conditional operators in c special operators in c

1. Operators in C
Conditional Operator
Special Operator

2. Conditional Operator
As conditional operator works on three operands, so it is also known as
the ternary operator.
The behavior of the conditional operator is like the if-else statement as
'if-else' statement is also a decision-making statement.
The conditional statements are the decision-making statements which
depends upon the output of the expression. It is represented by two
symbols, i.e., '?' and ':’.
Syntax:
variable = Expression1 ? Expression2 : Expression3

3. Examples
Consider two variables A=10 and B=20
Max = (A>B) ? A : B
Consider three variables X=10, Y=40 and Z=35
Max= (X>Y) ? ((X>Z) ? X : Z ) : ( (Y>Z) ? Y: Z )
True
False

5. Special Operators
Some other special operators which are supported by C are-
Operator Description Example
sizeof() The sizeof operator will return
the size of the variable as result.
If a is an integer variable, then
sizeof(a); will return result of 4 or
2 according to compiler.
& The address operator will return
the address of the variable as
result.
If a is a variable, then &a will
return the actual memory location
of the variable a.
* This operator is used as the
pointer to the variable
If int a=5, *p; and P=&a; then
*p will return 5

6. Precedence and Associativity
The precedence of operators determines which operator is executed
first if there is more than one operator in an expression.
For example :
int a = 14-2*3;
8
The associativity of operators determines the direction in which an
expression is evaluated.
For example:
a = b;
Value of b is assigned to a. because the associativity of the = operator
is from right to left.

7. Category Operator Associativity
Postfix () [] -> . ++ - - Left to right
Unary + - ! ~ ++ - - (type)* & sizeof Right to left
Multiplicative * / % Left to right
Additive + - Left to right
Shift << >> Left to right
Relational < <= > >= Left to right
Equality == != Left to right
Bitwise AND & Left to right
Bitwise XOR ^ Left to right
Bitwise OR | Left to right
Logical AND && Left to right
Logical OR || Left to right
Conditional ?: Right to left
Assignment = += -= *= /= %=>>= <<= &= ^= |= Right to left
Comma , Left to right
The operators with the highest precedence are listed at the top of the table.
