试题说明 :
===============================================================================
 已知在文件IN.DAT中存有若干个(个数<200)四位数字的正整
数, 函数ReadDat( )是读取这若干个正整数并存入数组xx中。请
编制函数CalValue( ), 其功能要求: 1. 求出这文件中共有多少
个正整数totNum; 2. 求这些数中的千位数位置上的数字与十位
数位置上的数字均为的奇数的个数totCnt, 以及满足此条件的这
些数的算术平均值totPjz, 最后调用函数WriteDat()把所求的结
果输出到文件OUT10.DAT中。
 注意: 部分源程序存放在PROG1.C中。
 请勿改动主函数main( )、读数据函数ReadDat()和输出数据
函数WriteDat()的内容。
