Is there a way to insert a define constant into the middle of a quoted string at compile time? I have some site-dependent menu headers and am always annoyed when I have to "sprintf" them before using them. #define SITE "Ames Research" char title2[] = " - Fancy Title"; char title[80]; sprintf(title, "%s%s", SITE, title2); domenu(title); The pre-processor should have something that helps. Please repond via mail. Chuck Collins cpc@ames-nas {ihnp4,hplabs}!ames!amelia!cpc

Since the proposed ANSI standard allows things like #define FOO "bar" #define BAR "foo" char baz[] = FOO " the " BAR; I thought I'd take the opportunity to post this little program I wrote ages ago. ----------------------------------------------------------------------- static char sccsid[] = "@(#)string.c U of Maryland ACT 30-Oct-1982"; /* string -- combine adjacent C strings */ #include <stdio.h> #define SQUOTE '\'' #define DQUOTE '"' #define BACKSLASH '\\' main () { register c; register char *p, *q; char buf[BUFSIZ]; while ((c = getchar ()) != EOF) { top: if (c == SQUOTE) { putchar (c); while ((c = getchar ()) != EOF) { putchar (c); if (c == BACKSLASH) putchar (getchar ()); else if (c == SQUOTE) break; } } else if (c == DQUOTE) { putchar (c); more: while ((c = getchar ()) != EOF) { if (c == BACKSLASH) { putchar (c); putchar (getchar ()); } else if (c == DQUOTE) break; else putchar (c); } p = q = buf; while ((c = getchar ()) == ' ' || c == '\t' || c == '\n') *p++ = c; if (c == DQUOTE) goto more; putchar (DQUOTE); while (q < p) putchar (*q++); goto top; } else putchar (c); } } -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 4251) UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
