what is wrong in this code

[last pilot]

decimal to binary converter

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

int main()
{
int n;
cin >> n;
int ans = 0;
int i = 0;
while (n != 0)
{
int bit = (n & 1);
ans = ans + (bit * pow(10, i)) ;
n = n>>1;
i++;
}

cout << ans;

return 0;

}

if i am using online compiler it is working correctly but if i use vs code then for digit 5 it is giving 100 instead of 101

you are converting decimal to binary but using 10 in the pow bracket. you should use 2.

[last pilot]

nope. If i use 2 then it will convert it back to decimal

[last pilot]

ye kya h?

[lunar galleon]

it was a command to run the code on discord only

I have never faced an issue while using gcc complier but sometimes vscode gives issues, so it might be because of that

[last pilot]

acha

waise i got the answer. i just had to use float data type on ans rather than int

but still i don't know why it was giving error in int

[lunar galleon]

welcome to the world of programming, this happens a lot!

[austere palm]

if it works , no need to touch it

rule 1 of programing

dont fix if not broken

You have to specify the language too

;compile

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

int main()
{
    int n;
    cin >> n;
    int ans = 0;
    int i = 0;
    while (n != 0)
    {
        int bit = (n & 1);
        ans = ans + (bit * pow(10, i)) ;
        n = n>>1;
        i++;
    }

    cout << ans;

    return 0;
}
