☆ 题目2
已知数据文件in.dat中存有200个四位数，并已调用读函数readdat()把这些数存入数组a中，请考生编制一函数jsval()，其功能是：如果四位数各位上的数字均是0或2或4或6或8，则统计出满足此条件的个数cnt，并把这些四位数按从大到小的顺序存入数组b中。后main( )函数调用写函数writedat()把结果cnt以及数组b中符合条件的四位数输出到out.dat文件中。
注意：部分源程序存在文件prog1.c中。
程序中已定义数组：a[200]，b[200]，已定义变量：cnt
请勿改动数据文件in.dat中的任何数据、主函数main()、读函数readdat()和写函数writedat()的内容。

&emspdefine max 200
int a[max], b[max], cnt = 0 ;

for(i=0;i { qw=a[i]/1000; bw=a[i]/100;
sw=a[i]0/10; gw=a[i];
if(qw
}
for(i=0;i for(j=i+1;j if(b[i]}
