     In which case do I have to call delete in order to prevent memory leak

     Only delete what you got from new and delete [] what you got from new []. Every other delete is wrong.

     The rules are simple:

     • ["Do not delete "," any pointer for which you did not call new ",""]
     • ["Use delete[] "," for everything that you allocated with new[] ",""]
     • ["Use delete "," (no brackets) for everything that you allocated with new "," (no brackets)"]

     By following these rules you can see that only the deletions of b and e are valid:

     • [" a "," and c "," have not been allocated with a new ",""]
     • [" d "," needs a delete[] ",""]
     • [" b "," and e "," are correct. "]

     They're all wrong. Do not ever call delete in a C++ program (unless you are directly implementing a memory-managing primitive, like smart pointer)- always use a smart pointer to handle resource destruction. For arrays, use a container like std::vector<T>. For strings, there is a dedicated std::string class. Finally, there are no primitive situations except new that create objects suitable for delete, whether directly or correctly (through a smart pointer), so if you did not use new or call a function that explicitly returns such (which should really return a smart pointer...), then you're definitely doing it wrong.

     • Wrong because there's no dynamic memory to delete.
     • ["Wrong because you should use smart pointer ( unique_ptr "," looks fine here)."]
     • Same as 1.
     • ["Wrong because you need std::vector "," for dynamically allocated arrays."]
     • Same as 4.

   • Strings in Structures in C

     You need to allocate memory to copy into:

     myVehicle->name = malloc(strlen(tmpName) + 1); if (myVehicle->name) { strcpy(myVehicle->name, tmpName); }

     as myVehicle->name is an uninitialised char*. If you malloc() you need to free(). The assignment to the string literal works because you making name point to the address of the string literal, which exists for the lifetime of the program.

     But before this, you need to allocate memory for myVehicle itself:

     myVehicle = malloc(sizeof(*myVehicle));-

     or just make myVehicle an object rather than a pointer:

     static vehicle myVehicle;-

   • strings in the subscript in c

     ++a["Gyantonic"]-

     is equivalent to:

     ++(a["Gyantonic"])-

     which is equivalent to

     ++("Gyantonic"[a])-

     equivalent to

     ++("Gyantonic"[1])-

     "Gyantonic"[1] yields 'y' and the ++ increments the 'y' stored in the string literal and yields the result. But "Gyantonic" is a string literal and string literals cannot be modified. This is why you get the segmentation fault.

   • Strings in multidimensional array in C

     Top Answer

     Answered Dec 01, 2013 · 5 votes

     You're defining a 2D array consisting of strings. Since strings themselves are arrays in C/C++, you're essentially creating a 3D array.

     There are multiple ways to fix this:

     • You can use char *board[8][8] to define an 8x8 array of pointers to the strings.
     • You can use char board[8][8][4] to add the missing dimension (this uses the same memory no matter how long single entries are; each entry may have up to 3 characters plus 1 terminator).

     As a side note, you should use the const keyword, as you typically won't want to modify the string contents.

   Strings are used for storing text/characters. For example, "Hello World" is a string of characters. Unlike many other programming languages, C does not have a String type to easily create string variables. Instead, you must use the char type and create an array of characters to make a string in C: char greetings [] = "Hello World!";
