User-added image
Appilcation:
<aura:application extends="force:slds" >
    <c:additioncomponent/>
</aura:application>
​​​​​​​
component:
<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    
<lightning:input label="enter val1" aura:id="value1" type="number"/>
    <lightning:input label="enter val2" aura:id="value2" type="number"/>
    <lightning:input label="result" aura:id="res" type="number"/>
    <lightning:button label="add" onclick="{!c.show}"/>  
</aura:component>

Controller:
({
    show :function(component, event, helper) {
        var val1=component.find("value1").get("v.value");
        alert("val1::"+val1);
        var val2=component.find("value2").get("v.value");
        alert("val1::"+val1);
        var result=parseInt(val1)+parseInt(val2);
        alert("result::"+result);
        var val1=component.find("res").set("v.res",result);
    }

Hi Srikanth,

The issue is the below line (Line No: 9):  
var val1=component.find("res").set("v.res",result);  --->   var val1=component.find("res").set("v.value",result);

set("v.value")  not set("v.res") 
({
    show :function(component, event, helper) {
        var val1=component.find("value1").get("v.value");
        alert("val1::"+val1);
        var val2=component.find("value2").get("v.value");
        alert("val1::"+val1);
        var result=parseInt(val1)+parseInt(val2);
        alert("result::"+result);
        var val1=component.find("res").set("v.value",result);
    }
})

Thanks,

one small change :

No need of assign the result in val1. 
({
    show :function(component, event, helper) {
        var val1=component.find("value1").get("v.value");
        alert("val1::"+val1);
        var val2=component.find("value2").get("v.value");
        alert("val1::"+val1);
        var result=parseInt(val1)+parseInt(val2);
        alert("result::"+result);
        component.find("res").set("v.value",result);
    }
})

Thanks,
