Write a program in C that takes in two integers as inputs and outputs the largest value. If the two integers are the same, output the integers' value. 
 
a) if (num1 > num2) printf(%d, num1); else printf(%d, num2); 
b) if (num1 >= num2) printf(%d, num1); else printf(%d, num2); 
c) if (num1 < num2) printf(%d, num1); else printf(%d, num2); 
d) if (num1 <= num2) printf(%d, num1); else printf(%d, num2);
