Share Improve this answer Follow Web91 I was curious to know what would happen if I assign a negative value to an unsigned variable. The code will look somewhat like this. unsigned int nVal = 0; nVal = -5; It didn't give me any compiler error. When I ran the program the nVal was assigned a strange value! Could it be that some 2's complement value gets assigned to nVal? c++

WebMay 21, 2024 · How can an unsigned int store a negative number? It doesn't. Instead, it stores a representable number that is congruent with that negative number modulo the number of all representable values. The same is also true with results that are larger than the largest representable value. Is it save to be used or does this yield undefined … WebDec 9, 2024 · Some properties of the int data type are: Being a signed data type, it can store positive values as well as negative values. Takes a size of 32 bits where 1 bit is used to store the sign of the integer. A maximum integer value that can be stored in an int data type is typically 2, 147, 483, 647, around 231 – 1, but is compiler dependent.
WebJun 27, 2015 · This explanation is also the reason why negative indexes in arrays work in C; i.e., if I access a [-5] it will give me: Base Address of your Array a + (index of array *size of (data type for array a)) Base Address of your Array a + (-5 * size of (data type for array a)) i.e. 1000 + (-5*2) = 990 It will return the object at location 990.
