float iarray[n];
float dable;
cout<<"enter values for your array"<<endl;
for(int i=0;i<1;i++)
{
cout<<"for element:"<<i<<endl;
cin>>iarray[i];
dable=iarray[i*2];
}
cout<<"these are the value in your array"<<endl;
for(int i=0;i<n;i++)
{
cout<<dable<<" ";

# include <iostream>
# include <limits.h>// For INT_MAX
using namespace std;

int main()
{
    const int n=7;
    float iarray[n];

    cout << "Enter values for your array " << endl;

    for(int i=0;i<n;i++)
    {
        cout << "For element:" << i << endl;
        cin >> iarray[i];
    }

    cout << endl << "These are the value in your array" << endl;
    for(int i=0;i<n;i++)
        cout << iarray[i] << " ";

    cout << endl;

    cin.ignore(INT_MAX,'\n');

    return 0;
}

how can you put 2 and your program between 0 to 1 !!

for(int i=0;i<1;i++)
{
cout<<"for element:"<<i<<endl;
cin>>iarray[i];
dable=iarray[i*2];
}
