Operators in C: What Are Operators in C & How Many Types Exist

It is imperative to know the operators in c as almost every computation, bit manipulation, and pointer dereference depends on the operator precedence and associativity. When asking what are operators in c, they are the built-in symbols that are used to tell the compiler to manipulate operands in mathematical, relational, logical, or memory operations. If students ask how many types of operators in c exist, the language can be grouped as arithmetic, relational, logical, bitwise, assignment, increment/decrement, conditional (ternary), and special (sizeof and pointer dereferencing * and &), which can lead to undefined behavior if they misuse precedence or signed shift rules.

Arith: 17 / 5 = 3, 17 % 5 = 2
Bitwise OR: 0x07, AND: 0x00
