函数fun的功能是：将s所指字符串中ASCII值为奇数的字符删除，串中剩余字符形成一个新串放在t所指的数组中。

例如，若s所指字符串中的内容为：〞ABCDEFG12345〞,其中字符A的ASCII码值为奇数、…、字符1的ASCII码值也为奇数、…都应当删除，其它依此类推。最后t所指的数组中的内容应是：〞BDF24〞。

注意：部分源程序存在文件PROG1.C中

请勿改动主函数main和其它函数中的任何内容，仅在函数fun的花括号中填入你编写的若干语句

-Function fun feature is: s referred to an odd string of ASCII characters is removed, the remaining character string to form a new string on the t refers to the array. For example, if the contents of the string s referred to as: " ABCDEFG12345" , in which character A, ASCII code is odd, ..., character 1, ASCII code value is odd, ... should be removed, the other and so on. T refers to the final contents of the array should be: " BDF24" . Note: Some source code changes do not exist in the file PROG1.C main function and other functions in any content, only the braces in the function fun fill you write a number of statements
