How do I compare a charecter from a file with another character? |
I've tried:
char ch;
ifstream fin("today.txt"); // open input file
while (fin.get(ch)) {
if (ch == "z")
cout << ch;}
fin.close();
but get the error
ISO C++ forbids comparison between pointer and integer
How do I work around this issue?
Thanks,
Jonathan

Compare with a character.
if(ch == 'z')

If you want to compare a character with a character, you need to
use
if (ch == 'z')
"z" is a _string_literal_ and not a _character_.
cout << ch;}
fin.close();
but get the error

By reading the right books. What book are you reading that doesn't
explain the difference between 'z' and "z"?

watch out for 'z' in if (ch == 'z')
