## 9. What's an unsigned integer? coderanch.comHi Mr. Junta, you overthrown any goverments lately? Well, hopefully you wil find my answer better than my humour: An unsigned int, or an unsigned whatever (byte,char), means that the value has no sign to show whether the value is positive or negative.

## 15. why does core java doesnt have unsigned int?? coderanch.comYou are obviously taking the bits of the signed number -5, which in 32 bits is 2^32 - 5. Since C isn't a type-safe language, it will take the same bit pattern as that and covert it to positive or negative numbers depending on whether you use the %u or %i flags to display it.#include |
