How long will it take for an unsigned 64 bit counter to overflow on a xxx ghz machine and another coding problem that requires recursive programming.

2 Answers

unsigned 64-bit counter = 2^64. xxx GHz machine = xxx * 10^9 cycles/second, ie. 1 cycle is 1/(xxx * 10^9) seconds. Assuming the counter increments 1 every cycle, then it'll max out at: 2^64 / (xxx * 10^9) seconds.
