Decmial to Binary (answer)

[abdul]

I just thought of putting this code up because some people were asking how to convert a decimal number to 8 bit binary number. So here is a little code:

#include <iostream>
#include <string>
using namespace std;

  ALL ABOVE COPIED FROM TOM's main coding comments:D;)
****************************************************************/


//Function to convert decmial number to its binary form 
string dectobin(int what)
{
    
    char bin[10] = "";
    int dvs = 128;

    while (dvs>=1)
    {
        if (what >= dvs)
        {
            what = what - dvs;
            strcat(bin,"1");
        }
        else
        {
            strcat(bin,"0");
        }
        dvs = dvs/2;
    }
    return bin;
}

//An example of using the above function
int main() 
{
    int x;
    cout<<dectobin(195)<<endl;
    cin>>x;
    return 0;
} 

Like the title comments?

to speed it up, replace
dvs = dvs / 2; // shorter would be dvs /= 2;
with
dvs >>= 1;

The result is the same, yet bitshifting is faster than divisions.
