**Q5)** Write a program in C++ to input two decimal numbers and check if the ceil value of their remainder is even or odd.

#### Program

```
#include <iostream>
#include <conio.h>
#include <cmath>
using namespace std;
int main()
{
float a,b,r;
int x;
cout<<"Enter 2 decimal numbers\n";
cin>>a>>b;
r=fmod(a,b);
x=ceil(r);
if(x%2==0)
{
cout<<"Even Number";
}
else
{
cout<<"Odd Number";
}
return 0;
}
```

#### Output

Enter 2 decimal numbers 11.31 7.24 Odd Number
