CS156 HW2: Guessing Game                

Distance	Message
> 60	icy
≤ 60	cold
≤ 45	cool
≤ 30	tepid
≤ 12	quite hot
≤ 2	white hot

Description                

In this homework assignment, you will write a program called gan.c (for guess a number) that plays a guessing game. The program will pick a whole number number between 1 and 100, inclusive, and you will guess what the number is. The program will tell you how you’re doing with each guess. When you guess correctly, the program will end after telling you how many guesses it took.                 

Random Numbers                

To produce a random int between 1 and 100, do this:                 

    /* These go before main() */
    #include <stdlib.h>
    #include <time.h>

    /* These go at the beginning of main() */
    srand(time(NULL));               // Seed the random number generator
    int goal = rand() % 100 + 1;     // goal will be 1-100, inclusive

Sample Run                

In this example, the prompt is “%”. Text like this is what the user types in while running the program. Your output should match exactly.                 

    % c11 -Wall gan.c
    % ./a.out
    I've thought of a number, 1-100.
    Your guess is: 999
    999 is not 1-100.
    Your guess is: 0
    0 is not 1-100.
    Your guess is: 101
    101 is not 1-100.
    Your guess is: 1
    1 is cool.
    Your guess is: 100
    100 is icy.
    Your guess is: 40
    40 is quite hot.
    Your guess is: 50
    50 is tepid.
    Your guess is: 30
    30 is quite hot.
    Your guess is: 35
    35 is white hot.
    Your guess is: 36
    36 is correct in 10 guesses.

Notes                

• If your program doesn’t compile, you get no points.
• You must have a comment block including your name, date, and purpose of the program at the very very very beginning of the file.
• If you don’t follow the specifications provided, or your output doesn’t match exactly to the examples displayed, you will lose points.
• You may assume that the user will type an integer, when prompted to do so. However, it may not be an integer that you like.
• No global variables.
