Question

I am creating a basic C++ code for my first school assignment that simply requires me to create a program that asks for a time in hours, minutes and seconds and converts how much time this is equivalent to in seconds; extremely basic.

I think the errors I am getting are because of my possible misuse of the struct function.

After getting the same error: “expected primary-expression before â.â token” after multiple trials of tweaks, I decided to try the code without struct; simply defining them with float h,m,s,et and calling them by that name: cin >> h >> m >> s;. And it works. This is why I think the error is with my use of the struct function.

Here is the short code:

#include <iostream>

using namespace std;

int main() {

struct time {
 int hour;
 int minute;
 int second;
 int elapsedTime;
};

cout << "Enter a Time in the Format: HH MM SS: ";

cin >> time.hour >> time.minute >> time.second;

time.elapsedTime = ((time.hour*360)+(time.minute*60)+time.second);

cout << "The Amount of Time Elasped is: " << time.elapsedTime << " seconds." << endl;

return 0;

}

The aforementioned error is in the code’s 16th line 3 times and once in it’s 20th line.

Another error in the 18th line is: “expected unqualified-id before â.â token”.

Any help would be greatly appreciated. I refuse to look at the professor’s posted answers yet.

Thank you for your time 🙂

With:

struct time {
 int hour;
 int minute;
 int second;
 int elapsedTime;
};

you just declared the structure of your struct. You have to instantiate an instance of it:

time mytime;
cin >> mytime.hour;
cin >> mytime.minute;
cin >> mytime.second;
