I want to convert decimal to binary but it prints it binary in reverse order without array.

Question

For example
For 8 it prints 0001
But actually it is 1000
****************
#include<iostream>
using namespace std;
int main()
{
int num,i=0;
cin>>num;
while(num>0)
{
i=num%2;
num=num/2;
cout<<i;
}
system("pause");return 0;
}

Answer 2

You can change the order of the numbers by using a for loop and writing every number into an array. Something like this:

arr oldByteArray[8]; //the order here is 0001
arr newByteArray[8];

for(int i = 0; i < sizeof(oldByteArray); i++) {
newByteArray[i] = oldByteArray[8 - i];
}

Answer 3

Yes it prints 0001 coz algo you put is right just print your number in reverse using any loop .

This is my program. I do this like this.
for(i=0; n>0; i++)    
{    
a[i]=n%2;    
n= n/2;  
}       
for(i=i-1 ;i>=0 ;i--)    
{    
cout<<a[i];    
}
