D语言使用元组的元组
import std.stdio; import std.typecons; void main() { auto myTuple = tuple(1, "Tuts"); writeln(myTuple);
D语言将指针传递给函数
import std.stdio; void main () { // an int array with 5 elements. int balance[5] = [1000, 2, 3, 17, 50];
D语言指向数组的指针
import std.stdio; void main () { // an array with 5 elements. double balance[5] = [1000.0, 2.0, 3.4, 17.0, 50.0];
D语言从函数返回指针
import std.stdio; void main () { int *p = getNumber(); for ( int i = 0; i < 10; i++ ) { writeln("*(p + " , i , ") : ",*(p + i));
D语言指向指针的指针
import std.stdio; const int MAX = 3; void main () { int var = 3000; writeln("Value of var :" , var);
D语言递增指针
import std.stdio; const int MAX = 3; void main () { int var[MAX] = [10, 100, 200]; int *ptr = &var[0];
D语言NULL指针
import std.stdio; void main () { int*ptr = null; writeln("The value of ptr is " , ptr) ; }
D语言使用指针
import std.stdio; void main () { int var = 20;// actual variable declaration. int *ip;// pointer variable
D语言指针
import std.stdio; void main () { int var1; writeln("Address of var1 variable: ",&var1); char var2[10];
D语言类模板
import std.stdio; import std.string; class Stack(T) { private: T[] elements; public: void push(T element) {
D语言具有多个类型参数的函数模板
import std.stdio; void print(T1, T2)(T1 value1, T2 value2) { writefln(" %s %s", value1, value2);
D语言函数模板
import std.stdio; void print(T)(T value) { writefln("%s", value); } void main() { print(42);
D语言混入名称空间
import std.stdio; template Person() { string name; void print() { writeln(name); } } void main() { string name;
D语言模板混入
import std.stdio; template Department(T, size_t count) { T[count] names; void setName(size_t index, T name) {
D语言字符串混入实例
import std.stdio; string print(string s) { return `writeln("` ~ s ~ `");`; } void main() { mixin (print("str1"));
D语言this别名
import std.stdio; struct Rectangle { long length; long breadth; double value() const @property { return cast(double) length * breadth;
