/******************************************************** * guess -- a simple guessing game * * * * Usage: * * guess * * * * A random number is chosen between 1 and 100. * * The player is given a set of bounds and * * must choose a number between them. * * If the player chooses the correct number he wins* * Otherwise the bounds are adjusted to reflect * * the player's guess and the game continues. * * * * * * Restrictions: * * The random number is generated by the statement * * rand() % 100. Because rand() returns a number * * 0 <= rand() <= maxint this slightly favors * * the lower numbers. * ********************************************************/ #include #include /* ANSI Standard only */ int number_to_guess; /* random number to be guessed */ int low_limit; /* current lower limit of player's range */ int high_limit; /* current upper limit of player's range */ int guess_count; /* number of times player guessed */ int player_number; /* number gotten from the player */ char line[80]; /* input buffer for a single line */ main() { while (1) { /* * Not a pure random number, see restrictions */ number_to_guess = rand() % 100 + 1; /* Initialize variables for loop */ low_limit = 0; high_limit = 100; guess_count = 0; while (1) { /* tell user what the bounds are and get his guess */ (void) printf("Bounds %d - %d\n", low_limit, high_limit); (void) printf("Value[%d]?
