Greetings to you!
You need to use action.setCallback, getState, getReturnValue instead of action.setcallback, getstate, getreturnvalue
As lightning is based on aura framework which is a type of JavaScript and JavaScript is case sensitive so lightning is case sensitive.
Use below code:
({ doInit : function(component, event, helper) { var action = component.get("c.fetchuser"); console.log("vachindhi"); action.setCallback(this,function(response){ var state = response.getState(); console.log(""+state); if(state==="SUCCESS"){ var storeresponse=response.getReturnValue(); component.set("v.usercmp",storeresponse); } }); $A.enqueueAction(action); } })I hope it helps you.
Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future. It will help to keep this community clean.

Javascript is case-sensitive.
action.setcallback is not a function because setCallBack should be:
action.setCallback
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
