Not a good approach, but an approach.

great explaination sir.
quetion 4 answer:


#include <iostream>

using namespace std;

int main()
{
int a[5]={1, 2, 3, 4, 5};
int i;
int sd=sizeof(a)/sizeof(a[0]);
cout<<"sd is :"<<sd<<endl;
/// int ele=sd%2==0;
for(i=0;i<sd;i++)
{
if(i%2!=0)
{
cout<<"index of even number"<<a[i]<<endl;
}
}

return 0;
}
