c#读取整数空格

Prerequisite: new and delete operator in C++

先决条件： C ++中的new和delete运算符

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

在这里，我们将学习如何声明，读取和打印动态分配的数组？

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

动态数组由new运算符声明，由delete运算符删除 。

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

在这里，我们将读取元素总数，读取元素总数并进行打印。

Consider the following program:

考虑以下程序：

#include <iostream>
using namespace std;
int main()
{
int *arr;	
int i,n;
cout<<"Enter total number of elements:";
cin>>n;
//declare memory
arr=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;	
}

输出量 (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
