can anyone tell why its wrong . when i use to run my program in my own dev cplus plus compiler its running . but ater submitting it shows wrong answer error
#include<stdio.h>
int main()
{
float y;
int x;
scanf("%d %f",&x,&y);
if(x<y&&(x%5==0))
printf("%.2f",y-x-0.5);

What is wrong with mine code, codechef Judge is giving it wronf Answer??? PLease Help

#include<stdio.h>
int main()

int withdrawl;
scanf("%d",&withdrawl);
scanf("%f",&bal);
if(withdrawl>0&&withdrawl<=2000)
{
if(bal>=0&&bal<=2000)
{
if(withdrawl<bal)
{
if(withdrawl%5 == 0)
{
bal = bal-(withdrawl+0.50);
}
}
}
}
printf("%0.2f",bal);
return 0;
}

this code is working properly in online compiler of codechef .
but its not being accepted in the submit section.

#include<stdio.h>

int main()
{
   int X;
   float Y;
   scanf("%d %f",&X,&Y);
   if(Y<2000)
   if((X%5==0)&&(X<Y))
    Y=Y-X-.5;
   printf("%.2f",Y);
   
   return 0;
}

it gets all test cases but shows ‘Wrong answer’

34

#include<stdio.h>
int main()
{
int x;
float y , z;
scanf("%d",&x);
scanf("%f",&y);
if(y>=0 && y<=2000);
{
if(x!=0 && x%5==0 && x<y)
printf("%f",y-x-0.50);
}
if(x%5!=0 || x>y )
printf("%f",y);
if(x==0 || x==y)
printf("%f",y);
return 0;
}
what is wrong with the code any one can run it on code blocks and can check it
i have to copy other’s code to proceed further

What is wrong…?

Are you sure that your output is upto 2nd decimal place @anany_097?

because 120.000 is NOT 120.00 and hence would be flagged wrong.
Also, e is the money to be withdrawn. make sure that e is a multiple of 5.

38

Can anyone tell me that why the Codechef mark it as a wrong answer?

    #include <stdio.h>
 
    int main(void) {
	int x; //amount to withdraw
	float y; 	//initial balance
	
	scanf("%d %f",&x,&y);
	if((x>0) && (x<=2000) && (y>=0) && (y<=2000))
	{
		if((x<y) && (x%5 ) == 0)
			printf("%.2f",y-x-0.50);
		else
			printf("%.2f",y);
	}
	
	return 0;
}
39

withdraw**+0.50**>bankamount
This condition is necessary when in input is :
120 120.00
output should be :
120.00
not :
-0.50
