I'm trying to have a list of cheeses that you can search through to get to a certain one. When I am done I also want to add info about each one. But every time I run my code I get the error shown in the title. Here is my code:

```
#include<stdio.h>
#include<string.h>

int main()
   {    
    char cheeses[][20] = {
        "Cheddar",
        "White Cheddar",
        "Colby Jack",
        "Gouda",
        "Blue Cheese",
        "Gorgonzola",
        "Asiago", 
        "Limburger",
        "Feta",
        "Brie",
     };

         void find_cheese(char search_for)
     {
         int i;
         for (i = 0; i < 5; i++) {
             if (strstr(cheeses[i], search_for))
                 printf("Cheese %i: '%s'\n", i, cheeses[i]);
          }
    }

int main()
    {
        char search_for[20];
        printf("Search for: ");
        fgets(search_for, 20, stdin);
        find_cheese(search_for);
        return 0;
     }
}

```

Why is this happening? I've looked it up in my book, but can't seem to find the answer.
