%matplotlib is a magic function in IPython. I’ll quote the relevant documentation here for you to read for convenience: IPython has a set of predefined ‘magic functions’ that you can call with a command line style syntax.

I guess MERGE_HEAD is only present when a merge is in progress which also is the case when I am resolving conflicts. Correct.

If you mean a C-style array, then you can do something like: This doesn’t work on pointers (i.e. it won’t work for either of the following): or: In C++, if you want this kind of behavior, then you should be using a container class; probably std::vector.

Try this: or better yet: Also, since Int32.TryParse returns a bool you can use its return value to make decisions about the results of the parsing attempt: If you are curious, the difference between Parse and TryParse is best summed up like this: The TryParse method is like the Parse method, except the TryParse method does not throw an exception if the conversion … Read more
Compiling a C++ program takes place in several steps, as specified by 2.2 (credits to Keith Thompson for the reference): The precedence among the syntax rules of translation is specified by the following phases [see footnote]. Physical source file characters are mapped, in an implementation-defined manner, to the basic source character set (introducing new-line characters for end-of-line indicators) … Read more

Use the valgrind option –track-origins=yes to have it track the origin of uninitialized values. This will make it slower and take more memory, but can be very helpful if you need to track down the origin of an uninitialized value. Update: Regarding the point at which the uninitialized value is reported, the valgrind manual states: It is important to … Read more
