//Driver program for taking input(element) for an array. int main(){ int size = 5; int arr[size]; for (int i = 0; i < size; i++) { cout << "Enter array element: "; cin >>arr[i]; } cout << "The array elements are:"; for (int i = 0; i < size; i++) { cout << arr[i] << " "; } return 0; }

int main() { int arr[5]{}; for(int i=0;i<5;i++){ cin>>arr[i]; cout<<arr[i]<<' '; } cout<<'\n'<<arr[3]<<'\n'; }

You can use a loop and take input in every single variable of the array. If you use a loop, your program time complexity is O(n) . You need to continue your loop size time of that array. In C++ vectors is more useful than arrays.
