c语言推理（C language reasoning） I saw an interesting logical reasoning on the Internet, and Einstein claimed that only 2% of the people in the world could solve it: There are five rooms with five different colors in a row; Each room is inhabited by a different nationality; Everyone drinks a particular brand of drink, smokes a particular brand of cigarettes, and keeps a particular pet; No two people are smoking the same brand of cigarettes, or drinking the same brand of drink, or keeping the same pets. Question: who is keeping fish for pets? Einstein gives the following clues: The English live in red houses; The Swede keeps dogs as pets; The Dane drinks tea; The green house is next to the White House, on the left of the white house; The owner of the green house drinks coffee; Pall pumping Mall cigarettes were aviculture; The people in the Yellow House smoke Dunhill cigarettes; The man living in the middle of the house drinks milk; The Norwegians live in the first house; The man who smokes the Blends brand is next to the cat; Horses are kept close to those who smoke Dunhill cigarettes; People who smoke BlueMaster cigarettes and beer; The Germans smoked Prince cigarettes; The Norwegians live next to those living in the blue house; People who smoke Blends cigarettes are next to those who drink mineral water. #includestdlib.h #include stdio.h #includestring.h Int main (void) { FILE *fp; Char data[5][40]={, country, house, pet, drink, cigarette}; Char country[6][40]={, , , , , }; Char house[6][40]={, , , , , }; Char pet[6][40]={, , , , , }; Char drink[6][40]={, , , , , }; Char smoke[6][40]={, , , , , }; Int, I, J, K, l, m, N, O, P, t, Q, R, s; Bool, A1, A2, A3, A4, A5, A6, A7, A8, A12, A9, A10, A11; If ((fp=fopen (sdfg.txt, w+)) = = NULL) { Fprintf (stderr, \nError, opening, file, \n); Exit (1); } Strcpy (country[1], Norway); / / the Norwegian lives in the first house Strcpy (house[2], blue); Strcpy (drink[3], milk); / / the man living in the center house to drink milk For (i
