I am wondering,How to write a function in c that return int pointer for any string input

The below function is my attempt to solve the requirment

int* methodname(char* param)
{
  int *a;
  int b=3;
  a=&b;
  return a; 
}

Please correct me for any mistakes.

Returning local address is undefined, refer below code.

int* methodname(char* param)
{
  int *p = malloc(5*sizeof(int));
  . . .
  return p; 
}

Your declaration is ok but definition makes no sense, if any interviewer asked such kind of question their main intention is to check your programming skills, but your definition will not impress him, just write rough body(mainly concentrate on syntax, how you are returning and no undefined behavior) instead of implementing useless code.
