I$\text{'}$m having issues with this prompt below. I included my code and can only pass $4/8$ test cases$/$ Fix the other $4$ test cases without failing the first $4$ asap. THanks.

Prompt:

Write a C$++$ program that accepts one command line argument for a file name, and ignores any extra command line arguments that may be provided after the first one. 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.

The program should count the number of lines, the number of non$-$blank lines, the number of words that contain $5$ or less characters, the number of words that contain more than $5$ characters, the number of names $($special names$),$ and the number of unsigned integers, seen in the file.

A word is defined as a sequence of one or more non$-$whitespace characters separated by whitespace. A word is defined as a name if it starts by a letter and followed by zero or more letters, digits, underscores $\_,$ or $$@$$ characters. For example, value, val@l$9,$ num$234$ten are valid names, but $9$val, $\_$num$\_45$ and @num are not. A word is defined as an unsigned integer if it starts by a digit and followed by zero or more digits $($ignoring signed integers$).$ For example, $2345$ is an unsigned integer word, while $44\mathrm{.}75,-345$ and $4$today$45$ are not unsigned integers. Note that a line having only whitespace characters is a non$-$blank line as well.
