In this tutorial, we are going to learn about C arithmetic operations on integers, characters, mixed data types operators.

## 1. Arithmetic Operators – integers:

An **operator** is a special symbol used to manipulate data. The data items that the operators act upon are called *operands*.

The operator that works on a single operand is called a **unary** operator and that which works on two operands is known as a binary operator.

**C** provides many types of operators. They are:

- Arithmetic
- Unary
- Relational and equality
- Logical
- Assignment
- Conditional
- Bitwise and Special operators

In this article let’s see the **Arithmetic operators in C**, we have 5 arithmetic operators in C:

Arithmetic operators are applied on numeric operands. Thus the operands can be integers, floats or characters (Since a character is internally represented by its numeric code).

The *remainder operator* (%) requires that both the operands be *integers* and the second operand be *non-zero*. Similarly, the *division operator* (/) requires that the second operand be *non-zero*.

The format for the usage of the arithmetic operator is as follows:

`operand1 operator operand2`

According to the coding conventions in C, a single space should be provided to the left and to the right of an operator.

The table given below demonstrates the use of various *arithmetic operators* using two variables *p* and *q* of type int with values 35 and 17 respectively:

## 2. Arithmetic Operators – float:

**Division** of one integer by another integer is referred to as integer division. This operation always results in an integer with a truncated quotient.

If a *division* operation is carried out with two *floating-point numbers* or with one *floating-point number* and one *integer*, the result will be a *floating-point quotient*.

The table given below demonstrates the usage of various *arithmetic operators* using two variables num1 and num2 of type float with values 12.5 and 2.0 respectively:

Note that the **remainder operator** (%) is not applicable for **floating-point numbers**.

## 3. Arithmetic Operators – characters:

The table given below demonstrates the use of various **arithmetic operators** using two variables v1 and v2 of type char with values ‘Á’ and ‘D’ respectively.

In the above example, the character ‘A’ is substituted with its ASCII value **65,** and ‘D’ is substituted with **68. **The character ‘5’ is substituted with its ASCII value **’53’. **The integer value 5 is used as it is.

The following table demonstrates the usage of various **arithmetic operators** using two variables **a and b** of type **int** with values 11 and -3 respectively.

## 4. Arithmetic Operators – mixed data types:

Arithmetic operators can be used in expressions with operands of different data types.

For example, the **addition operator** (+) can be used on **int** and **float** data types with the result being a **float** data type.

If the same is performed on **float** and **double** data types, the result will be a **double** data type, i.e., the result will always be of the **data type** with the highest memory capacity.

Consider the following examples with different combinations of arithmetic operators and data types.
