A bit is the smallest unit of digital information. It can have a value of either 0 or 1.
A bit is a binary digit, represented as either 0 or 1.
It is the basic unit of information used in computing and digital communications.
A group of 8 bits is called a byte.
The size of a bit is dependent on the architecture of the computer system.
C is a programming language and does not have a fixed number of bits.
C is a high-level programming language that can be compiled to run on different architectures with varying bit sizes.
The number of bits in C depends on the hardware architecture it is compiled for.
For example, C code compiled for a 32-bit architecture will have 32-bit integers, while code compiled for a 64-bit architecture will have 64-bit integers.
