Thank you for continuing to post high quality and easy to follow C lessons. It is not the most popular language but it needs to be made more accessible.

[@xplane7879]

Good to see you back!

so good...

print_val is defined and declared, and can work with defined variables.

[@CodeVault]

It can work with declared global variables too

[@beyreda6029]

Thank you for this very instructive video. By the way, are you sur that multiple declarations are ok in all situations? If I try this with GCC with no external linkage I get an error: redeclaration of ‘a’ with no linkage

[@beyreda6029]

It seems that redeclaration only works with global variables.

[@CodeVault]

Yeah, it's only a feature in GCC that allows you to redeclare multiple global variables

[@glenngodfrey5486]

Tell us now, why you shouldn't use the include directive. Happy New Year.

[@CodeVault]

In a later video I will (probably this week)

[@noweare1]

I always get those two mixed up define vs declare

[@CodeVault]

Trust me, I mixed them up too. Had so many outtakes where I said definition instead of declaration. We should really think of better names for these concepts haha

@@CodeVault function specification => function declaration
function body => function definition
