Arithmetic Operators In Computer Programming.

 

                       Arithmetic Operators

Objectives:

To familiarize students with arithmetic, logical and relational operators 

Tools:

Turbo C IDE  

Procedure:

Writing a program that performs the following

•       Receive two numbers as input from the user

•       Find summation of two numbers using arithmetic operator

•       Display on the screen to the user

Arithmetic operators are commonly used in a variety of programming languages. In C, there are five of them and they all take two OPERANDS – an expression that is required for an operator to work. For example, for 2 + 3, 2 and 3 are considered as operands. The following table shows Arithmetic Operators:

Operator Name	Symbol
Multiplication	*
Division	/
Addition	+
Subtraction	-
Modulus	%

In addition to the division operator, C also provides modulus operator (%) which returns the remainder on dividing one integer with another. Thus the expression 10/2 yields 5, whereas 10%2 yields 0. Modulus operator cannot be applied on the float. Also using %, the sign of the remainder is always the same as the sign of numerator. Thus -5 % 2 yields -1, whereas 5 % -2 yields 1.

Step 1:

Create a New file and save it as operators.c

Step 2:

Write the following code as shown in the figure below

Step 3:

Save the file again, compile and execute it to see the output as shown in the figure below
