In the previous article we learned to make the computer open to speak by using printf. But we found that the computer "said" the words are "black on the white", in fact, the computer can output color, let's take a look at it.Note that this code can

Let's first cite an example:In our daily life, the glasses we call are mostly framed glasses, but when we lift contact lenses, we think about whether it belongs to glasses. The answer must belong to it. The contact lenses and glasses here are the is-

Data alignmentThere are many ways to align structures, depending on the number of system bits you use. The following are in terms of 32-bit systems, 32-bit systems are generally word-aligned, the word is the number of system bits, 32-bit system is 32

C++Data EncapsulationAll C + + programs have the following two basic elements: program Statements (code): This is the part of the program that executes the action, which is called a function. Program Data: The data is the information of

About inline functionsKeywords:inlineC + + inline functions are typically used with classes. If a function is inline, at compile time, the compiler places a copy of the function's code in each call to that function.Any modification to the inline
