Looking for a basic workout routine and ideal diet.? - ideal workout for a 20 year old male

As the title says, I want a very simple program of training and ideal food for weight gain and muscle. I am now 20 years 5'10''y weighs 137 pounds. My plan is to make the army and as you might think I'm probably a little too thin at this time. Can someone me a routine exercise more, based on the resistance and perhaps add more muscle and directed a healthy diet will help to gain weight? It seems that no matter what and how much to eat fatty foods or May, to hold no weight can.

Any help is greatly appreciated, thank you.
