"Like" means (ahdictionary) "To find pleasant or attractive; enjoy." It can be strong or weak.
In English, for better or for worse, we have a single word, "love," which encompasses all three of these feelings. You have to know which is meant from context.
a) The feeling I have for food, music, weather. It is the same feeling as "like," but stronger. I like yogurt, I love ice cream. I like jazz, I love classical music. I like spring, but I really love long lazy summer days.
b) The feeling I have for good friends, grandchildren, our dog. I love them.
c) Erotic or sexual feelings.
