Declare a pointer in declaration and then use it. e.g #include<iostream> using namespace std; int main() { int len1,*arr1; cout<<"please enter the length of arrayn 1"; cin>>len1; cout<<"creating array now"; arr1= new int[len1]; cout<<"please enter the elements now"; for(int i=0;i<len1;i++) { cin>>arr1[i]; cout<<endl; } return 0; cout<<arr1; delete [] arr1; …
The End.
