Question

Exercise 1: A Game of guessing number Set the default upper and lower limits to be 1-100, and ask you to guess a number. If you do not guess the correct number, the program will nicely" automatically adjust the upper or the lower limits to save your day until you guess it. 2 0 12. 51 - 100 3 2 51 74 22 65 74 85 2 71 74 3 . 2 73 74 75 2 73 73 SC -> 75 -> 64 -> 70 -> 72 ==> 74 --> 73 Exercise 2: A Game of Chance: One of the most popular games of chance is a dice game known as "craps. The rules of the game are simple. A player rolls two dice. Each die has six faces. These faces contain 1, 2, 3, 4, 5, and 6 spots. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, the player wins. If the sum is 2, 3, or 12 on the first throw (called "craps), the player loses (i.e., the "house" wins). If the sum is 4,5,6,8,9, or 10 on the first throw, then that sum becomes the player's point." To win, you must continue rolling the dice until you make your point. The player loses by rolling a 7 before making the point. Use the function → dello prayer roed d edeledel

Answer 1

EXERCISE 1

#include <stdio.h>
#include <time.h>

int main(void)
{
   int randNum, guessNum;
   int lower = 1, upper = 100;
  
   srand(time(NULL));
   randNum = rand() % 100 + 1;
  
   while(1) {
       printf("Enter guess betweem %d ~ %d: ", lower, upper);
       scanf("%d", &guessNum);
      
       if(guessNum == randNum) {
           printf("\n\nCorrect guess.\n");
           break;
       }
       else if(guessNum > randNum)
           upper = guessNum;
       else
           lower = guessNum;
       printf("Not correct. try again...\n");
   }
  
   return 0;
}

OUTPUT:

Enter guess betweem 1 - 100: 50 Not correct. try again... Enter guess betweem 50 - 100: 56 Not correct. try again... Enter guess betweem 56 - 100: 78 Not correct. try again... Enter guess betweem 56 - 78: 65 Not correct. try again... Enter guess betweem 65 - 78: 68 Not correct. try again... Enter guess betweem 68 - 78: 72 Not correct. try again... Enter guess betweem 72 - 78: 75 Not correct. try again... Enter guess betweem 72 - 75: 73 correct guess. Process exited after 33.91 seconds with return value o Press any key to continue ....
