c - 骰子游戏程序不会运行，但不会在掷 5 次时停止

Question

我收到两个错误:

Error 3 error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup

和:

Error 4 error LNK1120: 1 unresolved externals

由于我无法让程序运行，我也不确定案例“A”是否会产生掷骰子。我不想显示案例“A”中的结果，我的直觉是 scanf不应该在那里，但我可能是错的。

这是我的代码:

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

#define PAUSE system("pause")


int main ()
{
    int diceOne, diceTwo, diceThree;
    int currentDiceSum=0, totalDiceSum=0;
    char choice;
    int count = 0;

    srand((unsigned)time(NULL));

    diceOne      =rand()%6+1;
    diceTwo      =rand()%6+1;
    diceThree    =rand()%6+1;

    do {
        printf("\n Roll the dice, but you only get 5 rolls! You can't play forever, you know. \n");

        printf("Main Menu\n");
        printf("A.Roll the Dice\n");
        printf("B.Display the Result of Last Roll\n");
        printf("C.Quit\n");

        printf("Enter your choice:   ");
        scanf(" %c", &choice);

        choice = toupper(choice);

        switch(choice) {
            case 'A': 
                printf("Dice are rolled!'\n");

                diceOne      =rand()%6+1;
                diceTwo      =rand()%6+1;
                diceThree    =rand()%6+1;


                count ++;
                break;
            case 'B':  
                if (count = 0) {
                    printf("Please roll the dice atleast once\n");
                }  else {
                    printf("Dice 1: %d\n", diceOne);
                    printf("Dice 2: %d\n", diceTwo);
                    printf("Dice 2: %d\n", diceThree);

                    currentDiceSum = diceOne + diceTwo + diceThree;
                    printf("Dice Total: %d\n", currentDiceSum);
                    totalDiceSum+= currentDiceSum;
                }
                break;
            case 'C':
                if (count == 5)  
                    printf("Number of rolls: %d\n", count);

                printf("Total of all dice for all rolls:%d\n",totalDiceSum);
                printf("Goodbye, hope to see you again!!!\n");
                PAUSE;
                break;

            default:
                printf("Was not a valid menu choice (Please enter A,B,C\n");
                break;
        }
    } while (choice!= 'C'); 
}

Answer 1

Error 3 error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup

这是链接器错误消息。

我认为您已经创建了一个 GUI Windows 应用程序，因为它需要 WinMain 作为入口点。

您应该在链接器设置中将子系统更改为控制台。

如果您使用的是 Visual Studio，请转到

项目属性然后c\c++然后链接器->system->子系统:CONSOLE(/SUBSYSTEM CONSOLE)

对于代码块 -

转到项目，然后转到属性。在构建目标选项卡下，查看组合框类型。对于调试目标，将其设置为“控制台应用程序”

此外，您的程序运行良好。它没有任何其他错误，也不会崩溃。
