PAT B1011 [A + B] and C

PAT B1011 [A + B] and C

Given interval [-2 ^ 31, 2 ^ 31] three integers A, B and C in, please determines whether A + B is greater than C.
Input format:
Enter line 1 gives a positive integer T (<= 10), a number of test cases. T is then given set of test cases, each per line, the order is given A, B and C. Between integer separated by a space.
Output format:
for each test case, the output in line "Case #X: true" if A + B> C, and otherwise outputs "Case #X: false", where X is the test case number (starting from 1).
