f,%f,%f,%f",&score[number][0],&score[number][1],&score[number][2],&score[number][3]);
        number++;
    }
    printf("you've input %d student's scores!\n",number);
    int i = 0;
    for(i = 0; i < number; i++)
    {
        printf("row[%d]:%f,%f,%f,%f\n",i+1,score[i][0],score[i][1],score[i][2],score[i][3]);
    }
}
main(){
    int num = 0;
    int s[1000][4];
    printf("input the total students you need to input:");
    scanf("%d",&num);
    printf("input scores:\n");
    read(s,num);
}

scanf("%d%d%d%d",&score[number][0],&score[number][1],&score[number][2],&score[number][3]);
printf("row[%d]:%d %d %d %d\n",i+1,score[i][0],score[i][1],score[i][2],score[i][3]);

你的数组是int型

综合上面各位的意见，把数组改成double型，加上fflush函数，问题依然存在。

#include <stdio.h>
//随意输入N个学生的成绩，每个学生有四门课程
//如果输入0,0,0,0则表示输入结束
void read(double score[][4],int n){
    //int score[][4];
    int number = 0;
    for(;;){
        if(number > 0){
            if(score[number-1][0] == 0 || number >= n)
            break;
        }
        scanf("%f,%f,%f,%f",&score[number][0],&score[number][1],&score[number][2],&score[number][3]);
        fflush(stdin);
        number++;
    }
    printf("you've input %d student's scores!\n",number);
    int i = 0;
    for(i = 0; i < number; i++)
    {
        printf("row[%d]:%.2f,%.2f,%.2f,%.2f\n",i+1,score[i][0],score[i][1],score[i][2],score[i][3]);
    }
}
main(){
    int num = 0;
    double s[1000][4];
    printf("input the total students you need to input:");
    scanf("%d",&num);
    printf("input scores:\n");
    read(s,num);
    system("pause");
    return 0;
}

scanf("%f,%f,%f,%f",&...........)
是你输出数据的时候错了吧.
看到上面的%f旁边的,号没有.
输出的时候数据间隔要加,号
比如
12,56.88,56,78

[人海迷航]

%.2f这样的格式是表示保留2位小数，没有问题吧？

#include<stdio.h>
void read(float score[][4],int n)//改为float型的了
{
    //int score[][4];
    int number = 0;
    for(;;)
	{
        if(number > 0)
		{
            if((score[number-1][0]-0)<0.00001 || number >= n)//float型的数与0比较要注意
            break;
        }
        scanf("%f,%f,%f,%f",&score[number][0],&score[number][1],&score[number][2],&score[number][3]);

    }

double跟float搞混了，对不起各位。

//如果输入0,0,0,0则表示输入结束
if(score[number-1][0] == 0 || number >= n)
break;
这里,如果第一个为0其实就退出了.
