Shawn Green made a similar mistake in the Doom source code. We will modify Doom to add our own game data... so we will copy and paste. Hmm. Without altering any string literals, fix the following code: (You will edit the existing code below) const char* doomwaddir = "/home/wilkie/doom"; char* doomwad = malloc(strlen(doomwaddir)+1+8+1); sprintf(doomwad,"%s/doom. wad", doomwaddir); char* wilkiedoomwad = malloc(strlen(doomwaddir)+1+8+1); sprintf(wilkiedoomwad,"%s/wilkdoom. wad", doomwaddir);
