can anyone tell why this is wrong??

whats wrong in this?

what is wrong in this?
its giving perfect output in my system

Its giving wrong answer while submitting, can any one help…
its giving perfect output on my system


#10

#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)

else
{
printf(”%.2lf

}
}

	else
	{
		printf("%.2lf

It’s giving me wrong answer, but it works perfectly on my system giving me the correct output.

tell me what is wrong in it.


#14

Can somebody please explain what’s wrong with the following code? It is running fine in my machine and I am getting runtime error here.

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;
System.out.print(n);

 }

}


#15

#include
using namespace std;
int main()
{
int with;
float bal ,c;
c = ((bal-with) -0.50);
cin>>with>>bal;
if (with > 0 && with <=2000 && bal >= 0 && bal <= 2000)
{ 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.


#17

@anianand92
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.

cout<<setprecision(2)<<f;
}
else
{
cout<<fixed;
cout<<setprecision(2)<<(y);

return 0;

 return (0);

}

/* whats wrong in this???


#20

@prerak13
if (x<y && x%5==0)
y=y-x-0.5;—>wrong

if(x-0.5<=y and x%5==0) then only the withdrawl can be made.
