ARITHMETIC OPERATORS

These operators are responsible for performing arithmetic or mathematical operations like addition (+), subtraction (-), multiplication (*), division (/), the remainder of the division (%), increment (++), and decrement (–). 

Symbol	Operator	Description	Syntax
+	Plus	Adds two numeric values.	a + b
–	Minus	Subtracts right operand from left operand.	a – b
*	Multiply	Multiply two numeric values.	a * b
/	Divide	Divide two numeric values.	a / b
%	Modulus	Returns the remainder after diving the left operand with the right operand.	a % b
+	Unary Plus	Used to specify the positive values.	+a
–	Unary Minus	Flips the sign of the value.	-a
++	Increment	Increases the value of the operand by 1.	a++
--	Decrement	Decreases the value of the operand by 1.	a--

 

SIMPLE C PROGRAMMING USING ARITHMETIC OPERATORS

// C program to illustrate the arithmatic operators

#include <stdio.h>

int main()

{

            int a = 25, b = 5;

            // using operators and printing results

            printf("a + b = %d\n", a + b); // addition

            printf("a - b = %d\n", a - b); // subtraction

            printf("a * b = %d\n", a * b); // multiplication 

            printf("a / b = %d\n", a / b); // division

            printf("a % b = %d\n", a % b); //modulus

            printf("+a = %d\n", +a); //unary plus

            printf("-a = %d\n", -a); // unary minus

            printf("a++ = %d\n", a++); // increment 

            printf("a-- = %d\n", a--); // decrement 

            return 0;

}

        Output

                a + b = 30

                a - b = 20

                a * b = 125

                a / b = 5

                a % b = 0

                +a = 25

                -a = -25

                a++ = 25

                a-- = 26

 # Why in the above program, in the last expression (a--) how the output will be 26?
