Question

我为生命游戏模拟编写了一个C代码。我的程序完全适用于案例1，这是我的随机数组。但是当我尝试从.txt文件中加载数组时，它不起作用。我的意思是它给了我一个输出但它没有输出带'*'或''的数组它给了我这个：

有人知道我的错误是什么吗？

这是我的代码：

您的问题是进入load_matr函数：

这是一个可能的解决方案，它使输入文件格式正确（它不是解决方案容错），以及许多不好的事情，但它可以正常工作。

void clear_matr(char matr[ED][ZD])
{
    for (int row = 0; row < ED; row++)
        for (int col = 0; col < ZD; col++)
            matr[row][col] = ' ';
}


void load_matr(char matr[ED][ZD], int n, int m, int filenr, int *alz) {
    FILE *fp;
    char c[16];
    (*alz)=0;
    memset(c, 0, sizeof(c));

    if (filenr == 1) {
        fp = fopen("matrix1.txt", "rt"); 
    }
    else if (filenr == 2) {
        fp = fopen("matrix2.txt", "rt");
    }
    else if (filenr == 3) {
        fp = fopen("matrix3.txt", "rt");
    }

    if (fp == 0) {
        printf("Couldnt open File!");
        exit(-1);
    }

    if (fgets(c, 5, fp) == NULL) {
        printf("Error\n");
        exit(-1);
    }
    n = atoi(c);

    if (fgets(c, 5, fp) == NULL) {
        printf("Error\n");
        exit(-1);
    }
    m = atoi(c);

    clear_matr(matr);

    for (int ly = 0; ly < m; ly++) {
        for (int lx = 0; lx < n; lx++) {
            int star = fgetc(fp);
            if (star == '\n')
                star = fgetc(fp);
            if (star == 42) { //42=* | ASCII
                matr[ly][lx] = '*';
                (*alz)++;
            }
            else if (star == 32) { //32=  | ASCII
                matr[ly][lx] = ' ';
            }
            else break; //EOF
        }

    }
    fclose(fp);
}
