... a dedicated SAPI function). Speed: echo x vs print x Unlike echo, print allocates a temporary variable. However, the amount of time spent on this activity is minuscule, so the difference between these two language constructs is negligible. Speed: echo a,b,c vs echo a.b.c The first one compiles...

...e or SOS (son-of-strike) shows you how objects are laid out. Or you could allocate two objects and then use unverifiable operations to subtract the addresses. 99.9% of the time, the two objects will be adjacent. You can also use a managed profiler to get a sense of how much memory is consumed by i...

...of which is handling ownership of an object. When an object is dynamically allocated with new, it must be deallocated with delete (or the [] versions thereof). The object or function that is responsible for the destruction of the object is considered the owner of the resource. When a dynamically all...

We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and...
