'=' function as left operand Errors?

[StrugglingStudent]

I'm having problems finishing my program, it keeps giving me the error '=':function as left operand. And im not sure what that means. It is supposed to be a function to calculate basic car rental prices. This piece of the program is where it is telling me its wrong. Im not sure how to fix it though. Any help would be excellent.

switch(car_type) 
    { 
        case 1: 
            cost=29.90;
            extra=0.29;
            total=total(cost,days_rented,km_traveled,extra); 
        break; 
        case 2: 
            cost=39.95;
            extra=0.39;
            total=total(cost,days_rented,km_traveled,extra); 
        break;
        case 3: 
            cost=49.95;
            extra=0.49;
            total=total(cost,days_rented,km_traveled,extra); 
        break; 
        case 4: 
            cost=59.95;
            extra=0.59;
            total=total(cost,days_rented,km_traveled,extra); 
        break; 
    }

In your switch cases , you are assigning the function return values in variable . this is actually function name ( total) . Which means that you are having the same name for function and your variable (total) . That is why it is throwing the error. Change your variable name or change your function name . It will work fine.

Thank You so much! That makes so much more sense!

Agreed. You probably want to remove that line from each of the statements, and put after the switch

            return total(cost,days_rented,km_traveled,extra);  
 

This assumes your current function is something like
double total (int car_type, int days_rented, int km_traveled)
and you have another function like:
double total(double cost,int days_rented,int km_traveled,double extra)


edit- ah well too late.
