Decimal to binary conversion with c++ programming

Decimal to binary conversion

(only for integer number)

-----------------------------------------------

#include<iostream>

using namespace std;

int main()

{

int no,i=1,a,b[1000],cons;

cout<<"Enter an integer number no.:";

cin>>no;

do

{

a=no/2;

b[i]=no%2;

no=a;

i++;

}

while(no>0);

cons=i-1;

cout<<"Equivalent binary no.:\n";

for(i=cons:i>=1;i--)

{

cout<<b[i];

}

return 0;

}

Output:

Enter an integer no.:30

Equivalent binary no.:

11110
