Thread: I want to know is it usually displayed(Error0)or it is my code which may be defected!

Here is my code

Code:

//Program in C
/* Using strchr() & strcmp()
* function(s) to do some conditional(s) */


#include <string.h>
#include <stdio.h>
#include <conio.h>
main() {
clrscr();


char name[20];
char *ptr;
/* Taking an animal name from user */


printf("Hello! Which animal does meow sound? ");
fgets(name, 20, stdin);


if ((ptr = strchr(name, '\n'))) {
    //Replacing newline with NULL
    *ptr = '\0';
}


//Performing check on user input
char match[4] = "Cat";
if (strcmp(name, match) == 0) {
    printf("Bravo! You are correct.");
    getch();
} else {
    perror("Sorry! That was Cat.");
    getch();
}


return(0);


}

Prompt: Hello! Which animal does meow sound?
Input: Doggy
Output: Sorry! That was Cat.: Error 0

Why is Error 0 being displayed?
Please give me explanation.
