| | Hi, There is short explanation of queue at cplusplus.com site which tells that queue should contain front() and back() functions. As I have tested in VC++, if I use queue from <queue> and call any of these functions for an empty queue, program crashes. Could this problem be solved by … |

| | Hi, I've been searching around about DLLs and I can't get what they actually are. Why do we need .cpp, .h and .dll file and how do we link it using CodeBlocks? I used tutorials to create DLL files, and it was successful, they contained 2 functions, but linking is …  |

| | Hi, When writing a little code for showing ASCII characters in C++ and C, the only difference is when I do it in C++ I print until char ( or integer ) reaches value of 127, and in C I print until it reaches 255. Why it's like that? Thanks! |
