For a

**signed integer**one bit is used to indicate the sign - 1 for negative, zero for positive. Thus a 16 bit**signed integer**only has 15 bits for data whereas a 16 bit**unsigned integer**has all 16 bits available. This means**unsigned integers**can have a value twice as high as**signed integers**(but only positive values).Correspondingly, what is signed and unsigned integer in C?

Because it's all just about memory, in the end all the numerical values are stored in binary. A 32 bit

**unsigned**integer can contain values from all binary 0s to all binary 1s. When it comes to 32 bit**signed**integer, it means one of its bits (most significant) is a flag, which marks the value to be positive or negative.What is signed and unsigned numbers?

For

**signed**binary**numbers**the most significant bit (MSB) is used as the sign bit. If the sign bit is “1”, then the**number**is negative in**value**. The remaining bits in the**number**are used to represent the magnitude of the binary**number**in the usual**unsigned**binary**number**format way.What is the difference between signed and unsigned data types?

**Signed data types**can hold both positive and negative values.

**Unsigned data types**can hold large positive values but cannot hold negative values.

**Different**ways are used represent

**signed**values, the most common one is Two's complement method.
