letting user input number of elements in array

can a user input the number of elements in an array? this won't work:

Code:

int liEls;
cout << "Elements in array liaArray[]="; cin >> liEls;
const int cliEls=liEls;
int liaArray[cliEls];

^^note cliEls versus liEls.

i'm trying to learn c++, thanks for your help!

Sure:

Code:

int nArraySize = 0;

cout << "How many items in the array? ";
cin >> nArraySize;

int *pnArray = (int *)calloc(nArraySize, sizeof(int));

// Use pnArray as a normal array...

free(pnArray);

(int *)???
calloc() ???
free() ??

Did you see the sign on the door when you came in? This is a C++ forum.

First lesson: use simple, clear variable names. It appears that picking non-confusing variable names is not your strong suit at this point, so stick with single letters of the alphabet until you get the hang of it.

C++ allows you to dynamically create arrays at runtime. Here is how it is done:

Code:

#include <iostream>
#include <string>
using namespace std;

int main()
{
	int s;
	cout<<"Enter the array size: ";
	cin>>s;

	string* ptr = new string[s];
	
	for(int i = 0; i < s; i++)
	{
		cout<<"Enter some text: ";
		cin>>ptr[i];
	}

	for(int j = 0; j< s; j++)
	{
		cout<<ptr[j]<<endl;
	}

	delete [] ptr;
		
   return 0;
}

-_- I'm just stuck in the past. :P

calloc / free is C, this is C++

So

Code:

int nArraySize = 0;

cout << "How many items in the array? ";
cin >> nArraySize;

int *pnArray = new int[nArraySize];

// Use pnArray as a normal array...

delete [] pnArray;

Did I mention I dislike hungarian notations?

The "best" way to allocate an array based on user input is to use a vector:

Code:

int liEls;
cout << "Elements in array liaArray[]="; cin >> liEls;
std::vector<int> liaArray(liEls);

There is no need to cleanup (delete or free) the memory later, it will be cleaned up automatically like your original static array is.
