C++ Program to Implement Variable Length Array
Variable length arrays can have a size as required by the user i.e they can have a variable size.
A program to implement variable length arrays in C++ is given as follows −
Example
Live Demo
#include <iostream>
#include <string>
using namespace std;
int main() {
int *array, size;
cout<<"Enter size of array: "<<endl;
cin>>size;
array = new int [size];
cout<<"Enter array elements: "<<endl;
for (int i = 0; i < size; i++)
cin>>array[i];
cout<<"The array elements are: ";
for(int i = 0; i < size; i++)
cout<<array[i]<<" ";
cout<<endl;
delete []array;
return 0;
}The output of the above program is as follows −
Enter size of array: 10
Enter array elements: 11 54 7 87 90 2 56 12 36 80
The array elements are: 11 54 7 87 90 2 56 12 36 80
In the above program, first the array is initialized. Then the array size and array elements are requested from the user. This is given below −
cout<<"Enter size of array: "<<endl;
cin>>size;
array = new int [size];
cout<<"Enter array elements: "<<endl;
for (int i = 0; i < size; i++)
cin>>array[i];
Finally, the array elements are displayed and the array is deleted. This is given below −
cout<<"The array elements are: ";
for(int i = 0; i < size; i++)
cout<<array[i]<<" ";
cout<<endl;
delete []array;
