I'm going with C. The program will output '11' because it's going to treat the input 'true true' as two integer values and print them out.

B, easy. The program will output 'falsefalse' because the input 'true true' will be interpreted as two boolean values that are both false.

I agree with Laurena. Since the input is true true, the program will output truetrue as the values of a and b.

E, definitely E. This code has some serious issues and won't compile at all. Who wrote this, a monkey?

D looks good to me. The program will output '00' because the boolean values 'true' and 'true' will be interpreted as 1 and 1, which get printed as '00'.

I think the answer is A. The program will output 'truetrue' since the input 'true true' will be read as two boolean values and then printed out.

I think the program will output truetrue because it will print the values of a and b without any modifications.
