己知数据文件IN57.DAT中存有300个4位数，并已调用读函数readDat()把这些数存入数组a中，请编制一函数jsValue()，其功能是：求出个位数上的数减千位数上数减百位数上的数减十位数上的数大于零的个数cnt，再把所有满足此条件的4位数依次存入数组b中，然后对数组b的4位数按从大到小的顺序进行排序，最后调用函数writeDat()把数组b中的数输出到OUT57.DAT文件中。
例如: 1239，9—1-2-3＞0，则该数满足条件，存入数组b中，且个数cnt=cnt+1。
8129，9-8-1-2＜0，则该数不满足条件，忽略。
注意：部分源程序已给出。
程序中已定义数组：a[300)，b[300]，已定义变量：cnt。
请勿改动主函数main()、读函数readDat()和写函数writeDat()的内容。
试题程序：
#include＜stdio.h＞
int a[300],b[300],cnt=0;jsValue()
main ( )

int i;
readDat();
jsValue();
writeDat();
printf ("cnt=%d\n", cnt);
for(i=0;i＜cnt;i++)
print f ("b [%d] =%d\n", i,b Iii );

readDat ( )

FILE *fp;
int i;
fp=fopen ("IN57 .DAT", "r");
for (i=0; i＜300; i++)
fscanf (fp, "%d, ",&a [ii );
fclose(fp);
writeDat ()

FILE *fp;
int i;
fp=fopen "OUT57. DAT", "w" );
fprintf (fp, "%d\n", cnt);
for (i=0; i＜cnt; i++)
fprintf(fp, "%d\n",b[i]);
fclose (fp);
