Question on pointers as return functions.
- Hey, regarding a question on returning pointers as functions, why does my code produce this error & won't print out the sum = 6?
- 
- 
`#include<stdio.h>- #include<stdlib.h>
- int *Add(int *a, int *b){
int c = (*a) + (*b);- return &c;
- }
- int main (){
int x=2, y=4;int *Ptr = Add(&x,&y);printf("Sum = %d",*Ptr);}`Also, how do you even format the above to become a code in Codidact? X'D
