Help for c++ vexcode iq

i need some help learning where each line of code goes in, in the text project in vexcode iq. can someone explain it to me? thanks!

could you maybe post the code?

actually, nevermind
the knowledge base helped me(https://kb.vex.com/hc/en-us/articles/360047058191-Starting-Downloading-and-Running-a-VEXcode-IQ-C-Project)
but what does the ‘build’ button do?

tells you your errors if you have any

ok, thank you, @UvuvwevweOnyetenye!
