ปัญหา

โปรแกรมมีตัวเลขคงที่อยู่แล้ว ผู้ใช้ต้องทายเลขนั้น โดยให้คำใบ้ทุกครั้งที่ทาย

วิธีแก้ปัญหา

ตรรกะการทายเลข:

do {
    if(num == guess) {
        flag = 0;
    } else if(guess < num) {
        flag = 1;
        printf("Your guess is lower than the number\n");
        count++;
    } else {
        flag = 1;
        printf("Your guess is greater than the number\n");
        count++;
    }
    if(flag == 1) {
        printf("sorry wrong enter! once again try it\n");
        scanf("%d", &guess);
    }
} while(flag);

ตัวอย่างโค้ด

#include <stdio.h>

int main() {
    int i, num = 64, flag = 1, guess, count = 0;
    printf("guess the number randomly here are some clues later\n");
    scanf("%d", &guess);
    do {
        if(num == guess) {
            flag = 0;
        } else if(guess < num) {
            flag = 1;
            printf("Your guess is lower than the number\n");
            count++;
        } else {
            flag = 1;
            printf("Your guess is greater than the number\n");
            count++;
        }
        if(flag == 1) {
            printf("sorry wrong enter! once again try it\n");

        }
    } while(flag);
    printf("Congratulations! You guessed the correct number %d\n", num);
    printf("Total number of trails you attempted for guessing is: %d\n", count);
