To Check Whether a Number is Positive or Negative Using C and Functions

#include <stdio.h>
#include <stdlib.h>

//Definition Of  Functions.
int number1(int x);
int number2(int y);

int main()
{
    int n1,n2;
    printf("Enter Numbers : \n");
    scanf("%d",&n1);
    scanf("%d",&n2);
    number1(n1);//Function Calling..
    number2(n2);//Function Calling..
    return 0;
}
//Function Prototype of First Number..
int number1(int x)
{
    if(x>0)
    {
        printf("First Number Is Positive.\n");
    }
    else if(x<0)
    {
        printf("First Number is Negative.\n");e
    }
}
//Function Prototype of First Number..
int number2(int y)
{
    if(y>0)
    {
        printf("Second Number Is Positive.\n");
    }
    else if(y<0)
    {
        printf("Second Number is Negative.");
    }
