I made the corrections but 1.why you use float inside if statement and 2. its not showing output for 20

#1

#include
using namespace std;
int main()
{
int n;
float k=1.0,sum=0.0;
cin>>n;
label:
for(float i=0;;i=i+k)
{
if(((sum+i)*(sum+i))>n)
{
i=i-k;
sum=sum+i;
k=k/10;
if(k==((float)0.0001))
{
goto end;
}
else goto label;
}
}
end:
cout<<"\n"<<sum;
return 0;
}

#2

Hey @prerak_semwal
some compilers will take 0.000001 as 0 so to avoid that we typecast it to float
u can alternatively use 0.000001f
Reply here if u dont understand
Please Dont open mupltiple threads for the same doubt

Checking it for 20
