Operator :Operators in C program is special symbol or word which directs the
compiler to perform arithmetical or logical works, i.e. the characters which is used in C
for special purpose so this character is called operators.
Different types of operators :
 Arithmetic operator
 Unary operator
 Relational operator
 Logical operator
 Assignment operator
 Conditional operator
Arithmetic Operators List :
Arithmetic Operators niterians.blogspot.com
Operator Meaning
+ Addition or unary plus
- Subtraction or unary minus
* Multiplication
/ Division
% Modulo division
++ Increment operator increases the integer value
by one.
-- Decrement operator decreases the integer
value by one.

Arithmetic expressions:
An arithmetic expression is a combination of variables, constants, and
operators.
For example,
Arithmetic expressions: niterians.blogspot.com
a*b-c a*b-c
(m+n)(x+y) (m+n)*(x+y)
ax2
+bx+c a*x*x+b*x+c

printf("Enter the value of a : ");
scanf("%d", &a);
printf("Enter the value of b : ");
scanf("%d", &b);
c =a+b;
printf("Sum of a and b is %d ", c);
}
