I work with a lot of calculation code written in c++ with high-performance and low memory overhead in mind. It uses STL containers (mostly std::vector) a lot, and iterates over that containers almost in every single function. The iterating code looks like this: But it produces the signed/unsigned mismatch warning (C4018 in Visual Studio). Replacing … Read more
The “signed” indicator means that the item can hold positive or negative values. “Unsigned” doesn’t distinguish between positive and negative values. A signed/unsigned variable can refer to any numerical data type (such as binary, integer, float, etc). Each data type might be further defined as signed or unsigned. For example, an 8-bit signed binary could … Read more
How do I see the type of a variable whether it is unsigned 32 bit, signed 16 bit, etc.? How do I view it?
Am I correct to say the difference between a signed and unsigned integer is: Unsigned can hold a larger positive value and no negative value. Unsigned uses the leading bit as a part of the value, while the signed version uses the left-most-bit to identify if the number is positive or negative. Signed integers can … Read more
