The document discusses different types of operators in C programming including arithmetic, relational, logical, bitwise, assignment, compound assignment, shift, increment, and decrement operators. Examples are provided to demonstrate the use of arithmetic, relational, and logical operators. The increment and decrement operators ++ and -- are also explained, distinguishing between pre-increment/decrement and post-increment/decrement.

1. OPERATORS
Arithmetic (+,-,*,/,%)
Relational (<,>,<=,>=,==,!=)
Logical (&&,||,!)
Bitwise (&,|)
Assignment (=)
Compound assignment(+=,*=,-=,/=,%=,&=,|=)
Shift (right shift >>, left shift <<)

2. Example for Arithmetic operator
Add_Two_Numbers (a,b) /* Add a and b */
int a,b;
{
int c;
c = a + b;
printf ("%d",c);
}

3. Example for Relational operator
myfunction (a,b) /* breaking out of functions early */
int a,b;
{
while (a < b)
{
if (a > b)
{
return (b);
}
a = a + 1;
}
}

4. Example for logical operator
if ((i > 2) && (i < 4))
{
printf ("i is three");
}

5. OPERATORS(Contd.)
Increment and Decrement Operators
++ Increment operator
-- Decrement Operator
k++ or k-- (Post-increment/decrement)
k = 5;
x = k++; // sets x to 5, then increments k to 6
++k or --k (Pre-increment/decrement)
k = 5;
x = ++k; // increments k to 6 and then sets to the
resulting value, i.e., to 6

6. OPERATORS(Contd.)
Increment and Decrement Operators
++ Increment operator
-- Decrement Operator
k++ or k-- (Post-increment/decrement)
k = 5;
x = k++; // sets x to 5, then increments k to 6
++k or --k (Pre-increment/decrement)
k = 5;
x = ++k; // increments k to 6 and then sets to the
resulting value, i.e., to 6
