Help with C++ code I will up vote !!! please run before sending code

Write a C++ program that identifies and counts words and special names in a textual file. There are two kinds of special names considered, called Type 1 and Type 2 names. Counting is applied on all occurrences of words and specialized names. A word is defined as a sequence of one or more non- Whitespace characters separated by whitespace. The special names of Type 1 and Type 2 are identifi by a special character at the beginning of the name. Type 1 names must start by a 'S' character, while Type 2 names must start by @ character. All Type 1 and Type 2 names should consist of a letter following the special start character, followed by zero or more letters, digits or underscores. For example, Svalue, Qval9, \$num,234_ten, and @num_45 are valid Type 1 and Type 2 names, but \$9val, and @ _num, SnumS are not. The program may accept one or two command line arguments. The format of the command line argurnents is specified as follows: - The first argument must be a file name. - The second optional argument is for one of the following flags: - "-all": the program displays the total number of words, the number of Type 1 names, and the number of Type 2 names. - "type1": the program displays the number of Type 1 names only. - "type2": the progran displays the number of Type 2 names only. If no file name is provided, the program should print on a new line " NO SPECIFIED INPUT FILE NAME,, and exit. If the file cannot be opened, print on a new line "CANNOT OPEN THE FILE", followed by the file name, and exit. The program should read from the file lines until the end of file is found. If the input file is empty, it prints out the message "File is empty." on a new line and then exits. In case the command line does not include any of the optional flags, the program should display the total number of words, and the total of Type 1 and Type 2 names. If an optional flag argument is not recognized, the program should print out the message "UNRECOGNIZED FLAG
