函数ReadDat()实现从IN.DAT文件中读取一篇英文文章并存入到字符串数组xx中。请编写函数encryptChar()，按给定的替代关系对数组xx中的所有字符进行替代后，仍存入数组xx的对应位置上，最后调用函数WriteDat()，把结果xx输出到OUT.DAT文件中。
替代关系：f(p)=p*11 mod 256(p是数组中某一个字符的ASCII值，f(p)是计算后新字符的ASCII值)，如果计算后f(p)值小于等于32或f(p)对应的字符是大写字母，则该字符不变，否则将f(p)所对应的字符进行替代。
原始数据文件存放的格式是：每行的宽度均小于80个字符。
注意：部分源程序已经给出。
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。
#include＜stdio.h＞
#include＜string.h＞
#include＜conio.h＞
#include＜ctype.h＞

void WriteDat(void)

for(i=0; i＜maxline;i++)

printf("%s\n",xx[i]);
