c#讀取整數空格

Prerequisite: new and delete operator in C++

先決條件： C ++中的new和delete運算符

Here, we will learn how to declare, read and print dynamically allocated array?

在這里，我們將學習如何聲明，讀取和打印動態分配的數組？

A dynamic array declares by new operator and deletes by delete operator.

動態數組由new運算符聲明，由delete運算符刪除 。

Here we will read total number of elements, read total elements and print them.

在這里，我們將讀取元素總數，讀取元素總數并進行打印。

Consider the following program:

考慮以下程序：

#include <iostream>using namespace std;int main() {int *arr; int i,n;cout<<"Enter total number of elements:";cin>>n;//declare memoryarr=new int(n);cout<<"Input "<<n<<" elements"<<endl;for(i=0;i<n;i++){cout<<"Input element "<<i+1<<": ";cin>>arr[i];}cout<<"Entered elements are: ";for(i=0;i<n;i++){cout<<arr[i]<<" ";}cout<<endl;delete (arr);return 0; }

輸出量 (Output)

Enter total number of elements:5 Input 5 elements Input element 1: 10 Input element 2: 20 Input element 3: 30 Input element 4: 40 Input element 5: 50 Entered elements are: 10 20 30 40 50
