Essentially, an operating system’s windowing system exposes some API calls that you can perform to do jobs like create a window, or put a button on the window. Basically, you get a suite of header files and you can call functions in those imported libraries, just like you’d do with stdlib and printf. Each operating system … Read more

On my Python 3.5 install, the error message was a little more useful, and included the URL to get it from Edit: New working link Edit: … Read more
Your header file Hash.h declares “what class hash should look like”, but not its implementation, which is (presumably) in some other source file we’ll call Hash.cpp. By including the header in your main file, the compiler is informed of the description of class Hash when compiling the file, but not how class Hash actually works. When the linker tries to create the entire program, … Read more
Don’t forget to delete every array you allocate with new.

A tab character should advance to the next tab stop. Historically tab stops were every 8th character, although smaller values are in common use today and most editors can be configured. I would expect your output to look like the following: The algorithm is to start a column count at zero, then increment it for … Read more
Segmentation fault is a specific kind of error caused by accessing memory that “does not belong to you.” It’s a helper mechanism that keeps you from corrupting the memory and introducing hard-to-debug memory bugs. Whenever you get a segfault you know you are doing something wrong with memory – accessing a variable that has already … Read more
