c - 将收获的苹果存储到库存中

有人可以帮我每天将收获的苹果存储到库存中吗，收获增加一天后，每天只能收获一次。

到目前为止，这是我的代码

void dispMenu();

int main() {
    int choice = 0;
    int apple = 0, stocks, days = 1;

menu:
    clrscr();
    printf("Day %d\n", days++);
    dispMenu();

    scanf("%d", &choice);

    if (choice == 1) {
        printf("Enter Number of apples harvested: ");
        scanf("%d", &apple);
    }

    stocks = apple;

    if (choice == 2) {
        printf("Day    Stocks\n");
        printf("%2d     %4d\n", days, stocks);
    }
    getch();
    goto menu;
}

void dispMenu() {
    printf("1. harvest\n");
    printf("2. View Stocks\n");
    printf("\nchoice: ");
}

例如：

Day 1 I input in harvest is 200
Day 2 I input in harvest is 150
Day 3 I input in harvest is 350
...days are infinite

查看股票时应显示

 DAY   STOCKS
  1     200
  2     150
  3     350

最佳答案

您应该将stocks初始化为0，然后将其增加收获的数量，而不仅仅是设置它。为了使列表每天保持一行，您需要一个数组。

您还应该将goto替换为循环：

#include <stdio.h>

void dispMenu(void) {
    printf("1. harvest\n");
    printf("2. View Stocks\n");
    printf("\nchoice: ");
}

int main(void) {
    int choice = 0;
    int apple = 0, days = 1;
    int stocks[100] = { 0 };

    for (;;) {
        clrscr();
        printf("Day %d\n", days);
        dispMenu();

        if (scanf("%d", &choice) != 1)
            break;

        if (choice == 1 && days < 100) {
            printf("Enter Number of apples harvested: ");
            scanf("%d", &stocks[days]);
            days++;
        }
        if (choice == 2) {
            printf("Day    Stocks\n");
            for (int i = 1; i < days; i++) {
                printf("%2d     %4d\n", i, stocks[i]);
        }
        getch();
    }
    return 0;
}
