Question

在我构建项目之后，我似乎收到了这条消息，表示我的程序Cyber Dojo 1已停止工作。如下所示：

现在网上有一些资源，包括：

This SO帖子，其中有一个答案尚未被接受。答案是无效的，因为我对我的程序没有任何论据。
This论坛在Eclipse社区论坛上发布。这有一些很好的建议，特别是与改变MinGW的链接器标志有关的建议。但是，这适用于C ++程序而不适用于C程序。 This也是一个处理相同问题的帖子，但对C ++来说也是如此。

这就是为什么我目前正在为我的Eclipse CDT上的C程序寻找解决此问题的方法。

这是我的代码：

     //Checking number as input
     static void isNotValidCharacter1(void)
     {
        assert(answer('3') == NULL);
     }

//Checking special character
static void isNotValidCharacter2(void)
{
    assert(answer('!') == NULL);
}

//Checking lowercase letter
static void isNotValidCharacter3(void)
{
    assert(answer('c') == NULL);
}


static void validCharacter(char **sample_answer)
{
    int i, j;
    for (i = 1; i < 11; i++) {
        for (j = 1; j < 11; j++) {
            assert((answer('F'))[i][j] == sample_answer[i][j]);
        }
    }
}

//Random Number Corner Checks Follow:

// Randomly creates a number/ character and checks the leftmost and rightmost corner characters
// as the character itself

static char psuedoRandomNumberGeneratedCharacterCheck1(void)
{
    // Creating the random number between 65 and 90
    int rn;
    srand(time(NULL));
    rn = (rand() % 25) + 65;
    int distA = rn - 65;

    //converting it to a character
    char c_rn = (char)rn;
    //checking the leftmost and rightmost corner characters
    assert(answer(rn)[distA][0] == c_rn);
    assert(answer(rn)[distA][distA*2] == c_rn);
    return c_rn;
}

// Randomly creates a number/ characters and the checks the uppermost and lowermost corner characters
// corners as 'A'

static char psuedoRandomNumberGeneratedCharacterCheck2(void)
{
    // Creating the random number between 65 and 90
    int rn;
    srand(time(NULL));
    rn = (rand() % 25) + 65;
    int distA = rn - 65;

    //converting it to a character
    char c_rn = (char)rn;
    //checking the uppermost and lowermost corner characters
    assert(answer(rn)[0][distA] == 'A');
    assert(answer(rn)[distA*2][distA] == 'A');
    return c_rn;
}

static void validCharacterA(void)
{
    char **aDiamond = answer('A');
    aDiamond[0][0] = 'A';
}

int main(void)
{
    //Not valid character tests
    isNotValidCharacter1();
    puts("Number not accepted");
    puts("special pause for debugging");
    isNotValidCharacter2();
    puts("Special Character not accepted");
    isNotValidCharacter3();
    puts("lowercase not accepted");

    //Psuedorandom Tests

    char prc1 = psuedoRandomNumberGeneratedCharacterCheck1();
    printf("random character '%c' chosen and the leftmost and rightmost corner characters", prc1);
    char prc2 = psuedoRandomNumberGeneratedCharacterCheck2();
    printf("random character '%c' chosen and the leftmost and rightmost corner characters", prc2);

    // Acid Test for the letter 'F'

    //Square of 11 letters declared
    char **Fanswer = malloc(11 * sizeof(*Fanswer));
    int i;
    for (i =0; i  <11; i++) {
        Fanswer[i] = malloc(11 * sizeof(char));
    }

    strcpy( Fanswer[0], "     A     ");
    strcpy( Fanswer[1], "    B B    ");
    strcpy( Fanswer[2], "   C   C   ");
    strcpy( Fanswer[3], "  D     D  ");
    strcpy( Fanswer[4], " E       E ");
    strcpy( Fanswer[5], "F         F");
    strcpy( Fanswer[6], " E       E ");
    strcpy( Fanswer[7], "  D     D  ");
    strcpy( Fanswer[8], "   C   C   ");
    strcpy( Fanswer[9], "    B B    ");
    strcpy(Fanswer[10], "     A     ");

    validCharacter(Fanswer);
    puts("answer for F is correct");

    validCharacterA();
puts("Answer for A is correct");

    //All tests have passed and the end of the program
    puts("All tests passed");
}

我的answer()程序如下：

char** answer(char c)
{

    if (check(c)) {
        printf("\n");
    } else {
        printf("Not a valid character\n");
        return NULL;
    }

    //   Preprocessing
    //--------------------------------------------------------------------------------------------------------

    //processing declarations
    int ascii = (int)c;
    int distA = ascii - 'A';

    //Number of Rows and Columns
    int n = ( distA * 2 ) + 1;

    //Declare the column of pointers
    char **diamond = malloc(n * sizeof(*diamond));

    //Declare the row of characters
    // 2D array declared here to save on computation in situations where characters are not valid
    int i;
    for (i=0; i<n; i++) {
            diamond[i] = malloc(n * sizeof(char));
    }

    //--------------------------------------------------------------------------------------------------
    //   Processing
    //--------------------------------------------------------------------------------------------------

    //Fill in the Array
    if (n == 1) {
        diamond[0][0] = c;
    } else {
        diamond[distA][0] = c;
        diamond[distA][distA*2] = c;
        for (i = 1; i <= distA; i++) {
            diamond[distA-i][i] = (char)(ascii - i);
            diamond[distA-i][(distA*2)-i] = (char)(ascii - i);
            diamond[distA+i][i] = (char)(ascii - i);
            diamond[distA+i][(distA*2)-i] = (char)(ascii - i);
        }
    }

    //-------------------------------------------------------------------------------------------------
    //   Postprocessing
    //---------------------------------------------------------------------------
    return diamond;
}

如果您是Eclipse的初学者并且您不知道如何使用调试器，那么您可以查看一些教程。

https://www.youtube.com/watch?v=azInZkPP56Q

但即使在本教程之后你也很难让你的debuger工作（因为有时它取决于你的Eclipse，你的编译器和其他东西的安装方式），你可以尝试将大部分代码放在注释中，看看是否问题消失了。并逐渐减少您发表评论的代码量。当bug重新出现时，这意味着它最近在你删除评论的部分内部。

最后一种方法不是调试程序的最佳方法，但对于初学者来说可能很有用，如果您使用调试器有困难，可以为您提供另一种选择。
