he following code is not well-written. What does the program do? Void main() { int a=1, b=2, c=3,d=4; printf("%d %d", a, b); printf (" %d %d", c, d); }

The program declares four integer variables (a=1, b=2, c=3, d=4) and prints them using two printf statements. The first printf outputs a and b, the second outputs c and d with a leading space. The output is 1 2 3 4. Option A and B are incorrect because the code compiles and runs without errors. Option D is incorrect because option C is valid.
