C progamming?

I need to do this assignment with these in the progam:


Read a number


Print the number back to the user


If the number is negative, program should quit. Assume positive integer values for all other questions


The number before


The number after


Is Even or Odd





what I have so far is





#include %26lt;stdio.h%26gt;





int main()





{


int num;





printf("Enter your number: ");


scanf("%d", %26amp;num);


printf("Your number is %d\n", num);





return 0


}


I seem to have the first 2 done but i run into trouble with the rest of them... can someone help me with this

if (num %26lt; 1) {


return 0;


}


printf ("Number before is %d and the number after is %d\n", num-1, num+1);


if(num % 2) {


printf ("Your number is odd\n");


} else {


printf ("Your number is even\n");


}
