Editorialist’s solution can be found here.
#include <stdio.h>
main ()
{
int x,y,e;
float z;
printf (“enter the pooja’s account balance “);
scanf (”%d”,&y);
printf (“enter the amount you want to withdraw”);
scanf ("%d",&x);
e=y%5;
if ((0<=x<=2000) && (0<=y<=2000) && (x<y)&& (e=0))
{
z=y-x;
printf (“the current account balance is .2f",z);
}
else if (e!=0)
{
printf (".2f”,(float)y);
}
else if (x>y)
{
printf ("%.2f",(float)y);
}
else
exit (0);
}
Editorialist solution is wrong withdraw%5==0&&balance>=withdraw+0.5 is the correct condition…
You dont need those printf() statements you have added in your code. There’s no need of that, go by the I/O format specified in the problem!!
#include<stdio.h>
int main()
{
unsigned int x; //amount withdrawn
float y; //bank balance
scanf("%d%f", &x,&y);
if(x>0&&x<=2000&&y>0&&y<=2000)
{
if(x>y&&x%5==0)
printf("%0.2f", y);
else if(x%5==0)
{
y=(y-x)-0.5;
printf("%0.2f", y);
}
else
printf("%0.2f", y);
}
getchar();
return 0;
}
Suppose the input is 120 120.00 then your code gives the output -0.50. Check for that case also. Answer for this case should be 120.00
#include<stdio.h>
main()
{
int i;
float k,j;
scanf("%d",&i);
scanf("%f",&j);
if (0<i&&i<=2000 && 0<=j&&j<=2000)
{
if (i%5!=0||i>j)
k=j;
else
k=j-0.50-i;
printf("%.2f",k);
}
return 0;
}
can anyone tell why this is wrong??
#include<stdio.h>
int main(){
unsigned int amt;
float atm=0.5,bal,rlt;
scanf("%u %f",&amt,&bal);
if((bal+atm)>=amt && amt%5==0 && (0<=bal<=2000) && (0<amt<=2000))
rlt=bal-(amt+atm);
printf("\n%.2f",rlt);
return 0;
}
whats wrong in this?
import java.util.Scanner;
/**

class ATM {
public static void main(String[] args) {
float currentBal = 120;
int withdrawAmt;
float charge = (float) 0.50;

withdrawAmt = s.nextInt();
if(withdrawAmt % 5 == 0 && withdrawAmt > 0.00 && withdrawAmt < 2000.00)
{
if(withdrawAmt + 0.5 < currentBal)
{
currentBal = currentBal - withdrawAmt - charge;
System.out.printf("%4.2f\n", currentBal);
}
else
{
System.out.printf("%4.2f\n", currentBal);
}
}
else
{
System.out.printf("%4.2f\n", currentBal);
}
}
}
what is wrong in this?
its giving perfect output in my system
#include<iostream.h>
int main()
{int x,y;
cin>>x;
cin>>y;
if(x>y||x%5!=0)
cout<<y;
else
cout<<y-x-0.5;
return 0;
}
plz tell what’s wrong in this code??why can’t i include iostream.h
import java.text.DecimalFormat;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
DecimalFormat df = new DecimalFormat("#.00");
final double ch=0.50;
int WdAmnt =input.nextInt();
Double PrevBalnc=input.nextDouble();
boolean flag = false;
if(WdAmnt%5 ==0 && WdAmnt<=2000 && PrevBalnc <=2000.00 && WdAmnt>0 && PrevBalnc>=0.00)
flag=true;
else
flag=false;
if(WdAmnt!=0 && WdAmnt<=PrevBalnc && flag)
{
PrevBalnc=PrevBalnc-(WdAmnt+ch);
}
System.out.println( df.format(PrevBalnc));
}
125**What is wrong with this code?**125
#include <stdio.h>
int main() {
int amt;
float bal, a_bal;

printf ("%.2f\n", (bal-amt-a_bal));
else
printf ("%.2f\n", bal);
return 0;
}
Its giving wrong answer while submitting, can any one help…
its giving perfect output on my system
#include <stdio.h>
int main()
{
double total_sum;
int withdraw;
double charges = 0.5;
double withdraw_fin;
scanf("%d %lf", &withdraw, &total_sum);
if(withdraw <= total_sum)
{
if(withdraw % 5 == 0)
{
withdraw_fin = (total_sum - withdraw) - charges;
printf("%.2lf\n", withdraw_fin);
}
else
{
printf("%.2lf\n", total_sum);
}
}
else
{
printf("%.2lf\n",total_sum);
}
return 0;
}
It’s giving me wrong answer, but it works perfectly on my system giving me the correct output.
import java.io.;
import java.util.;
class TEST2{
public static void main(String args[])throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
PrintWriter pw = new PrintWriter(System.out, true);
double initialAmount,widthdrawal;
widthdrawal = Integer.parseInt(br.readLine());
initialAmount = Integer.parseInt(br.readLine());
try{
if(widthdrawal < initialAmount){
if( (widthdrawal%5) == 0 ){
double balance = ((initialAmount - widthdrawal) - 0.50);
pw.println(String.format("%.2f",balance));
}else{
pw.println(String.format("%.2f",initialAmount));
}
}else{
pw.println(String.format("%.2f",initialAmount));
}
}catch(Exception e){
System.exit(0);
}
System.exit(0);
}
}
giving the desired output on my machine…on codechef its showing runtime error NZEC…please help in figuring out whats wrong with the code???
#include<stdio.h>
int main()

printf("%0.2f",remain);
}
else
if((temp!=0)||(x>ini))
{
remain=ini;
printf("%0.2f",remain);
}
return 0;
}
tell me what is wrong in it.
class HelloWorld{
public static void main(String []args){
double i=Double.parseDouble(args[0]);
double j=Double.parseDouble(args[1]);
double n=j-i-0.50;

}
}

{ if((with > bal) || (with 5 != 0))
cout<<bal<<endl;
else if (with 5 == 0)
cout<<c;}
return 0;
}
What am I doing incorrectly?

Whats WRONG in this code…??? please help me.

There is one thing to notice.
Every transaction cost you 0.5 rupees as transaction fees.
So you cannot withdraw money if (x>=y-0.5)
You must have additional 0.5 ruppes in your account.
