Show activity on this post. How would I declare a pointer which points to 2D array of character pointers. Like char *ar[10][10]; In my understanding this array is stored as array of array, so ar points to a array of pointers, each of which points to a column in this array. So ...
Technically, nowarray_nameis declared as anarray ofnum_rowspointerstoint, not arrays. To "complete" the "2D array", one should traverse the array and allocate memory for each row. Note that the rows could have different sizes. Using this form: int(*array_name)[num_columns];// ^ ^ no...
we change the value at address pointer by ‘ptr’. But if this would have been a pointer to a constant, then the last line would have been invalid because a pointer to a constant cannot change the value at the address its pointing to. ...
shared_ptr不能指向数组吧？我记得C++ primer里还特别强调过（见C++ primer 第五版 426页）unique_ptr可以，上面指向一维数组的话是这么写的，unique_ptr<T[]> u(p) 其中u指向内置指正p指向的动态分配的数组，p必须能转换为类型T*，也就是p指向int*的话T[]就应该是int[]。而且智能指针只能指向...
I am still new to C++, please excuse any silly mistakes i make. I'm trying to make a simple game where i use 2D arrays as maps. To make multiple maps I'm trying create a pointer to a 2D array. This is an example of what I'm trying to do: 123456789101112131415161718...
so with the initBoard and printBoard functions, I'm trying to pass A 2D char array by pointer to these functions I got the solution from stackoverflow. but I don't understand the syntax why is the * in parenthesis? followed [20]? normally passing a pointer you would do 12345 void foo...
Initialization of Pointer Arrays in C - A pointer is a variable that stores the address of another variable. The name of the pointer variable must be prefixed by the * symbol. Just as in the case of a normal variable, we can also declare an array of poin
