Why aren't pointers initialized with NULL by default?
...Or under other conditions the variable is potentially never used. A lot of C++ developers would scream foul under both conditions at the cost of that extra instruction.
It's not just about time. But also space. There are a lot of environments where both resources are at a premium and the developers...
What is the difference between “long”, “long long”, “long int”, and “long long int” in C++?
I am transitioning from Java to C++ and have some questions about the long data type. In Java, to hold an integer greater than 2 32 , you would simply write long x; . However, in C++, it seems that long is both a data type and a modifier.

In languages like C++ and C#, you can define local readonly fields (within a method body) using them. This is not possible with a conventional if/then statement because the value of a readonly field has to be assigned within that single statem...
When to use dynamic vs. static libraries
When creating a class library in C++, you can choose between dynamic ( .dll , .so ) and static ( .lib , .a ) libraries. What is the difference between them and when is it appropriate to use which?
