Templates are-----to make the code more generic, so that the code is not affected by the data type. Reduce code redundancy. The template passes the data type as a parameter. Includes function templates and class template.Function templates://define

The simplest lambda:int Main () { = []{}; Lambda ();}To make lambda more useful, you need to capture local variables.#include int main () { int1; = [x] { printf ("x=%d", x); }; Lambda ();}[x] is a value-based snap,

Basic data types for C languagesWhen we play games, the characters in the game are type, agile, power, spell, and so on. The same is true for the C language, where data types can be classified as: basic data types, construction data types, pointer

predicate (predicate): A function that does some detection , returns the type used for conditional judgment , and indicates whether the condition is true or not.Summarize:Count : Counts the number of occurrences of a value in a sequence count_
