C++按值调用
#include <iostream> using namespace std; void swap(int x, int y) { int temp; temp = x; /* save the value of x */
C++默认值参数
#include <iostream> using namespace std; int sum(int a, int b = 20) { int result; result = a + b; return (result);
C++标准输入流
// 标准输入流 #include <iostream> using namespace std; int main() { char name[50]; cout << "Please enter your name: ";
C++标准输出流
// C++标准输出流 #include <iostream> using namespace std; int main() { char str[] = "Hello C++";
C++使用struct格式化时间
#include <iostream> #include <ctime> using namespace std; int main() { // current date/time based on current system
C++当前日期和时间
#include <iostream> #include <ctime> using namespace std; int main() { // current date/time based on current system
C++通过引用返回值
#include <iostream> #include <ctime> using namespace std; double vals[] = {10.1, 12.6, 33.1, 24.1, 50.0};
C++通过引用传递参数
#include <iostream> using namespace std; // function declaration void swap(int& x, int& y);
C++创建引用
#include <iostream> using namespace std; int main () { // declare simple variables inti; double d; // declare reference variables
C++函数返回指针
#include <iostream> #include <ctime> using namespace std; // function to generate and retrun random numbers.
C++函数接受指针参数
#include <iostream> using namespace std; // function declaration: double getAverage(int *arr, int size);
C++传递无符号长整数
#include <iostream> #include <ctime> using namespace std; void getSeconds(unsigned long *par);
C++指向指针的指针
#include <iostream> using namespace std; int main () { intvar; int*ptr; int**pptr; var = 3000; // take the address of var
C++指向字符的数组
#include <iostream> using namespace std; const int MAX = 4; int main () { char *names[MAX] = { "Zara Ali", "Hina Ali", "Nuha Ali", "Sara Ali" };
C++数组最大整数
#include <iostream> using namespace std; const int MAX = 3; int main () { intvar[MAX] = {10, 100, 200};
C++指针数组
#include <iostream> using namespace std; const int MAX = 3; int main () { intvar[MAX] = {10, 100, 200};
