When I run this code, I get this error, and I cannot figure it out (please use link about for complete program):

Schedule.cpp:171:1: error: 'vector' does not name a type

171 vector Schedule::getUpcomingEvents() const {

^~~~~~~

To fix this error, you need to include thevectorheader file in yourSchedule.cppfile by adding the following line at the beginning of the file:

#include

This should resolve the error and allow thevectortype to be recognized by the compiler

Explanation:

The error you provided seems to be related to the declaration of theSchedule::getUpcomingEvents()function.

It seems that the compiler is unable to recognize theEventtype. This could be caused by a few different issues, such as:

1. TheEventclass has not been properly declared or defined.
2. TheEventclass is defined in a different namespace or file and has not been properly included.
3. TheEventclass has been declared but not defined, and theScheduleclass is unable to access its members.

To solve this issue, you should ensure that theEventclass has been properly declared and defined and that its header file has been properly included in theScheduleclass. You may also need to check for any issues with namespaces and access modifiers that could be preventing theScheduleclass from accessing theEventclass

So now, when I edit the code to properly declare the vector, this is the error I get:

Schedule.cpp:172:16: error: no declaration matches 'std::vector Schedule::getUpcomingEvents() const' 172 | vector Schedule::getUpcomingEvents() const { | ^~~~~~~~Schedule.cpp:172:16: note: no functions named 'std::vector Schedule::getUpcomingEvents() const' In file included from Schedule.cpp:2:Schedule.h:9:7: note: 'class Schedule' defined here 9 | class Schedule{ | ^~~~~~~~
