Building on Raindrop7's solution, here's the full code to do what you need:

#include 
#include 
#include 
using namespace std;

int main()
{
    double m;
    cout << "Your input is: "<> m;
    while (cin.fail() || (m-floor(m)))
    {
        cout << "Error. Nubmer of elements has to be integer. Try again: " << endl;
        cin.clear();
        cin.ignore(256, '\n');  
        cin >> m;
    }
    int n = (int)m;
    return 0;
}

Here's a sample output:

Your input is: 
2.7
Error. Nubmer of elements has to be integer. Try again: 
erer
Error. Nubmer of elements has to be integer. Try again:
