[cuthien]

I'm using visual studio, and i'm trying to find my error. i you could please point out what I'm doing wrong, I would appreciate it. Right now I keep getting error error C2064.

char name;
double day, night, regular, premium, totalR;
cout << "Enter your name" << "\nEnter the number of minutes used from 6AM - 6PM" << "Enter the number of minutes used from 6PM - 6AM";
cin >> name >> day >> night;
totalR = day + night;

if (totalR > 50){
regular = 10 + .20((totalR) - 50);
}
else {
regular = 10;
}

if (day > 75) {
if (day > 75 && night > 100) {
premium = 25 + .1(day - 75) + .05(night - 100);
}
else {
premium = 25 + .1(day - 75);
}
}
else {
if (night > 100) {
premium = 25 + .05(night - 100);
}
else {
premium = 25;
}
}

cout << setiosflags(ios ::fixed|ios::sh owpoint) << setprecision(2) ;
cout << "Regular plan cost" << regular << endl;
cout << "Premium plan cost" << premium << endl;

return 0;
}

Just in case it's actually not there, you need

#include <iostream>
#include <iomanip>

using namespace std;

int main() {

at the beginning of your program, but you probably actually have it there and just didn't post it. Your problem is on lines of code like these:

if (day > 75 && night > 100) {
premium = 25 + .1(day - 75) + .05(night - 100);
}
else {
premium = 25 + .1(day - 75);
}

In order to do multiplication in C++, you always have to use the * operator. Parentheses will not do. Your compiler thinks you're trying to call a function. Change these to:

if (day > 75 && night > 100) {
premium = 25 + .1 * (day - 75) + .05 * (night - 100);
}
else {
premium = 25 + .1 * (day - 75);
}

Hope this helps.
