What are C arithmetic instructions?

Answer 1

C does not have instructions of any kind, it has operators and functions. The arithmetic operators are provided for all built-in numeric types (integer and real numbers, including mixed mode arithmetic). They are as follows:

Unary operators:

positive (+) e.g., +x

negative (-) e.g., -x

prefix increment (++) e.g., ++x prefix decrement (--) e.g., --x

postfix increment (++) e.g., x++

postfix decrement (--) e.g., x--

Binary operators:

add (+) e.g., x + y

subtract (-) e.g., x - y

multiply (*) e.g., x * y

divide (/) e.g., x / y

modulo (%) e.g., x % y
