I have one of those basic assignments where you need to count the numbers of specific types of characters in an input file. There are 3 files involved, the main program (which I will include below), the hopper.txt input text to be analyzed, and the sample output.txt which demonstrates what the output should look like in the command line.
I believe I have everything set but my final numbers arnt turning out correctly. Specifically, my other and total counters are about 200 over. Now I've done some counting with other programs and am pretty sure that the sample output is correct which is why I suspect that I must be counting the hidden characters (and they must be there because the output isn't just a block of text).
I've tried casting each character to an int in order to see what its ascii value is and go off of that range but my IDE (Xcode) says that "comparison of constant with expression of type 'bool' is always true", and the check doesn't seem to catch anything.
Here are the other two files:

While reading them it takes cultivates relivant data about

You can use std::isspace to test if a character is one of :
And ignore those by adding a test in your reading loop :
else if (std::isspace(ch)) {
continue; // Do not update counters
}
