C - 輸出值計算不正確

Question

我剛剛開始學習如何編寫代碼並決定嘗試創建一個程序，該程序可以基於某些要求的值來計算人們燃燒的卡路里量。然而，每當我運行它而不是基於它們的值獲取計算值時，我總是得到值2686708.無論如何，我似乎無法使它工作。

//included libraries 
    #include <stdio.h> 
    #include <stdlib.h> 
    #include <math.h> 

//constants 
#define WALKING_CAL 5 
#define EXERCISING_CAL 10 
#define EATING_CAL 40 
#define DRINKING_CAL 20 
#define CALORIES_PER_POUND 3500*/ 

//main function 
int main() { 

int current_weight, goal_weight; 
int walking, exercise, drinking, eating; 
int total_walking, total_exercising, total_eating, total_drinking; 
int calories_burned, calories_gained; 

printf("What is your current weight?\n"); 
scanf("%d", &current_weight); 

printf("\nWhat is your goal weight?\n"); 
scanf("%d", &goal_weight); 

total_walking = WALKING_CAL * walking; 
total_exercising = EXERCISING_CAL * exercise; 
total_eating = EATING_CAL * eating; 
total_drinking = DRINKING_CAL * drinking; 
calories_burned = (total_walking + total_exercising)- (total_eating + total_drinking); 


if (goal_weight > current_weight){ 
    printf("\nHow many minutes do you walk per day?\n"); 
    scanf("%d", &walking); 

    printf("\nHow many minutes do you exercise per day?\n"); 
    scanf("%d", &exercise); 

    printf("\nHow many minutes do you drink per day?\n"); 
    scanf("%d", &drinking); 

    printf("\nHow many minutes do you eat per day?\n"); 
    scanf("%d", &eating); 


    printf("You gain %d calories per day.", &calories_burned); 

    } 
    return 0; 
} 

Answer 1

此：

printf("You gain %d calories per day.", &calories_burned); 

打印變量的地址，而不是變量的值（爲int，這又是不確定的行爲，但似乎並不適合你至少炸燬）。

它應該是：

printf("You gain %d calories per day.", calories_burned); 

刪除該&。
