This is a c++ code. Write a series of assignment statements (complete executable code) that find the first three positions of the string and in a string variable sentence. The positions should be stored in int variables called first, second and third. You may declare additional variables if necessary. The contents of sentence should remain unchanged. The sentence can be completely random.

Im having a large problem with this. It's a simple c++ code, but im unable to get it. Thank you.
