Can someone tell me why my code worked with printf and not cout and setprecision??

62

X = int(input())
Y = float(input())

if X>0 and X<=2000 and Y>=0 and Y<=2000:
    if X<=Y and X%5==0:
        Y = float(Y - X - 0.50)
        print("%.2f" % Y)
    else:
        print("%.2f" % Y)

I say Runtime error but why?

63

@noswear

input contains only one line,but you are taking 2 lines of input and hence you are getting runtime error.Take single line of input and split them.Then your code will work fine.

Hey i m getting wrong answer. Can pls any1 pls me with this ?

code -

import java.util.*;
import java.util.Scanner;

class Dcoder
{
public static void main(String args[])
{

   double X, Y;
   Scanner scan = new Scanner(System.in);
 
   Y = scan.nextDouble();
   
   X = scan.nextDouble();
   
   X= X+(float)0.50;


   if( X<Y && X%5 == 0){
   	Y = Y-X;
   	System.out.println(Y);
      	}
   else{
   	System.out.println(Y);
   }	 
}

}

my code in java is not working please help me.

import java.util.*;

class sol{

public static void main(String []arg){

Scanner sc=new Scanner(System.in);

float w=sc.nextFloat();

float a=sc.nextFloat();

if(w%5!=0 || w>(a+0.5)){

System.out.printf("%.2f\n",a);

}
else{

System.out.printf("%.2f\n",a-w-0.5);
}
}

}

66

double b,a;
cin>>a>>b;
if((int)a%5 == 0 && a < b && a > 0)
cout<<fixed<<setprecision(2)<<b - a - 0.50<<endl;
else
cout<<fixed<<setprecision(2)<<b<<endl;

please tell me ,what’s the problem ???
i get 4 times WA

what is wrong in this code?It is working fine in my pc but shows run time error during submission

coded this in Python but it is giving me Runtime Error(NZEC). Can you please tell me what is the problem with this?

trans = float(input())

bal= float(input())

if trans%5 == 0 and bal >=(trans+0.50) :
print ( bal - trans -0.50)

else:
print (bal)

if(m>n)

Wrong answer …any1 tell me why …it runs great in my laptop

76

wd_amt,in_amt = list(map(float, input().split()))

this is how you put the input in python

and for output

print("{0:.2f}".format(output))

Can you please tell me what is wrong in below code
