C How To Declare Triple Pointers In Array Of Pointers Stack Overflow How to declare a triple pointer with array of pointers like i have char *mainmenu [] = {"menu1", "menu2", "menu3"} see the picture how to connect my menu1,2,3 with those from the picture m1p1 m2p1. The function can simply allocate memory with malloc or calloc and store the result, at the end write the pointer to the result to the pointer given by the argument by dereferencing it, like *argument ptr = result pointer.

C Char Array Of Pointers Stack Overflow I am currently attempting to create a triple pointer to point to and update the contents of a statically allocated 3d array in c. the updating of the elements of the array will be completed by a function like:. If you pass a triple pointer, you would be able to allocate and assign a double pointer, and so on. since 2d array is a double pointer, assigning it requires a triple pointer. This question goes out to the c gurus out there: in c, it is possible to declare a pointer as follows: char (* p)[10]; which basically states that this pointer points to an array of 10 chars. I know this question has been asked a lot, but i'm still unclear how to access the structs. i want to make a global pointer to an array of structs: typdef struct test { int obj1; int obj2.

Start at the variable, then go right, and left, and right and so on. int* arr1[8]; arr1 is an array of 8 pointers to integers. int (*arr2)[8]; arr2 is a pointer (the parenthesis block the right left) to an array of 8 integers. int *(arr3[8]); arr3 is an array of 8 pointers to integers. this should help you out with complex declarations. I'm searching for an example or explanation why someone should (or should not) use triple pointers in c c . are there any examples where triple pointer arise? i am especially looking for source code which uses triple pointers. You usually should assign the result of malloc to some direct pointer (e.g. to indiids not (*indiids) in your case). compile with all warnings & debug info (e.g. gcc wall g on linux). An array of pointers is written as a pointer of pointers: student **db = new student*[5]; now the problem is, that you only have reserved memory for the five pointers. so you have to iterate through them to create the student objects themselves. in c , for most use cases life is easier with a std::vector. std::vector db; now you can use push back () to add new pointers to it and.
