in this code i have used pointer variable temp in every function and that variable is being changed in every function . i have a doubt that won’t it lead to memory leak.
Basic pointers doubt
@gulatigarvita08 no it will not. it is defined only in that function.
i hope its cleared if yes dont forget to hit like and mark resolved

but pointer variable can be accessed in any function right?? so how its defined in that function only
no i am talking about temp var that you are defining inside right thats why . its scope is inside only
Pointers are similar to normal variables in that you don’t need to delete them. They are removed from memory at the end of a functions execution and/or the end of the program
