Deleting spaces

[foncused]

I want to delete white space in a file without using isspace or skipws.

Code so far:

char next_symbol;
while (in_stream)
{
in_stream.get(next_symbol);
putchar (toupper(next_symbol));
}

So I think I need to add in the brackets " if (next_symbol == ' ') then cout << something that would remove that white space. I would need to leave one white space between each word though. Any ideas how to code this?

Thanks Pan, that is a bit too advanced for me where I am currently holding in class. I was thinking more along the lines of: if (next_symbol == ' ') cout << '\b';

Problem is, this deletes all white spaces and text is unreadable. What I would like to do is if (next_symbol == ' ') and then use && to ask if the next "next_symbol" is also a space (' '), if this is True then it should delete the spaces. Otherwise it will just cout the "next_symbol"

Use a simple state machine. Keep a boolean variable that is set to true if the last character read was a space or
false otherwise. Then, when you read a space, you output it only if the variable is false.

In which case, you wnat to remove repeated spaces.

You just need to remember the last character and only do the compare if it is not a space.
