writting to a folder, and editing strings

**Dark Nemesis** · 08-16-2003

alright, I have two problems, first of all I want to write to a folder, the folder is predetermined (not a variable), but the file name is a variable, but I want it to write to: saves\command.svg
command is the character string (variable)

I tried:
strcpy(command,"saves\",command,".svg");

edit> nm gotit, sorry, strcat fixed it

edit2> it outputs a file testest, I set command to test and ran these before opening the file:
[CODE] strcat("saves\\",command);
strcat(command,".svg");[\CODE]

I used:
ofstream load(command);
to open the file, but it didn't work

You can only use strcat on non-constant strings. (String literals are constant, and they're anything like "this". )

this generates a file with no extention in the programs directory, not under saves

Code:

int loadchar(int charid, char command[8]) {
	char file[20];

	strcpy(file,"saves\\");
	strcat(file,command);
	strcat(file,".svg");

	ofstream load(command);

	load << "test";

	load.close();
	return 0;
}

any help?

You're supposed to use 'file' in the ofstream, not 'command'

I just noticed that, but thank-you, I feel really dumb now...
here's a new question: deleting from strings, how is it done?

Can you be a bit more specific ? Give an example or something.

sure, like if I wanted to delete the last few characters in a string if I know what the characters are, but no the lenght, what would I use? I though about a loop to check each individual character in the string, and then find where the null character is, then rewrite the string with the deletion, is there an easier way?

Here you can find some methods for nul-terminated string.

It's easier to use a string variable. Here you can find some usefull methods.
