#define N 4
#include "stdio.h"
main()
{
    char name[N][9];
    int mark[N][3],sum[N];
    int i,j;
   
    printf("请输入每个学生的名字及每门课程的成绩。以回车结束\n");
    printf("%10s%10s%10s%10s\n","学生名字","高等数学","大学英语","C语言");
    for(i=0;i<N;i++)
    {
        sum[i]=0;
        gotoxy(4,3+i);
        gets(name[i]);
        for(j=0;j<3;i++)
        {
            gotoxy(8+(j+i)*10,3=i);
            scanf("%d",&mark[i][j]);
            sum[i]=sum[i]+mark[i][j];
            }
    }
    printf("\n%10s%10s%10s\n","学生名字","总成绩","平均成绩");
    for(i=0;i<N;i++)
    {
        printf("%10s%10d%10.2f\n",name[i],sum[i],sum[i]/3.0);
        }

   
}

其中      printf("%10s%10s%10s%10s\n","学生名字","高等数学","大学英语","C语言");
这语句是什么意思。谢谢、

为什么我用 C与C++程序设计学习与实验系统 也不行.
