#include <stdio.h>

int main(void) {
int x;
float y,z,a;
scanf("%d %f",&x,&y);
a = (float)x;

if((x%5!=0) || (a>y)){
    printf("%.2f",y);
}
if(x>2000 || x<=0 || y>2000 || y<0){
    printf("%.2f",y);
}

if((x%5==0) && (y>a+0.50)){
    z = y - a - 0.50;
    printf("%.2f",z);
}
return 0;

}

What’s wrong in this code?Please reply.

Can someone tell me whats wrong with this code:
x,y=input().split()
w=float(x)
b=float(y)
if w<b and w%5==0:
r=b-w-0.5
print®
else:
print(b)

#include <stdio.h>

int main(void) {
int wid;
float tot;
scanf("%d",&wid);
scanf("%f",&tot);
if((wid+0.50)<tot)
{
if(wid%5==0)
printf("\n%.2f",(tot-wid-0.50));
}
else
printf("\n%.2f",tot);
// your code goes here
return 0;
}

What is wrong in this code?

//WHAT IS WRONG IN THIS CODE???

First thing …(using namespace std; ) will solve the iostream inclusion issue.
second fault in code is at certain test case …cout or remaining balance is negative .For eg 120 120.4 wil give -0.5 which is wrong . So add one more condition in if statement ie ( withdrawl +0.5)<=currentBalance
third just a suggestion,avoid using x and y, give useful names

#Beginner : ATM
fee = 0.50
amount, total = map(float,input().split())
if amount%5==0 and amount<total+0.50:
print(’%.2f’%(total-amount-fee))
elif amount > total:
print(’%.2f’%total)
elif amount%5 != 0:
print(’%.2f’%total)

It is running perfectly with custom inputs but after submitting it is stated as Wrong answer. Please help me to figure out the issue.

do else instead of writing all conditons

121

the input is 120 120.00 and my output is 120.00 but my submission is wrong why?
here is my code:
#include<stdio.h>
#include

using namespace std;
int main()
{
float y,z,w;
int x;
scanf("%d%f",&x,&y);
if(y<=0 || y>2000.00){
cout<<“0.00\n”;
}
else if(x>0 && x%5==0 && x<y){
w =(x+0.50);
z =y-w;
printf("%.2f\n",z);
}
else{
printf("%.2f\n",y);
}

return 0;

}

122

what is wrong in my code?

#include<stdio.h>
#include

using namespace std;
int main()
{
float y,z,w;
int x;
scanf("%d%f",&x,&y);
if(y<=0 || y>2000.00){
cout<<“0.00\n”;
}
else if(x>0 && x%5==0 && x<y){
w =(x+0.50);
z =y-w;
printf("%.2f\n",z);
}
else{
printf("%.2f\n",y);
}

return 0;

}

123

Double declaration of k

Float amt not atm

125

def atm(num1, num2):
y = int(num1)
z = float(num2)
lastdig = int(repr(y)[-1])
if y>z or y==z:
return(format(z, ‘.2f’))
else:
if lastdig == 0 or lastdig==5:
m = float(z-y-0.50)
return(format(m, ‘.2f’))

    elif lastdig != 0 or lastdig != 5:
        return(format(z, '.2f'))

moneydraw, moneyin = input("").split()
print(atm(moneydraw, moneyin))

I wrote this Python code and when I submit it, it states that it is wrong but whenever I run it on my computer or on the codechef IDLE it works very well

126

#include <stdio.h>

int main(void) {
int x;
float a;
scanf("%d",&x);
scanf("%f",&a);
if(x>0 && x<=2000)
{ if(x%5==0 && x<=a)
{
a=a-x-.5;
printf("%.2f",a);
}
else if (x%5!=0 || (x+0.5)>a)
printf("%.2f",a);
}
return 0;
}
what is wrong with my code?

127

there would be -0.5 not +0.5

128

#include<stdio.h>
int main(){
unsigned int x;
float y;
scanf("%d",&x);
scanf("%f",&y);
if(0<=x<=2000&&0<=y<=2000){
if(x<=y&&x%5==0){
y=(y-x)-0.5;
printf("%.2f",y);
}
else
printf("%.2f",y);
}
return 0;
}

but it shows wrong ans??

129

use bufferedreader instead of scanner

130

yes

131

That was asked 5 years ago

cook your dish he

amount=0
balance=0
inp=’’
try:
inp=input()
if len(inp)!=0 and len(inp.strip())!=0:
amount, balance = inp.split(" “)
except Exception as e:
pass
amount = int(amount)
balance = int(balance)
if 0<=amount<=2000 and 0<=balance<=2000:
print(amount,end=” “)
print(balance)
if amount%5==0 and amount+0.5<balance:
balance=balance-amount
balance=balance-0.5
else:
balance=0
print(”{:.2f}".format(balance))

why i’m getting wrong answer when i submit,i tested all possible cases and fixed errors
