C++ Error: Invalid conversion from ‘char’ to ‘const char*’
compWord[x] gets char and you are trying to assign it to string, that’s wrong. However, your code should be something like

glibc detected : double free or corruption
That’s because of this line : key+=sizeof(key); . key doen’t contain the same address as the malloc returned address. For example: char *key =(char*)malloc(sizeof(char) * 25); Let’s say malloc returns the address 20000 (totally dumb address, it’s just for the example). Now you’re doing key+=sizeof(key);, so key = 20000 + 4 = 20004. The problem … Read more

If I have something like std::vector what happens when the vector destructor is called? Would it call automatically the destructor of myClass? Or only the vector is destroyed but all the Objects it contains are still existant … Read more
ASCII art in C++
The escape sequences are interpreted as single special or other characters, hence the strange output. “\\” means ‘\’ for example. You can use a raw string literal: live demo
Why is this vector iterator not incrementable?
erase invalidates the iterator. You can’t use it any more. Luckily for you, it returns an iterator that you can use: Or: Are you responsible for freeing the memory referred to by the pointers in the vector? If that’s the reason that you’re iterating (and your real program has more code that you haven’t shown, … Read more
