C Programming beginners, if...else programe

//SIMPLE IF..ELSE PROG. to FIND NUMBER IS ODD or EVEN NUMBER
#include<conio.h>
#include<stdio.h>

scanf("%d",&n);
if(n%2==0)

}
else
{
printf("%d is ODD number",n);
}
getch();
}
O/P:
Enter Number: 10
10 is EVEN Number

Enter Number: 13
13 is ODD number

//SIMPLE IF..ELSE PROG. to FIND NUMBER IS ZERO/POSITIVE/NEGATIVE
#include<conio.h>

}
else if(n>0)
{
printf("%d is POSITIVE number",n);
}
else
{
printf("%d is NEGATIVE number",n);
}
getch();
}

O/P:
Enter Number: 0
You have entered ZERO

Enter Number: 12
12 is POSITIVE number

Enter Number: -25
-25 is NEGATIVE number

//SIMPLE IF..ELSE PROG. to FIND NUMBER RANGE

#include<conio.h>
#include<stdio.h>
void main()
{
int n;
clrscr();
printf("Enter POSITIVE NUmber:");
scanf("%d",&n);
if(n>=0)

}
else
{

}
}
else
{

}

}

O/P:
Enter Number: 25
25 is in between 21 to 50

Enter Number: 7
7 is in between 0 to 10

Enter Number: -9
-9 is NEGATIVE NUMBER

Enter Number: 15
15 is in between 11 to 20

Enter Number: 85
85 is in between 51 to 100

Enter Number: 105
105 is greater than 100
