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
#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;
