Pulling a value from vector every 10 seconds

[tcnjengineer]

So this is my program currently. It not finished but I figured out I would put it up here to see if I could get some help. I used for loops to get the general idea but I really need the program to pull the first value from each array and display the messages and then x amount of time later pull the second value and display those messages until it has pulled all six values from the vector.

I'm printing out the vectors just to see the values while i'm testing the program but eventually i will get rid of that part.

Thank you for the help

I'm a little confused. Where exactly would I put this in my code. Would i only have to do it once or would i have to do it to replace every for loop that i already have in the code.

[JLBorges]

Place it in the loop / loops where you want the delay.

[tcnjengineer]

So I tried to run this code to see how it work and I got multiple errors saying that the i need the 2011 version of c++ and that the compiler that i"m using does not support that. Is there any other way to do it. Or what do i need to do to get it to work with the compiler that im using.

[tcnjengineer]

And i'm also getting runtime error after I run the whole program. It will stop after going through the very first for loop for the temp vector and i'm not sure why it wont run through all of the for loops.

> Or what do i need to do to get it to work with the compiler that im using.

There was no standard C++ way to do that before C++11.

Posix: https://www.freebsd.org/cgi/man.cgi?query=sleep&apropos=0&sektion=3&manpath=FreeBSD+10.2-RELEASE&arch=default&format=html

Windows: https://msdn.microsoft.com/en-us/library/windows/desktop/ms686298(v=vs.85).aspx

[tcnjengineer]

Alright so I updated the compiler and can now do the c++11. But when I try to compile the small program that you sent just to see how it works im still getting errors that im not sure how to fix before i try to change it to work with my program

[tcnjengineer]

I just tried it with just the Sleep function and the delay worked but I need it to pull the first value form each vector after 10 seconds and the the second value from the vector after another 20 seconds
