C++ program which takes the book parameters and display them using structures

#include<iostream>
using namespace std;
struct bookdetails
{ char name[50];
int page;
char author[50];
string ibn;};
int main()
{ int i=1,j=1,k=1,l=1;
struct bookdetails b1,b2,b3;
while (i<=1)
{ cout<<"enter book names 1-3 ";
i++;
}
cin>>b1.name>>b2.name>>b3.name;

while (j<=1)
{cout<<"no of pages of book 1-3 ";
j++;
}
cin>>b1.page>>b2.page>>b3.page;

while(k<=1)
{cout<<"author name of book 1-3 ";
k++;
}
cin>>b1.author>>b2.author>>b3.author;

while (l<=1)
{ cout<<"IBN of book 1-3 ";
l++;
}
cin>>b1.ibn>>b2.ibn>>b3.ibn;
cout<<endl;
