You don’t generally handle the animations themselves directly in code, you should probably be looking into Animation Blueprints, Blendspaces and montages for much better control of how they behave in relation to eachother, the environment, directions, timings etc. then you can apply that to your character, with code if you want.
If you absolutely want to just hardcode an animation to play, you can use this:

Thanks for the message. Got it will try 
You could also try the control-rig inside unreal: Control Rig | Unreal Engine Documentation
Ultimately, animations are the movement vectors for each bone over time, frames, etc. The apps that handle animation keep track of all the bone-constraints, the parent-child relationship, root-motion etc; if you did that in C you would need to keep track of an inordinate amount of housekeeping.
As well, I might suggest the freebies Epic has available, and the animations from all the Paragon characters (they can be re-targeted to different skeletons).
Animation overall is kind of it’s own thing in that you don’t directly program it but make it in some other external module/content-creator.
Greetings,
Thanks for reply :), and the suggestion
