Signed unsigned data types

#1

what happens when any variable is initialized using signed and unsigned data type?

#2

@tusharbhardwaj127
int a; now a can store negative and positive values as well.
unsigned int a; a cannot store negative values.
but the range of positive values in unsigned would be twice as that of int.

#3

what in case of signed = “value” ? if data type not provided then it will be an error?

#4

can you please share me any link through which i can read about this signed and unsigned data types?

#5

No, it wont show error, but it will not give correct result.
