To solve this probl...
Why should I avoid multiple inheritance in C++?

How do I use valgrind to find memory leaks?
...first
gcc -o executable -std=c11 -Wall -ggdb3 main.c # add -ggdb3 to it
Now with this debug build, Valgrind points to the exact line of code
allocating the memory that got leaked! (The wording is important: it might not
be exactly where your leak is, but what got leaked. The trace helps you fin...
