What is the problem with unsigned integers?
The problem here is that an unsigned integer is never negative. will always be true. Thus you get an infinite loop. When it drops below zero, it wraps around to the largest value unsigned value. Thus, you will also be accessing x [i] out-of-bounds. This is not a problem for signed integers because it will simply go negative and thus fail i >= 0.
Does C++ support unsigned integers?
C++ also supports unsigned integers. Unsigned integers are integers that can only hold non-negative whole numbers. To define an unsigned integer, we use the unsigned keyword. By convention, this is placed before the type: A 1-byte unsigned integer has a range of 0 to 255. Compare this to the 1-byte signed integer range of -128 to 127.
