Hello, I am getting up to speed with C during the week and I have written one of my first programs and I do not understand why the return of the function. If I input X as 3, Y as 4 and N as 6 I get the return as several million. I should be getting the return of check funtion as 1 with those inputs.

#include <stdio.h>

int check(int x,int y,int n);

int main(void)
{
int x,y,n;
printf("\nValue of X: ");
scanf("%d", &x);

printf("\nValue of Y: ");
scanf("%d", &y);

printf("\nValue of N: ");
scanf("%d", &n);

check(x,y,n);
printf("check = %d", check);
if (check == 1){
printf("\vx and y checked out.");
}
else if (check == 0){
printf("Digits failed the check");
}
}

int check(int x,int y,int n)
{
int i=0;
if (x>0 && x<(n-1)){
if (y>0 && y<(n-1)){
return 1;
}
}

}
