Problems with some old C++ coding ive found.

[Vercingetorix]

Ive found some old C++ project that my son did in his course for college from a few years back, and having previously enjoyed doing programming, i decided to try some of them, i consider myself mediocre at best, anyway one of his later things he was supposed to do was to design a program which should; read in 5 temperatures of the past week put them into an array, by reading the names of the past days into a separate parallel array, find the average of the temperature of the past week and finally and most importantly detect which days the the temperature of the school was below 10 and state them.
This is my code as of now, there seems to be a persistent problem with the line
83 if getline(days, day_temps[loop_counter]);
It keeps showing up as an error. I was hoping that someone could shed a little light on where i'm going wrong with it. Any help would be greatly appreciated.

First, if conditions must be surrounded by parentheses. Second, getline works with a string, not a variable of type double.

[nano511]

Never put a semi colon at the end of the if statement parenthesis.

should just be

if( ... )
{
}

notice there is no semi colon after the )

[Vercingetorix]

OK Ive removed the the semi colon, but still error C2061: syntax error : identifier 'getline'
Comes up and im still completely stumped with what to do.

What is that if there for anyway? It does nothing. Get rid of it.

Let's look at the function getline:
http://www.cplusplus.com/reference/string/getline/

So, it takes two parameters. The first parameter is an istream, and the second parameter is a string.

How are you calling it?
getline(days, day_temps[loop_counter])

What kind of object is day_temps[loop_counter] (which, as you will have noted above, should be a string)?
