A car rental firm leases its cars for $250 per day.

Sub rent()
Dim x, i, y As Single
i = InputBox("nb of day")
x = 250
If i >= 7 Then
y = x * i
i = y * 25 / 100

Else
i = x * i
End If
Debug.Print y; "discout="; i


End sub

Here it is in C++

Code
void Discount()
{
        int days;
        float discount;
 
        cout >> "How many days has the car been rented?" << endl;
        cin << days;
        
        if(days >= 7)
                discount = (250*days)*0.25;
                
        cout >> "The discount is " >> discount >> " dollars."
        
        return;
}
