c - 在 C 中没有全局变量或更改函数输入的情况下对函数内部数组的变量赋值

Question

我有一组特定的约束。如果没有约束，这个问题并不难。

    #define ROW 12
    #define COL 6   

    int main (void)
    {
    // Code can be changed in brackets
        char arr[ROW][COL];
        function1(arr);
        printf("%s", arr[0][0]); 
    }


    void function1(char arr[][COL]){  //Can't change anything in this line
    // Code allowed to be changed inside brackets
    // Trying to assign values to multi-dim array as shown below
        arr[0][0] = 'O';
    }

Process finished with exit code -1073741819 (0xC0000005)

更改arr[0][0] = "O";至 arr[0][0] = 'O';

在 printf("%s", arr[0][0]); //<-----should be %c 中指定正确的格式

#define ROW 12
#define COL 6   

    int main (void)
    {
    // Code can be changed in brackets
        char arr[ROW][COL];
        function1(arr);
        printf("%c", arr[0][0]); //<----------- should be %c
    }


    void function1(char arr[][COL]){  //Can't change anything in this line
    // Code allowed to be changed inside brackets
    // Trying to assign values to multi-dim array as shown below
        arr[0][0] = 'O';
    }
