To get the second element: So the [] indexing operator is a special form of the * operator, and it works like this: Arrays are special and can be converted to pointers transparently. This highlights another way to get from a pointer to a value, I'll add it to the explanation above.

Operators in C - Programiz
C programming has two operators increment ++ and decrement -- to change the value of an operand (constant or variable) by 1. Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand. int a = 10, b = 100;

C Operators - Online Tutorials Library
We shall learn more about arithmetic operators in C in a subsequent chapter. The following table shows all the arithmetic operators supported by the C language. Assume variable A holds 10 and variable B holds 20 then −. Show Examples. Adds two operands. Subtracts second operand from the first. Multiplies both operands.

Modulo Operator (%) in C/C++ with Examples - GeeksforGeeks
In C or C++, the modulo operator (also known as the modulus operator), denoted by %, is an arithmetic operator. The modulo division operator produces the remainder of an integer division which is also called the modulus of the operation. If x and y are integers, then the expression: pronounced as "x mod y".

Operators in C - GeeksforGeeks
In this article, we will learn about all the operators in C with examples. What is an Operator in C? A C operator can be defined as the symbol that helps us to perform some specific mathematical, relational, bitwise, conditional, or logical computations on values and variables. The values and variables used with operators are called operands.

Conditional or Ternary Operator (?:) in C - GeeksforGeeks
Working of Conditional/Ternary Operator in C. The working of the conditional operator in C is as follows: Step 1: Expression1 is the condition to be evaluated. Step 2A: If the condition (Expression1) is True then Expression2 will be executed. Step 2B: If the condition (Expression1) is false then Expression3 will be executed.
