Reading in spaces.

tomtom61695 (29)
Below isn't the full code but it is where my problem is. I am trying to read in an input file, remove the vowels, and then output it. I am running into the problem where the spaced aren't being read into the array and I don't know how to get around it. I know I can use getline(), but I don't know how to use it where I can edit each character like I want to. My output file is just a bunch of weird characters. Help would be very much appreciated!

    int i = 0;
    int x = 0;
    string space = ' ';
    while (!input.eof()){
        input >> holding[i];
        i++;
        
        if (holding[x] == 'A' || holding[x] == 'a' ||holding[x] == 'E' ||
            holding[x] == 'e' || holding[x] == 'I' || holding[x] == 'i' ||
            holding[x] == 'O' || holding[x] == 'o' || holding[x] == 'U' ||
            holding[x] == 'u' || holding[x] == 'Y' || holding[x] == 'y'){
            x++;
        }
        if(holding[x] == ' '){
            output << space;
            x++;
        }
        else{
            output << holding[x];
            x++;
        }
        
    }
}

I did not look at your problem to close.
could you provide a complete example that demonstrates your problem in program that compiles?

Ignore the last function.
