@kailash_01 hi,basically in c++ refernces are used ,generally kya hota haio jab app function me stack pass krrhe ho without reference to function apna nya stack bnata hai aur usme changes krta hai but original stack jo hmne pass kia tha usme koi change nhi hota ,so if we want ki hmare original stack me change ho uske lie hm reference use kia ,just & operator lga do ab jo bhi change honge function ke andr woh original stack s me honge apko kuch return krne ki bhi need nhi.
