The previous period of time work relatively busy, there is no writing essays, and now continue.The first two days re-read the generics and the two chapters, simply say my own harvest　　Generic typeWe know that arrays are a batch of data formats, and generics are actually a custom bulk data format, and when arrays and C # existing generic classes list and dictionaryGeneric classes are strongly type-constrained, meaning that when a generic object is crea

Generic programming, English called Generic programmingCan be understood as, universal meaning, universality, programming.For example, you would implement a function to compare the size of two numeric values, which could be either int or string. For the first attempt, we intuitively think of defining multiple overloaded functions. As follows:int compare (const string V1, const string v2){if (V1 if (V2 return 0;}int compare (const int V1, const int V2)

function templatesRoleThere are many times when the type of the parameter and the type of the return value is variable, and we define the template to make the function more flexible to use.We design a comparison function, if we can compare the two parameters are int, two parameters may be string type, separate design two comparison function will be more cumbersome, at this time, we use the function template.Templateint cmp (t A, T b) {Return a>b;}(1) Each time a call is made, the compiler infers

pointed to by the iterator Gain access to the next object using the increment operator If the new iterator value exceeds the container's element range, a pointer-like value becomes null and the target object is not referenced Classification of iterators Input iterator: Provides read-only access to the object Output iterator: Provides write-only access to an object Forward iterator: Provides forward (incrementing) read and write access to an object Bidirectional

1. About return 0 in the main functionIn the C99 standard, the return value type of the main function must be int so that the return value can be passed to the program's activator (such as the operating system). If the return statement is not written at the end of the main function, C99 specifies that the compiler automatically adds return 0 to the generated target file (such as an EXE file), indicating that the program exits normally. Despite this, someone would add return 0 to the main functio

concurrent programming, the creation and completion of processes is determined by the user. This also occurs with the concept of parent and child processes.Creation of the process:1 #include 2 3 pid_t fork (void); 4 pid_t vfork (voidIn this summary, fork creates a child process that is a copy of the parent process, but uses different data segments and stacks with the parent process. Vfork and fork are basically the same but vfork do not replicat
