+1

means it can store positive integer value as well as negative integer value

+1

yeah that's right

+1

no no wait signed means all the no s but unsigned means only positive numbers it is used when we have some values in positive terms only so in order to save memory we use unsigned , range of variable can be doubled by unsigned and writing signed or not will not make such difference

oh OK thanks a lot for that! Do u mean that unsigned=0, and signed=either of a +ve or -ve value? So by saying, an integer value that can be signed or unsigned, they're really saying it can be literally ANY integer, whether it's +ve, -ve or even just 0. Is the right interpretation? THANKS :D
