for beginners question ATM, I am getting wrong answer for this code.

general
1

#include
using namespace std;
int main()
{
int a;
float b,c;
cin>>a;
cin>>c;
if((0<a<2000)&&(0.0<c<2000.0))
{
if ((a<c)&(a%5==0))
{
b=c-a-0.5;
cout<<b;
}
else
{
b=c;
cout<<b;
}
}
return 0;
}

Check your input for-

120 120.00

If it prints -0.5 , i think you get the whats wrong in logic.

3

the output for 120 120.0 is 120, as demanded in the problem, um thats not problem
something else

4

Try this test case then, if 120 120 isnt the failing case then this must be.

Input
119.9 120

Correct output is 120.00

@vijju according to the problem the first number is an integer and second one is a real number. So a better test case would be this :-

Input: 120 120.25

Correct Output: 120.25

Yes you are right. The point was just that, when the values are very close. 120 and 120.1 should also do. Thanks for pointing that out, i will keep it in mind next time :slight_smile:
