Palindrome- error in in statement

Victor Soldera 2020-07-24 06:53:32

Hey! I'm having a problem in an if statement. It seems to be ignoring all other conditions other than string[j] != ' ';

//Here is the problem! It ignores all other conditions, and if I take them away(other them != ' ', it works
if(string[j] != ' '  || string[j] != ',' || string[j] != '!' || string[j] != '-') {
    aux[count++] = tolower(string[j]);
}

Thanks for your help!

Victor, Hi!

The problem is not in the code, but in the logic which you invented. You say

if character is not space OR is not comma OR...

But it is true for any character. If it is not space then c != ' ' is true, but if it is space, then c != ',' is true. So your condition is always true, that's how OR works.

I leave this to figure out further to yourself, if you don't mind :)
