Control of formatted output#include int main (void) {float a=111123.681111f;printf ("%1.3f", a);return 0;}Results: 111123.680So 1.3 is only for the fractional part.Format input#include int main (void) {int a=0;scanf ("%8d\n", &a);printf ("%1d\n", a);

Summarize the common sorting algorithm in C, although most languages already provide sorting algorithms, such as the C function library provides the qsort sorting function (internal for the fast sort implementation), but understanding the idea of

In C + + more powerful than in C!#define定义常量, just simple text substitution, do not do type detection, error prone.const int a = 10;1 //defining a Const constant is the type int by default, and the const-defined symbolic constant has its own data

In fact, C also has the concept of this name spaceIt is useful to prevent naming conflicts, especially in large programs, to save energy and avoid errors. Can be all introduced, can introduce parts, but also can not be used. Doesn't matter.using

Use of New/delete (C + + only, note that new, delete is not a function but an operator!) Note that the allocation of heap memory is often used when programming with malloc and free in C, and the usual operator is new, and this time it is necessary

Let's start with some gossip.Often non-trained programming enthusiasts, C as an introductory language, often ask: "I learned this xx, what can be done?" ”In fact, with Google, basically anything can be done.You don't even need a list, you can write

Once, the type conversion is how the headache thing, when obtains the UI input, when transforms the database output, transforms the XML to be the object to hit the time ....Today suddenly found that the original is so simple, please look at the code:

Named functions Anonymous methods Lambda expression A delegate is a type that can store a reference as a function, define a delegate, declare a variable of that delegate type, and then initialize the variable to a function reference

Aforge.net is designed for developers and researchers based on the C # Framework, which provides different class libraries and resources for class libraries, as well as many application examples, including computer vision and artificial intelligence,

Dynamic objects are not supported in C # and cannot define a dynamic object like AS3, adding dynamic properties.For example, if you want to pass a series of parameters like AS3, the temporary object will usually usevar o:object = {id: "1", Name:
