float first3 = 2.00;
float addmin = 0.45; float cost;
int minutes;
// Prompt user for minutes talked
cout<<"Enter Number of Minutes: ";
cin>>minutes;
// Calculate cost;
if(minutes < 1)
{
cout<<"Enter a number greater than 0";
}
else if(minutes <= 3)
{
// Calculating cost for minutes less than or equal to 3
cost = connecfee + first3 * minutes;
cout<<"Talk time of "<<minutes<<" minutes costs "<<cost;
}
else
{
cost = connecfee + first3 * 3 + addmin * (minutes - 3);
cout<<"Talk time of "<<minutes<<" minutes costs "<<cost;
}
return 0;
}
// End of Program
