Arithmetic

+, -, *, / (quotient operator), % (remainder operator or modulus)

Divison and Modulus operator

in $n/d$ if $n<d$ then output is $0$

in $n\%d$ if $n<d$ then output is $n$

Rules for arithmetic operators:-

1. Integer Divison

   • int $/$ int is always int

2. Modulus with Integers Only

   • Modulus operator cannot be used with floating point numbers as by default every float is treated as double. C is an expanding language.

   // Example of incorrect usage:
   float result = 5.2 % 2; // Error
   

3. Operator Precedence

   • If more than 1 operator is present in an expression then precedence rule will be applied.

4 Associativity

• If multiple operations with the same precedence appear, the associativity rule determines the order of evaluation.
• Arithmetic Operators are left associative.
