Telephone bill

[SteadyEddie]

I have to write a program to calculate a telephone bill, which converts hours into minutes (done), show the day of the week in full from a single letter input (done) calculate the cost of the call (this is were I am stuck). The first 3 minutes are charged at 1.50 and any minutes after that are charged at 0.30 per min.
The calculation that I have tried reads as follows:

 //This Section Calculates The Cost Of The Call. 
void CallCost()
{
    if (CallLength<=3)
    {
        sc=1.50;
 
        cout<<"The COST Of This Call Is."<<sc<<endl;
    }
 
    else
    {
        (CallLength>=4);
        CalcCall=(CallLength-3)*0.30+1.50;
        cin>>CalcCall;
        cout<<"The COST Of Your Call Before Being Discounted Is "<<CalcCall<<endl;
 
    }
}
 

sc is short fo Standard Charge.
When I input a call lasting 3 minutes I get the answer 1.50, and when I enter a call for 5 minutes I get the same answer instead of 2.10. It is probably something stupid that I am missing, but it is driving me mad.
Any ideas.

Right here's a posting tip to start with, if you enclose your posted code in [code] and [/code] then you white space will be preserved making it easier to read.

Onto your code, did you copy/paste it from your program or re-type it? It is advisable to copy/paste as this cuts out the possibility of retyping errors. The code you have typed does not look like it can have the behaviour you describe but here is my assesment

1| {
2|     (CallLength>=4);
3|     CalcCall=(CallLength-3)*0.30+1.50;
4|     cin>>CalcCall;
5|     cout<<"The COST Of Your Call Before Being Discounted Is "<<CalcCall<<endl;
6| }

Line 2: This has no effect at all and can be removed
Line 3: Makes the correct calculation but ...
Line 4: Overwrites this with some value input by the user
