Hey Guys! I have a problem with the strcpy function in c++. Here''s the code: struct container { ... char sName[30]; ... }; ... container* inst; inst = new container[0]; strcpy(container[0].sName, "anything"); ... on runtime there''s no problem, but when the programm closes I get uncaught exeptions. The problem occurs also with the sprintf func. It seems like its connected with the sName member of the container struct. If I call none of these string copy funcs, no exeption occurs. here''s the given line: HEAP[Halfcolt.exe]: Heap block at 00B40848 modified at 00B40874 past requested size of 24 help would be great! thank''s in advance

inst = new container[0];

should be

inst = new container[1];

arrays are zero-indexed (the first one''s index is zero), but you still have to creat the proper number when allocating them.

use std::vector and this problem goes away (all of its many facets)
