Help! Warning: Initialization makes integer from pointer without a cast

I am writing a program and in line 50 it marks me this: Warning: Initialization makes integer from pointer without a cast. How do I fix it? The problem started when I had to create a loop to ask whether yes or no if the user would like to calculate another trip. I do not know how to fix. Please help.

Code:

---

#include <stdio.h>

int main(void)

{
 
  float numP, numL, HalfCost, EachLcost, TotalHalf, TotalCost, ans;
  int loop; 

  printf("\nPlease enter the number of passengers. Children under the age 12 are represented by .5: ");
 
  scanf("%f",&numP);

  if (numP<0 )
        numP=3;
  else
        printf ("%f",numP);
 
  printf ("\nHow many legs the trip has to get to the destination?");
  scanf("%f",&numL);
  TotalHalf = 0;

  loop=1;
  while (loop <= numL){

      printf("\nWhat is the price of leg %d?",loop);
      scanf("%f",&EachLcost);
      TotalHalf =TotalHalf + EachLcost;
      loop++;
}
  printf("\nThe total cost for half the trip is:");

  if(TotalHalf>0)
        printf("%f",TotalHalf);
 
     
  TotalCost=TotalHalf*2;
  printf("\nThe round trip cost for one person is: $ %f",TotalCost);
 
  printf("\nThe round trip cost for %f persons is: $ %f",numP, TotalCost*numP);


  // return TotalCost*numP;
   
  printf("\nWould you like to calculate another trip cost? (Y/N)?");
  scanf("%c",&ans);
 
  if(ans == 'Y')
    return main;

  else(ans== 'N');
    printf("\nThank You!");

  return TotalCost*numP; 
}

change ans to a char (it's a float now).

Right after the scanf("%c", &answ);

add this:

getchar();

to remove the newline char that scanf() leaves behind on the keyboard stream.

Code:

---

if(ans == 'Y')
return main;

---

is bad code - make it a loop, also (nested, with the one you have now).

Hey, calling main.... always a good way to blow up the stack...

> return main;
This is a function pointer
What you're doing is returning the address of main, not calling main.
And since this is a pointer, and main expects to return an int, this is why you're getting a "integer from pointer" error message.

return main();
Now this would call main recursively, and as noted would be a bad thing to do.

If you want a loop, do this

Code:

---

do {
  // your code you want to repeat
} while ( ans == 'y' );

Thank you all very much for all your help.
