请编制程序，要求：将文件IN92.DAT中的200个整数读入数组xx中，求出数组xx中最大数max及最大数的个数ont和数组xx中值能被3整除或能被7整除的数的算术平均值pj(保留两位小数)，结果max， cnt，pj输出到out92.dar中。
部分程序、读函数read_dat(intxx[200])及输出格式已给出。
试题程序：
#include＜conio.h＞
#include＜stdi0.h＞
#define N 200
void read_dar(int xx[N])

int i,j;
FILE *fp;
fp=fopen("IN92.DAT","r");
for(i=0;i＜20;i++)

for (j=0； j＜10; j++)

fscanf(fp,"%d,",&xx[i*10+j]);
printf("%d",xx[i*10+j]);

printf("\n");

fclose fp);


void main,

int i,k,cnt,xx[N],max;
float pj;
FILE *fw;
long j=0;
clrscr();
fw=fopen("out92.dat","w");
read_dat(xx);
printf("\n\nmax=%d,cnt=%d,pj=%6.2f\n",max, cnt,pj
fprintf(fw,"%d\n%d\n%6.2f\n",max,cnt,pj);
fclose(fw);
printf("\n");

fclose fp);


void main,

int i,k,cnt,xx[N],max;
float pj;
FILE *fw;
long j=0;
clrscr();
fw=fopen("out92.dat","w");
read_dat(xx);
printf("\n\nmax=%d,cnt=%d,pj=%6.2f\n",max, cnt,pj
fprintf(fw,"%d\n%d\n%6.2f\n",max,cnt,pj);
fclose(fw);

SOX is an alternative（1）for XML. It is useful for reading and creating XML content in a（2）editor. It is then easily transformed into proper XML. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML（3）have not reached a point where their tree views, tables and forms can completely substitute for the underlying（4）language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java. SOX uses（5）to represent the structure ofan XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.
